Solitary rectal ulcer syndrome (SRUS) is a benign and chronic disorder well known in young adults that is characterized by a series of symptoms such as rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, a feeling of incomplete defecation, constipation and, rarely, rectal prolapse. The etiology of this syndrome remains obscure, and the diagnosis is easily confused with that of other diseases, contributing to difficulties in treatment. We present a case of a 37-year-old male with a nonulcerated rectal lesion grossly resembling a superficial depressed rectal cancer misdiagnosed in another hospital and describe its appearance on endoscopy and in the analysis of its pathological manifestations. The aim of this case report is to report an easily misdiagnosed case of SRUS, which needs to be distinguished from superficial rectal cancer, which should be educational for endoscopists.
孤立性直肠溃疡综合征（SRUS）是一种良性且慢性的疾病，常见于年轻人，其特征是一系列症状，如直肠出血、大量黏液排出、长时间过度用力、会阴部和腹部疼痛、排便不尽感、便秘，以及罕见的直肠脱垂。该综合征的病因仍不清楚，诊断容易与其他疾病混淆，导致治疗困难。我们报告了一例 37 岁男性，其直肠非溃疡性病变大体上类似于表浅凹陷型直肠癌，曾被另一所医院误诊，并描述了其在内镜下和病理表现上的特征。本病例报告的目的是报告一例容易误诊的 SRUS 病例，需要与表浅性直肠癌相鉴别，这对内镜医生应具有教育意义。
