Rectal tonsils are an abnormal reactive proliferation of lymphoid tissue in the rectum. Typical lymphoid tissue of the colon and rectum can proliferate with an increased number of germinal centers in response to exposure to an antigen in the GI tract. This response, in rare cases, escalates to the proliferation of a lymphoid mass known as a rectal tonsil. Here, we present a case of a 46-year-old woman with iron deficiency anemia who underwent colonoscopy with incidental finding of a rectal tonsil. This report discusses initial clinical workup, colonoscopy findings, pathological analysis, subsequent testing, and surgical removal of the identified mass and this rare finding.
直肠扁桃体是直肠内淋巴组织的异常反应性增生。结肠和直肠的典型淋巴组织可因暴露于胃肠道抗原而增殖，生发中心数量增加。在罕见情况下，这种反应会升级为一种称为直肠扁桃体的淋巴组织团块的增殖。在此，我们报告一例46岁缺铁性贫血女性患者，其在结肠镜检查时偶然发现直肠扁桃体。本报告讨论了初始临床检查、结肠镜检查结果、病理分析、后续检测以及对所发现肿块的手术切除和这一罕见发现。
