A 76-year-old female was noted to have a rectal mass on evaluation for postmenopausal bleeding. There was no history of abdominal pain, constipation, or rectal bleeding. Flexible sigmoidoscopy revealed a 3-cm pedunculated rectal mass at 10 cm. Hair fibers were visible through the smooth glistening surface. At colonoscopy, the polyp was removed by snare polypectomy. Histology showed epidermal, mesodermal, and endodermal components diagnostic of benign cystic teratoma. Subsequent total abdominal hysterectomy and bilateral salpingo-oophorectomy revealed endometrial carcinoma and postmenopausal ovaries. Primary rectal teratoma is a very rare rectal mass that may present endoscopically. Since 1865, only 33 cases have been reported in the literature. Endoscopic photographs, histology, and a review of the literature are presented.
一名76岁女性因绝经后出血接受检查时发现直肠肿物。无腹痛、便秘或直肠出血病史。乙状结肠镜检查发现距肛缘10 cm处有一个3 cm带蒂直肠肿物。透过光滑闪亮的表面可见毛发纤维。结肠镜检查时，通过圈套息肉切除术切除了息肉。组织学检查显示有表皮、中胚层和内胚层成分，诊断为良性囊性畸胎瘤。随后的全腹子宫切除术和双侧输卵管卵巢切除术发现了子宫内膜癌和绝经后卵巢。原发性直肠畸胎瘤是一种非常罕见的直肠肿物，可通过内镜检查发现。自1865年以来，文献中仅报道了33例。本文展示了内镜照片、组织学检查结果并对文献进行了综述。
