Leiomyomas are benign smooth muscle tumors predominantly found in the uterine wall, with rare occurrences in the gastrointestinal tract. Here, we report a rare case of a leiomyoma that was incidentally found in the rectum of an asymptomatic male who underwent a routine screening colonoscopy. Histopathological examination confirmed the diagnosis of leiomyoma. This case emphasizes the significance of routine colonoscopic screenings in the early detection of asymptomatic colorectal lesions and the pivotal role of Immunohistochemistry in differentiating rectal leiomyomas from other mesenchymal neoplasms, guiding appropriate management strategies.
平滑肌瘤是主要发生于子宫壁的良性平滑肌肿瘤，在胃肠道中罕见。在此，我们报告一例罕见病例，一名无症状男性在接受常规结肠镜筛查时，偶然在直肠发现平滑肌瘤。组织病理学检查确诊为平滑肌瘤。该病例强调了常规结肠镜筛查在无症状结直肠病变早期检测中的重要性，以及免疫组织化学在鉴别直肠平滑肌瘤与其他间叶性肿瘤、指导适当治疗策略方面的关键作用。
