Synovial sarcoma is a rare soft tissue sarcoma that typically arises in the extremities of young adults. We report a case of a 26-year-old pregnant woman with biopsy-proven primary synovial sarcoma of the lung that was treated with chemotherapy with radiographic response. This is only the third documented case of primary pulmonary synovial sarcoma occurring during pregnancy and the first case w...

INTRODUCTION Jejuno-jejunal invagination is a rare condition and is usually caused by a benign lesion. We describe the case of a patient with a jejunal epithelioid sarcoma. Epithelioid sarcoma is a rare histologic subtype of sarcoma and few cases have been published. CASE PRESENTATION A 70-year-old Caucasian man presented with vomiting and anemia. A jejuno-jejunal invagination was diagnosed a...

Sarcomas are a broad family of mesenchymal malignancies exhibiting remarkable histologic diversity. We describe the multi-platform molecular landscape of 206 adult soft tissue sarcomas representing 6 major types. Along with novel insights into the biology of individual sarcoma types, we report three overarching findings: (1) unlike most epithelial malignancies, these sarcomas (excepting synovia...

Evaluation of the primary spindle cell sarcoma prostate, which is seen extremely rare, is aimed.

BACKGROUND In musculoskeletal sarcomas, brain metastases are rare, but severely affect quality of life. METHODS All patients with musculoskeletal sarcomas who were treated at our institutions from 1975 to 1997 were reviewed for examples of brain metastasis. RESULTS Of 480 sarcoma patients, 179 had distant metastases, including 20 patients with brain metastases (4.2%). Alveolar soft part sar...

Fewer than 40 cases of primary pleural synovial sarcoma have been reported so far with only 3 cases of cystic synovial sarcoma including cases originating from sites other than the pleura. Here, we present an exceedingly rare case of cystic synovial sarcoma originating from the mediastinal side of the visceral pleura in a 25-year man presenting with hemoptysis. On contrast-enhanced computed tom...

Primary pleuropulmonary synovial sarcoma is a rare malignancy. Commonly described radiologic features in the literature include pleural disease and/or effusion, lack of calcification and high uptake on positron emission tomography computerised tomography. A 68-year-old woman presented with a 3-month history of cough. Imaging studies showed a right upper lobe mass with internal foci of calcifica...
