Abstract
In soft tissues, malignant tumors with epithelial qualities are usually metastatic carcinomas. A rare, primary, soft tissue tumor that is uniformly carcinoma-like is the monophasic, glandular, synovial sarcoma. Three cases of [human] carcinoma-like neoplasms of soft tissue were studied. In 1 primary tumor and 2 recurrent tumors of soft tissue, the histologic patterns were uniformly glandular. For the 2 recurrent tumors, the primary lesions were a classic, synovial sarcoma and a biphasic, synovial sarcoma with a histiocytic, stromal component. By inference, the 3rd tumor, a primary carcinoma of soft tissue, may represent a de novo, monophasic, glandular, synovial sarcoma. Synovial sarcoma should be considered in the differential diagnosis of carcinoma-like tumors discovered in soft tissues.
