A case of pure aquamous carcinoma of the rectum is presented, and the literature reviewed. Squamous carcinomas of the colorectum are rare tumours which have clinicopathological features in common with adenocarcinomas. Evidence is presented to support the proposal that most tumours of the large intestine that consist partly or completely of squamous elements arise from areas of squamous differentiation in pre-existing adenomas. The pathogenesis of squamous carcinoma and adenosquamous carcinoma appears to be similar to that of adenocarcinoma.
本文报告一例直肠纯鳞状细胞癌病例，并对相关文献进行综述。结直肠鳞状细胞癌是罕见肿瘤，具有与腺癌相同的临床病理特征。现有证据支持以下观点：大多数部分或完全由鳞状成分组成的大肠肿瘤起源于先前存在的腺瘤中的鳞状分化区域。鳞状细胞癌和腺鳞癌的发病机制似乎与腺癌相似。
