Mucosa-associated lymphoid tissue has been reported throughout the gastrointestinal tract including rectum. Rarely, a nodular proliferation of predominantly submucosal lymphoid tissue in the rectum has been documented as rectal tonsil. Here we report a patient with HPV-associated squamous cell carcinoma of the rectal tonsil, presenting as a polyp. Previously, rare reports of HPV-associated lymphoepithelial carcinoma have been reported in the literature. We are presenting an extremely rare occurrence and emphasizing the importance of appropriate nomenclature based on the pathogenesis of the neoplasm.
黏膜相关淋巴组织已被报道存在于整个胃肠道，包括直肠。罕见情况下，直肠黏膜下淋巴组织的结节性增生也被记录为直肠扁桃体。我们在此报告一例 HPV 相关的直肠扁桃体鳞状细胞癌，表现为息肉样病变。此前，文献中已有少数 HPV 相关的淋巴上皮癌的报道。我们呈现了一个极其罕见的病例，并强调了根据肿瘤发生机制进行适当命名的重要性。
