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.
发生于子宫内膜异位症的子宫外子宫内膜间质肉瘤（ESS）极为罕见，尤其是在结直肠部位。鉴于术前内镜活检可能未发现特异性改变，对于女性胃肠道原发性肿瘤的鉴别诊断，应始终将其纳入考虑范围。我们报告了1例发生于结直肠子宫内膜异位症的ESS病例，并回顾了英文文献中此前报道的7例病例。我们的患者无法进行肿瘤切除且拒绝进一步辅助治疗，这对于呈现低级别生殖器外ESS的自然病程起到了一定作用。该病例是结直肠子宫内膜异位症相关ESS导致死亡的唯一病例。
