Leiomyomas are rare, benign tumors composed of smooth muscle cells. When found in the colon, they account for only about 3% of gastrointestinal leiomyomas. Typically asymptomatic, they are often incidentally discovered during endoscopic evaluations. This report describes the case of a 71-year-old female with abdominal pain and distension, whose colonoscopy revealed a 7 mm sessile polyp in the sigmoid colon. Histological analysis confirmed it to be a submucosal leiomyoma. Although endoscopic resection is a common therapeutic strategy, surgical treatment may be necessary for larger tumors or when malignancy is suspected. This case emphasizes the limitations of polyp classification through endoscopy alone and the important role histopathological analysis continues to play in this regard. Accurately diagnosing these lesions is crucial for appropriate treatment and surveillance, namely, in the primary healthcare context. Further research is needed to improve diagnostic capabilities and reduce the need for repeat colonoscopies, reducing patient burden.
平滑肌瘤是由平滑肌细胞组成的罕见良性肿瘤。当在结肠中发现时，它们仅占胃肠道平滑肌瘤的约3%。通常无症状，常在内镜检查时偶然发现。本报告描述了一名71岁腹痛腹胀女性的病例，其结肠镜检查发现乙状结肠有一个7毫米的无蒂息肉。组织学分析证实为黏膜下平滑肌瘤。虽然内镜切除是一种常见的治疗策略，但对于较大的肿瘤或怀疑有恶性病变时可能需要手术治疗。该病例强调了仅通过内镜进行息肉分类的局限性以及组织病理学分析在这方面继续发挥的重要作用。准确诊断这些病变对于适当的治疗和监测至关重要，即在初级医疗保健环境中。需要进一步研究以提高诊断能力并减少重复结肠镜检查的必要性，减轻患者负担。
