Endometrial Stromal Sarcoma Arising in Colorectal Endometriosis: A Case Report and Review of the Literature

الملخص EN

Extrauterine endometrial stromal sarcoma (ESS) arising in endometriosis is extremely rare, particularly in the colorectum.

It should always be included in the differential diagnosis of primary tumors originating from gastrointestinal tract in females, given that preoperative endoscopical biopsy may reveal no specific changes.

We reported a case of ESS arising in colorectal endometriosis and reviewed the previous 7 cases reported in the English literature.

Our patient, who was unavailable for tumor resection and refused further adjuvant therapy, played a role in representing the natural history of low-grade extragenital ESS.

This case was the only death from ESS arising in colorectal endometriosis.
