title: The first documented case of high-grade synovial cell sarcoma of the rectum.
abstract: A patient presented with signs and symptoms of tenesmus, urgency, and rectal bleeding that she had been experiencing over the course of several months. Full endoscopic evaluation showed a 6-cm submucosal mass approximately 10 cm from the dente line projecting as an endoluminal mass with a large broad base. An initial endoscopic resection was attempted but aborted because of significant hemorrhage, and surgical oncology was consulted. After stabilization, the patient underwent a transanal resection of the mass the following day. An endoscopic gastrointestinal anastomosis stapler resulted in a margin-negative complete resection of what was later determined to be a high-grade synovial cell sarcoma. This case report presents the first known documented case of synovial cell sarcoma of the rectum.
