BMJ Case Rep. 2025 Jan 14;18(1):e261817. doi: 10.1136/bcr-2024-261817.

Abstract

Synovial sarcoma is a rare malignant mesenchymal tumour typically found in the extremities, but it can also develop in the gastrointestinal tract, with the upper rectum being the most common site. We describe a case of a man in his 60s diagnosed with monophasic synovial sarcoma in the lower rectum, presenting with severe, intractable anal pain.

Keywords: Cancer intervention; Colon cancer; Gastrointestinal surgery.
