Endometriosis is defined as the growth of functional endometriotic gland and stroma outside the uterine cavity. Although it is common in women of reproductive age, extragenital endometriosis is considerably rare. Due to its frequent localization at the rectosigmoid junction in the gastrointestinal system, endometriosis may manifest with abdominal pain, constipation, and rectal bleeding. Gastrointestinal stromal tumor is the most common mesenchymal tumor of the gastrointestinal system and develops from the muscularis propria. Its extraluminal component is prominent. This study aimed to report a rare case of a 37-year-old patient who was operated with laparoscopic colon resection for a malignant-appearing submucosal mass with indistinct borders at the rectosigmoid junction that received the final diagnosis in histopathological examination. Endometriosis should be considered in the differential diagnosis of non-specific gastrointestinal symptoms in female subjects of reproductive age as the one reported here.
子宫内膜异位症的定义是功能性子宫内膜腺体和间质在子宫腔外生长。虽然它在育龄女性中很常见，但生殖器外子宫内膜异位症相当罕见。由于其在胃肠道系统中常位于直肠乙状结肠交界处，子宫内膜异位症可能表现为腹痛、便秘和直肠出血。胃肠道间质瘤是胃肠道系统最常见的间叶性肿瘤，起源于固有肌层。其腔外成分突出。本研究旨在报告一例罕见病例，一名37岁患者因直肠乙状结肠交界处出现边界不清的疑似恶性黏膜下肿块接受了腹腔镜结肠切除术，组织病理学检查最终确诊。对于育龄期女性出现的非特异性胃肠道症状，如本文报道的病例，在鉴别诊断时应考虑子宫内膜异位症。
