Osteosarcoma is a relatively uncommon malignancy however, it is the most common form of primary malignant bone tumors in human. Diagnosis and prognosis of patients with osteosarcoma is limited to clinico-radiopathological parameters, whereas molecular markers of tumor aggression have been poorly identified. Survivin, an inhibitor of apoptosis (IAP), is unique for its expression in human tumors ...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

between i 9h i and 1993,30 cases of primary cardiac tumors were diagnosed at the imam khomeini hospital. 20 patients were female and 10 were male, with an average age of 32 years (ranging from 17 days to 65 years of age). the mean duration of symptoms before diagnosis was 6 months, with dyspnea and palpitation being the most common symptoms (60%) and cardiac' murmurs the most usual signs (...

Imaging plays a crucial role in the evaluation of primary bone tumors in adults. Initial radiographic evaluation is indicated in all cases with suspected primary bone tumors. Radiographs are useful for providing the diagnosis, a short list of differential diagnosis or at least indicating the degree of aggressiveness of the lesion. More detailed information about the lesion, such as cortical des...

ewing’s sarcoma is a round cell malignancy of bone and soft tissue that occurs predominately in adolescents and young adults.it is an uncommon malignancy, but is recognized as the second most prevalent primary bone tumor worldwide. extraosseous ewing’s sarcoma is extremely rare and can affect the skin, soft tissues, or viscera. prognostic and therapeutic features of ewing’s extraosseous tumors ...

The author studied 133, 856 admissions over a ten-year period and found 138 cases of primary tumors of bone. Of these only 33 were multiple myeloma. Incidence, clinical manifestation, age, sex and etiology are reported, and the effect of four different chemotherapy regimens are evaluated.
