The gastrointestinal tract is the most common site of extra-nodal non-Hodgkin lymphoma. However, the incidence of primary rectal lymphoma is extremely rare. Among the primary gastrointestinal lymphomas, follicular lymphoma has been described as a rare disease. It is difficult to diagnose rectal lymphoma due to its variable growth patterns and inadequate biopsies. Majority of patients with rectal lymphoma have non-specific symptoms or negative biopsies, often delaying the diagnosis. Our patient is a 62-year-old female. Two sessile and smooth subepithelial lesions with a yellowish normal mucosa were found on a screening colonoscopy. The initial mucosal biopsy finding was chronic inflammation, but we were highly suspicion of malignancy; we performed an endoscopic mucosal resection. Herein, we present a rare case of rectal follicular lymphoma diagnosed by endoscopic mucosal resection with a literature review.
胃肠道是结外非霍奇金淋巴瘤最常见的发病部位。然而，原发性直肠淋巴瘤的发病率极其罕见。在原发性胃肠道淋巴瘤中，滤泡性淋巴瘤被描述为一种罕见疾病。由于直肠淋巴瘤生长方式多样且活检不足，难以对其进行诊断。大多数直肠淋巴瘤患者有非特异性症状或活检结果为阴性，常导致诊断延迟。我们的患者是一名62岁女性。在结肠镜筛查中发现两个无蒂、表面光滑的黏膜下病变，黏膜呈淡黄色，外观正常。最初的黏膜活检结果为慢性炎症，但我们高度怀疑为恶性肿瘤；于是进行了内镜黏膜切除术。在此，我们报告一例经内镜黏膜切除术诊断的罕见直肠滤泡性淋巴瘤病例，并进行文献复习。
