Gastrointestinal stromal tumour (GIST) is a rare tumour of gastrointestinal tract, comprising of 0.1-3.0% of all gastrointestinal malignancies. They are commonly found in stomach (60-70%), very rarely in rectum and anal canal (<5%). The present case report is of a large anorectal leiomyoma (142×80mm) arising from posterior rectal wall, with its unusual presentation of urinary retention. In our case, in view of its massive size, recurrence and malignant transformation, we planned abdominoperineal resection. Although size and histological grade play an important role, complete resection still is considered the most significant favorable prognostic factor.
胃肠道间质瘤（GIST）是一种罕见的胃肠道肿瘤，占所有胃肠道恶性肿瘤的0.1%-3.0%。它们常见于胃（60%-70%），很少见于直肠和肛管（<5%）。本病例报告的是一例起源于直肠后壁的巨大肛管直肠平滑肌瘤（142×80mm），伴有尿潴留这一不寻常表现。在我们的病例中，鉴于其巨大的尺寸、复发及恶变情况，我们计划行腹会阴联合切除术。尽管肿瘤大小和组织学分级起着重要作用，但完整切除仍被认为是最重要的有利预后因素。
