Gynecologists need to be cognizant of extra-ovarian pathology in the atypical presentation of a pelvic mass. Correct diagnosis is essential for proper management since GISTs specifically respond to the c-kit selective tyrosine kinase inhibitor, Imatinib mesylate.
Within the spectrum of extratesticular mesenchymal tumors in the scrotum and perineum lies cellular angiofibroma, also known as angiomyofibroblastoma-like tumor, a rare lesion originally described to almost exclusively occur in the vulva, perineum, and pelvis of women. We report a case of this tumor, with an adjacent scrotal lipoma, occurring in a 60-year-old male who presented to our department with a firm palpable scrotal mass. To our knowledge, the MRI findings of this entity have yet to be described in the radiological literature. We present the MRI features of cellular angiofibroma that are consistent with the pathological characteristics of this entity-a benign cellular and fibrous tumor with prominent vascularity.
Synovial sarcomas are a distinct clinical entity occurring most often in the lower extremities. They account for 10–14% of all soft tissue sarcomas. Pulmonary synovial sarcomas are quite rare and account for less than 0.5% of all intra-thoracic neoplasms. We present the first reported case of primary pulmonary synovial sarcoma with intra cardiac extension in a 53-year-old male who presented with chronic cough. Imaging revealed a large right upper lobe mass extending through the superior pulmonary veins into the left atrium. The patient underwent a right total pneumonectomy with extraction of the left atrial mass and left atrial reconstruction. Pathology and immunohistochemistry was diagnostic of primary pulmonary synovial sarcoma positive for SYT-SSX1 gene fusion transcription.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
