Uterine smooth muscle tumors range from benign leiomyomata to low- and high-grade leiomyosarcomas. A leiomyosarcoma is a rare malignant smooth muscle tumor that infrequently metastasizes to the bone. In fact, initial presentation or recurrence as osseous metastases is extremely uncommon in patients with a history of leiomyosarcoma. On imaging, these bone lesions generally appear as lytic foci. ...
RANULOMATOUS LESIONS have been found iii paraffin sections nlade from particles of bone marrow removed by aspiration from patients w’it-h tuberculosis, histoplasmosis, brucehlosis, sarcoidosis, infectious mononucleosis, malignant lymphomas or miscellaneous and indeterminate disorders.19 In a previous paper,4 I discussed the significance of granulomatous lesions foiits(l in sections made from bo...
Osteolytic lesions seen on plain radiographs can be caused by various disorders of the bones such as simple bone cyst, aneurysmal bone cyst, plasmacytoma, giant cell tumor, eosinophilic granuloma and tuberculosis. We studied prospectively Tc-99m-methylene diphosphonate bone scan findings in osteolytic lesions seen radiologically and followed them to histopathology. Interestingly, the scans in t...

Multiple myeloma (MM) originates from malignant plasma cells, leading to multiple destructive lytic bone lesions that occur in more than 80% of MM patients. MicroRNAs have been reported to be involved in development of bone lesions in MM. However, the circulating microRNA as diagnostic and prognostic biomarkers for bone lesions has not been elucidated yet. In this study, we identified different...
Background: Bone tumors are infrequently encountered disease constituting only 0.5% of the total world cancer incidence. There worldwide variations in different bone lesion and patterns cancer. Histologic evaluation is one first prerequisites evaluating any primary tumor. Methods: The present study was carried out at Gauhati Medical College hospital (GMCH), Guwahati, Assam for a period 2 years....
Jugular foramen schwannomas are a rare event with an estimated 200 cases reported in the literature. These tumors represent only 2.9% to 4% of all intracranial and less than 1% temporal bone lesions [1,2].
Modic et al. in 1988 first described characteristic MRI changes in the vertebral body bone marrow and endplates, adjacent to degenerating intervertebral (iv) discs. Depending on the changes in T1 and T2 MRI signals, three types of lesions were identified: Type I lesions (low T1 and high T2 signal) are thought to be clinically active, due to increased blood flow within the bone. Type II lesions ...
BACKGROUND/AIM Bone bruise is a common finding in acutely injured knee examined by magnetic resonance (MR). The aim of the study was to determine the association of bone bruise frequency with postinjury lesions of anterior cruciate ligament (ACL) and menisci. Bone bruise involves posttraumatic bone marrow change with hemorrhages, edema and microtrabecular fractures without disruption of adjacen...
Introduction: Ostoid osteoma is a benign bone tumor characterized by pain especially at night, which is relieved with aspirin. Hand is an uncommon site of this tumor. Here a case of ostoid osteoma in middle phalanx is reported. Case Report: The patient of the present case study was a 26-year-old woman referred due to a pain in her left ring finger. The diagnosis was made pre-operatively thr...
