The differential diagnosis includes primary bone tumors, sarcoma (especially in area of previous radiation), Paget's disease, and chronic osteomyelitis (especially tuberculous). A rational and systematic approach can often result in a specific diagnosis or a short differential diagnosis. A systematic approach of lytic bone lesions along with the differential diagnosis of head masses are skills the clinician should develop to promptly recognize this condition considering further complications of delayed treatment. ** Lytic bony lesions or end-organ damage (hypercalcemia/ anemia/ renal insufficiency etc) No lytic lesions or end-organ damage ** Critical points: bone marrow plasma cells or M-protein above threshholds separates asymptomatic myeloma from MGUS and bone or other end organ damage separates symptomatic from asymptomatic myeloma. MR imaging is the best modality for local staging. The distribution of 18 F-FDG–avid bone lesions on PET/CT was consistent with other studies using CT or radiographic skeletal survey ( 3 , 16 ). In fact, the findings derived from xâ ? ?rays allow formulation of a reasonable hypothesis regarding the histological nature and possible differential diagnosis of a lesion. The histopathological differential diagnosis was cystic angiomatosis and Gorham's disease, as. We report a case of a 49-year old Ukrainian male who presented with bone pain secondary to a lytic bone lesion who was diagnosed with HCL. The most common location is the vertex, accounting for over 70 % of cases. Introduction. The differential diagnosis is broad, and radiologic evaluation is often requested. Freemasonry in Abingdon, News from Abbey Lodge of Abingdon Freemasons in the masonic province of Berkshire. The differential diagnosis of lytic bone lesions in a person ≥40 years old includes 1) multiple myeloma, which has a classic triad: marrow plasmacytosis, lytic bone lesions, and a serum and/or urine M component; and 2) metastatic cancer. This distinction appears useful in the differential diagnosis of osteoblastic reactions, since certain diseases may exclusively present as scattered (solitary or multiple) sclerosis. 1 The novel criteria for the diagnosis of symptomatic multiple myeloma have revealed the value of modern imaging for the management of patients with multiple myeloma, as they include (1) the presence at. Bone marrow can be the nidus of malignancy in multiple myeloma, lymphoma, and leukemia. The biopsy can be incisional or excisional. To better understand these disorders, we discuss several common rib pathologies in the context of their. compared multidetector row CT with conventional radiography and MR imaging in patients with newly diagnosed multiple myeloma [ 16 ]. Rare; usually affects long tubular and flat bones but may occur in any bone Also occurs in skin and subcutis Mean age 34 - 46 years, range teens to 70s 25% multifocal Radiology description. A and B, A lytic lesion with adjacent sclerotic changes is shown with ill-defined margins. Bubbly Lesions of Bone Eisenberg Residents’ Section Pattern of the Month Bubbly lesions of bone are common findings on skeletal radiographs. Most common presentation: multiple lytic 'punched out' lesions. haemophilum should be entertained so that special culture media can be used and appropriate. rts sarcoidosis but was completely asymptomatic. [] They account for less than 5% of new bone tumors diagnosed every year in the United States. Commonly in back, ribs, extremities, often worse with movement. Prosthetic loosening/infection** incl acetabulum. The predilection for the knee joint is perhaps associated with this region having the most marked bone length growth. The cells may cause soft-tissue masses or lytic lesions in the skeleton, may involve any bone, but the predominant sites include the vertebral column, ribs, skull, pelvis and femora. Metastases: Nonspecific lytic lesion which may have aggressive or non-aggressive features. Osteomyelitis. Bone window axial section CT Brain demonstrating multiple punched out lytic lesions involving skull bones (red arrows). 2018-02-01. Freemasonry in Abingdon, News from Abbey Lodge of Abingdon Freemasons in the masonic province of Berkshire. A patient with multiple radiolucencies of the jaws or other bones may also have multiple myeloma [9] 13. In time, myeloma cells collect in the bone marrow and in the solid parts of bones. unexplained anaemia •Hypercalcemia •Renal failure SPB myeloma. Axail CT image prior to biopsy demonstrates the lytic appearance of the lesion within the thick-ened cortical bone. It consists of a bony outgrowth with a cartilage cap. If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. This article reviews semiological aspects of bone tumors: patient. The diagnosis of a large solitary lytic skull vault lesion in adults is a challenge due to variable aggressiveness and overlapping features. Particularly for lytic lesions, there is a concern whether an underlying primary tumor or a metastatic deposit is present. These produce bubbly lesions. The biopsy can be incisional or excisional. , serum ALP). Chemico-biological interactions 20180925. Mahnken et al. We performed X-ray of the skull that revealed multiple punched out lesions and X-ray of the pelvic bones also revealed multiple lytic lesions. Appearances are sometimes nonspecific leading to consideration of a broad differential diagnosis. 6 Anemia occurs in approximately 75% of patients and contributes to fatigue. periapical (radicular) cyst (60% of odontogenic cystic lesions 4) periapical abscess. The presence of multiple osteolytic lesions, biclonal gammopathy on serum protein electrophoresis and immunofixation, negative Epstein-Barr virus-encoded small RNAs on IHC led to revision of the diagnosis to plasmablastic variant of multiple myeloma. They are by no means exhaustive lists, but are a good start for remembering a differential for a lucent/lytic bone lesion and will suffice for >95%. neoplastic plasma cells produces immunoglobulins. bone-forming tumors. The following case describes a patient with known polycythemia vera (PV) that presented with signs of multiple myeloma, including hypercalcemia, anemia, and lytic lesions of the thoracic spine and skull. However, up to 30 percent of patients are diagnosed incidentally while being evaluated for unrelated problems. Here images of a 30-year-old male. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs, i. Multiple myeloma is a bone marrow disease characterized by the presence of malignant plasma cells, & abnormal serum &/or urine immunoglobulin secondary to clonal plasma cell expansion. # Lipomas, epidermoid cysts, dermoid. 12688/f1000research. Usually no increased uptake on bone scan. In this article, which is the first in a series of three, we will discuss the most common bone tumors and tumor-like lesions in alphabethic order. Smoldering myeloma. IB Well-defined geographic lytic lesion with a sharp margin without a sclerotic rim Most lesions are benign, although differential diagnosis may include metastatic disease and myeloma IIa Geographic lytic lesion with partial or circumferential ill-defined margins Some benign causes, but differential diagnosis should include malignancy. Radiographically, these lesions initially present as lytic lesions of the bone (classical 'salt and pepper' appearance and 'ground glass' appearance have also been described), which, upon treatment of the underlying. finding of lytic bone lesion on imaging prompted further investigations. To better understand these disorders, we discuss several common rib pathologies in the context of their. Focal sclerotic bone lesions are encountered commonly in clini cal practice. All the films were reviewed by. Systematic assessment of the above lesions, correlation with plain films, and description in a structured reporting format are very useful to arrive at a definitive diagnosis (or the most relevant differential diagnosis), and to decide upon further management, including biopsy, surgery, and follow-up strategies. In view of the multiple sites of bone pain and deformity, skeletal survey was ordered which revealed multifocal lytic expansile lesions with gross bony destruction and soft tissue swelling. Being a planar structure, fetal diagnosis of aorto-pulmonary window poses great challenge. Multiple myeloma can cause problems throughout the body. By immunohistochemistry, the tumor was positive for pan-cytokeratin (CK), arginase 1, HepPar1, and CD138 (panels C and D) and negative for κ and λ, supporting. [] Radiologists need to be aware that additional eosinophilic granuloma of bone, occurring as long as 4 years after initial diagnosis, should be. Multiple myeloma usually is characterized by the development of lytic bone lesions. INTRODUCTION. Laboratory workup was not indicative of myeloma. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in MR image of a mixed lytic and Metastasis: Mixed Lytic and Blastic Bone Lesion - Mets. Bone involvement is rare, and spinal involvement is even more rare. bution is noted in the literature. Differential Diagnosis of Periapical Radiopacities and Radiolucencies. However, we can further define the location of the lesion by noting its relationship to the physis. Bone and cartilage tumors may be differentiated according to clinical features, laboratory findings, imaging features, histological features, and genetic studies, from other diseases that cause limited range of motion, limb deformity, bone pain, and local swelling. However, malignant metastatic spread to the spine involves the vertebral cortex rather than the bone marrow itself, a distinction that is often missed and therefore misleading. Sclerotic Cortical lesions. Lucent Bone Lesions: Differential Diagnosis #12. Osteosarcoma – more commonly involves long bones, but can affect chest wall, often with lung mets. The differential diagnosis of multiple myeloma is shown in Table 2. Bone marrow can be the nidus of malignancy in multiple myeloma, lymphoma, and leukemia. Coronal CT reformat of lumbar. 10 On MRI, decreased T1 signal and increased signal on susceptibility imaging, T2, and STIR sequences represent bone marrow edema. Other lesions in the differential diagnosis are reactive parosteal or periosteal lesions (e. Bone involvement is rare, and spinal involvement is even more rare. Most expansile, lucent lesions are located in the medullary space of the bone. Multiple myeloma must be included in the differential diagnosis of any lytic bone lesion, whether well-defined or ill-defined in age > 40. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Common permeative lesions can be recalled by the word POLLEN: As the table above shows, all these entities need medical and/or surgical management. Spread hematogenously. It most commonly occurs in males in their 60's. Histology reveals cartilage with a layer of smooth, thin bone surrounding. The initial differential diagnosis suggested metastatic disease to bone in addition to multiple myeloma and lymphoma, in that order. Most bone tumors present as well-defined osteolytic lesions, sometimes referred to as 'bubbly lesions'. The differential diagnosis of diaphyseal lesions includes fibrous dysplasia, osteoblastoma, histiocytosis, osteomyelitis, and others. Fluorodeoxyglucose-avid and corticalis-disrupting lytic lesions also occur in benign bone disease. CT scan, MRI, and bone scan from a 27-year-old woman with grade 1 angiosarcoma who presented with a pathological fracture through a lytic lesion on her left clavicle. Epstein-Barr virus, which mainly infects B cells and epithelial cells, has two modes of infection: latent and lytic. Plasmacytoma/Myeloma Vikram Deshpande, MD G. compared multidetector row CT with conventional radiography and MR imaging in patients with newly diagnosed multiple myeloma [ 16 ]. Multiple lesions in Young Patient: EG Fibrous dysplasia Leukemia Lymphoma Hemangioendothelioma Enchondroma / Olliers / Marfucci's Osteochondroma / MHE NOF / Jaffe-Campanacci syndrome. In younger patients with vertebral body lesions most likely diagnosis is histiocytosis, whereas the lesions involving posterior elements of the spine may have ABC, Osteoblastoma, and Tuberculosis as differentials. usually found in patients <20 years of age; location usually found in the proximal humerus of young patients ; can be found in other locations including proximal femur, distal tibia. Osteomyelitis, tuberculosis, sarcoidosis. Multiple myeloma must be included in the differential diagnosis of any lytic bone lesion, whether well-defined or ill-defined in age > 40; The most common location is in the axial skeleton (spine, skull, pelvis and ribs) and in the diaphysis of long bones (femur and humerus) Most common presentation: multiple lytic 'punched out' lesions. bone tumors. There is also bone destruction and pathologic fractures of both third toes and the distal right 5th toe (black arrows). Paget's disease and multiple myeloma are very rare at this age. Bone marrow is an organ that is evaluated routinely during MRI of the spine, particularly lumbar spine evaluation. Osseous metastatic lesions have multiple appearances and therefore are often included in the differential for atypically appearing sclerotic or lytic lesions. Chronic nonbacterial osteomyelitis (CNO) is a focal sterile inflammatory osteitis in children that most commonly develops in the long bones, but can occur in any bone. Epstein-Barr virus, which mainly infects B cells and epithelial cells, has two modes of infection: latent and lytic. Skeletal involvement includes polyostotic lytic bone lesions or diffuse osteoporosis attributable to bone resorption induced by elevated parathyroid hormone and manifested clinically by The differential diagnosis of multiple lesions in children includes multiple. usually associated with extensive bone marrow fibrosis, and its presentation with radiographic lytic lesions or periosteal reaction in long bones has been described in four case reports involving children (1–4). 1, 2020, which is a divisional of U. Serum Calcium >11 mg/dl (or >1 mg/dl above upper range of normal) Renal Insufficiency. This was a known, biopsy-proven diagnosis prior to the bone scan. Although false negatives can be seen (such as in the case of multiple myeloma or in very aggressive lytic tumors), the bone scan is a reliable method for evaluation of most bony processes around the hip and pelvis. See full list on appliedradiology. The most common scintigraphic pattern for ABC is a cold center with a rim of mild increased activity (the “donut sign,” which may also be seen in giant cell tumors and other. Lymphoma should be considered in the differential diagnosis of any sclerotic vertebral lesion. Soap-Bubbly Lesion. Background Lesions involving pelvic bone are sometimes difficult to evaluate due to singular anatomy of the pelvic bones. However, using the criteria listed in the section on presenting complaints and the section on radiographic analysis. This article reviews lesions that classically arise from the posterior elements, mainly aneurysmal bone cyst, osteoid osteoma/osteoblastoma, myeloma, and osteochondroma ; hemangioma, and giant cell tumor, which typically. Axail CT image prior to biopsy demonstrates the lytic appearance of the lesion within the thick-ened cortical bone. Request PDF | Pathological Fracture of the Tibia as a First Sign of Hyperparathyroidism – A Case Report and Systematic Review of the Current Literature | Background/aim: Pathological fractures. This patient also had recurrent parotid gland enlargement. SCLEROTIC BONE LESION By Dr. 1, 2020, which is a divisional of U. These can have a diverse imaging appearance, particularly after chemotherapy. Can cause bony destruction with lytic and blastic lesions and associated pleural effusions. In the article Bone Tumors - Differential diagno-sis we discussed a systematic approach to the differential diagnosis of bone tumors and tu-mor-like lesions. solitary lesion: chondrotumor, GCT and lymphoma. On the other hand, in the radiologic evaluation of a purely lytic lesion at the articular end of a long bone that looks like a giant cell tumor, plasmacytoma might enter into the differential diagnosis, whereas for a pathologist examining the same lesion (which in fact is a giant cell tumor), the differential diagnosis will obviously include. Box 139-1 lists common pediatric bone tumors in accordance with the peak age at which they most commonly occur. These cells are part of your immune system, which helps protect the body from germs and other harmful substances. Geographic lesion: If the tumor is not aggressive, bone gets time to lay itself down producing a distinct margin around the lesion. A solitary presentation is referred to as plasmacytoma. Can cause bony destruction with lytic and blastic lesions and associated pleural effusions. (particularly if the lesion is at the skull base) - bone marrow evaluation, a skeletal survey, a bone scan, and serum and urine protein electrophoresis. Most common presentation: multiple lytic 'punched out' lesions. Metastases: Nonspecific lytic lesion which may have aggressive or non-aggressive features. finding of lytic bone lesion on imaging prompted further investigations. When a narrow zone of transition exists between normal bone and lytic tumor, the lesion typically takes form, or has a defined shape. Myeloma bone disease (MBD) lesions can present as discrete lytic lesions (radiolucent plasmacytomas) or as widespread osteopenias, multiple lytic lesions predominantly affecting the skull, spine, pelvis, ribs and sternum. compared multidetector row CT with conventional radiography and MR imaging in patients with newly diagnosed multiple myeloma [ 16 ]. Other histology. CONCLUSION. unexplained anaemia •Hypercalcemia •Renal failure SPB myeloma. The range of possibilities may also be influenced by the location of the primary tumor. Radiographically, bone lesions in RDD can be small and lytic, with sharply or poorly defined borders, or large with mixed lytic and sclerotic components that have cortical involvement, periosteal reaction, or soft tissue extension. A single metastatic lesion of plasma cell origin is termed a plasmacytoma. F: fibrous dysplasia; E: eosinophilic granuloma. In a 61-year-old patient with multiple lytic bone lesions, as in the presented case, malignancy is the first concern, and includes multiple myeloma, metastatic disease, or hemangioma in the top differential diagnosis. differential diagnoses. The presence of focal lesions of the vertebrae is highly suspicious of advanced malignancy. 2018-02-01. periapical cyst) or a lytic process (e. Differential Diagnosis. X-ray shows a permeative lytic lesion (arrowheads), cortial saucerization (black arrows), and calcifications within a soft-tissue mass (white arrow). Lateral view of the distal radius. This developmental disorder of bone can affect one bone (monostotic form), multiple bone (polyostotic form) or may occur in combination with. Stojanovic, N. The differential diagnosis remains broad and includes traumatic, vascular, infectious, neoplastic, met-abolic, and developmental causes. periapical (radicular) cyst (60% of odontogenic cystic lesions 4) periapical abscess. Read this post for a differential diagnosis for a cavitating lung mass. Diagnosis of 'brown tumor' is often challenging clinically and, hence, a high index of suspicion is essential to make a diagnosis. These can be either localized within or adjacent to the rib, but may also cause rib alteration as a component of a systemic process. The term permeative implies a lesion with a wide zone of transition and multiple small lytic areas within it. They may be identified as palpable masses or as incidental findings in radiological studies. The differential diagnosis includes brown tumors of hyperparathyroidism, which can appear radiologically and histologically identical to giant cell reparative cysts. In many other cases the lesion is visible due to destruction of cortex, or the presence of visible sclerosis. The presence of focal lesions of the vertebrae is highly suspicious of advanced malignancy. Common differential diagnosis includes: osteoma, osteosarcoma, chondroma. More common in males and African Americans. These lytic lesions in the distal femurs with calcified, serpiginous borders are typical of bone infarcts. See full list on ajronline. tularensis suppresses the immune response of host cells and intracellularly proliferates. CONCLUSION. However, some patients had features of both diseases. Metastatic carcinoma. Mahnken et al. periapical (radicular) cyst (60% of odontogenic cystic lesions 4) periapical abscess. Differential diagnosis of an aggressive lytic lesion in a 2-year-old child includes: – Osteomyelitis – Ewing’s sarcoma – Langerhans cell histiocytosis. Lytic lesions of the skull include a wide range of diseases, ranging from benign conditions such as arachnoid granulations or vascular lacunae, to aggressive malignant lesions such as lymphomas or metastases. 16/837,600, filed Apr. The bone scan was performed to evaluate extent of disease. AGE To evaluate a bone lesion it is of extreme importance to know the patient's age since certain tumors have a predilection for specific age groups. Minimal criteria for the diagnosis of MM include a bone marrow containing more than 10% plasma cells or histologic proof of a plasmacytoma, plus at least one of the following: an M-protein in the serum (usually > 3 g/dL), an M-protein in the urine, or lytic bone lesions. Given this patient's age, the differential diagnosis should be directed toward lymphoma, Paget's disease, and multiple myeloma. See full list on medcrine. application S. The differential diagnosis of the cause of lesions in one isolated cranial vault from this sample is presented here. Young patient with a lobulated lytic lesion within the anterior cortical bone of the proximal tibia. fibrous cortical defect. Roentgen Diagnosis of Diseases of Bone 3rd 3rd Baltimore, Md, USA Williams & Wilkins 25 Resnick D. Occasionally, the differential between a bone infarct and an enchondroma can be difficult on plain films; however, in this example, infarcts are easily diagnosed. Chronic nonbacterial osteomyelitis (CNO) is a focal sterile inflammatory osteitis in children that most commonly develops in the long bones, but can occur in any bone. These are mainly benign bone tumors that also manifest with bone pain and swelling. Rheumatoid arthritis. Today's Daily Diff concerns lucent bone lesions, which are commonly encountered incidentally when evaluating plain x-rays, especially of long bones. Whenever multiple, fluorodeoxyglucose-avid bone lesions are found, malignancy and metabolic bone disease should both be included in the differential diagnosis. Multiple myeloma is uncommon in the pediatric population, and prior cases suggest a milder clinical presentation vs that of adults. In plain radiographs with multiple lytic, bony lesions, contemplate round cell tumors of bone, particularly multiple myeloma and lymphoma. Bone sarcoidosis (k, l) CT (k) and T2WI (l): Mixed predominantly lytic multiple lesions with lace-like internal pattern of calcification and T2 hypointensity (dashed arrows). Epub 2021 Feb 16. Although a mixed pattern with lytic and blastic lesions is due to metastatic tumour, this is not the only possible origin. The differential diagnosis of clival and spinal tumors is vast and includes a variety of neoplastic and nonneoplastic lesions. , the lesion's pattern of bone destruction and lesion margins and the presence of any matrix mineralization, periosteal reaction, or soft tissue component. Osteoblastic, Osteolytic. More common than primary bone tumors (∼ 70% of all malignant bone tumors) Bones are the third most common site of. The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. bone-forming tumors. • Seen in patients between 10-20 years of age. While they’re usually harmless, they can occasionally be cancerous. II plus b, c, or d. 54 The identification of osteoid osteoma as a separate entity came later in a 1935 report by Jaffe. , bizarre parosteal osteochondromatous proliferation, fracture callus) or soft tissue lesions adherent to the bone surface (e. Multiple myeloma must be included in the differential diagnosis of any lytic bone lesion, either well-defined or ill-defined in age > 40. Diagnosis: C. Most common presentation: multiple lytic 'punched out' lesions. Plasmacytoma/multiple myeloma and lymphoproliferative. In conclusion, we report a case of sepin-linked CGL type 2 showing multiple bone lytic and pseudo-osteopoikilosis lesions limited to the hands and feet with typical clinical and laboratory features. In fact, the findings derived from xâ ? ?rays allow formulation of a reasonable hypothesis regarding the histological nature and possible differential diagnosis of a lesion. Differential diagnosis of cystic angiomatosis pre- senting as multiple lytic bone lesions. Of these, four exhibited multiple sites of blastic as well as lytic skeletal involvement on x-rays that were not detected by bone scans: two at the time of initial diagnosis, and two at relapse in children with prior radiotherapy to involved bones. A surgically transpedicular biopsy of the thoracic collapsed vertebrae. Lung Metastases – most common in the lower lung zones due to. Plasmacytoma/Myeloma Vikram Deshpande, MD G. Gamma globulin assessment defines the disorder as well. Multiple myeloma appears on X-rays as decreased bone density with a lot of "punched out" holes in the bone. 12688/f1000research. Clinical features The tumour occurs between 10 20 years of age The patient from MED 454 at Kendriya Vidyalaya, Pragati Vihar. Diagram of different types of bone tumors that can occur around the knee on XRay - Age > 30 years • Multiple Myeloma - punched out lesions. woman with a lytic femoral lesion. Fibrous lesions. These can be either localized within or adjacent to the rib, but may also cause rib alteration as a component of a systemic process. More than 2000 radiographs and schematic diagrams help to guide the reader toward the most likely diagnoses; The third edition of Differential Diagnosis in Conventional Radiology contains an updated and revised section on radiology of the abdomen combined with the complete text from the recently published books Bone and Joint Disorders and The. Diagnosis of 'brown tumor' is often challenging clinically and, hence, a high index of suspicion is essential to make a diagnosis. Our patient had a expansile lytic lesion with cavities with no fluid in the cavities. Discriminator: Must be over age 40. These studies showed multiple lytic lesions in bone, including the L5 vertebral body, and left sacrum, ilium, and proximal femur (Figures 1, 2, 3, and 4). The following case shows a systematic. Multiple myeloma must be included in the differential diagnosis of any lytic bone lesion, whether well-defined or ill-defined in age > 40; The most common location is in the axial skeleton (spine, skull, pelvis and ribs) and in the diaphysis of long bones (femur and humerus) Most common presentation: multiple lytic 'punched out' lesions. Lytic bone lesions are frequently encountered in a general radiology practice. Most scalp and skull lesions in children are benign. Based on these observations, we encouraged the oncologist to conduct an osteomedullary biopsy, allowing us to make a diagnosis of low-grade stage II lambda light chain multiple myeloma. Keywords: Secondary peripheral chondrosarcoma, periosteal chondrosarcoma, parosteal osteosarcoma, periosteal osteosarcoma, high-grade surface osteosarcoma INTRODUCTION Primary malignant tumors of the bone surface are a group of osteogenic and chondrogenic neoplasms with. In children and adolescents with multiple bone lesions and lytic lesion, one of the differential diagnoses that should be considered is CRMO. Lytic or blastic, well defined or poorly circumscribed margins Treatment. Lytic skull lesions have a relatively wide differential that can be narrowed, by considering if there are more than one lesion and whether the mandible is involved. All bone lesions can be described by the following parameters: 1. Full-body positron emission tomography/computed tomography imaging to assess for lymphoma and other occult inflammatory processes was also obtained. Abnormalities of bone and calcium metabolism are encountered in a substan-tial number of patients, although primary skeletal. lytic lesions which is the local disappearance of normal bone due to resorption skull - punched out holes what are the clinical manifestations of multiple myeloma. Bone tumors are mostly benign. Metastatic origins associated with lytic rib lesions commonly include the lung, breast, thyroid and kidney. Myeloma bone disease can cause the bones to become thinner and weaker (osteoporosis), and it can make holes appear in the bone (lytic lesions).
