Leiomyomas in the colon are uncommon accounting for a few cases of gastrointestinal smooth muscle tumors. These tumors are usually benign and asymptomatic. They may present with abdominal pain, intestinal obstruction, perforation, and rarely hemorrhagic, especially when the tumor is large. We present the case of a sigmoid leiomyoma in a 60-year-old patient consulting for a positive fecal occult blood test. Colonic leiomyomas should be considered in the differential diagnosis when a polyp is found during routine endoscopic evaluations. This case also highlights the limitations of diagnosing the nature of polyps using endoscopy alone.
结肠平滑肌瘤并不常见，仅占胃肠道平滑肌肿瘤的少数病例。这些肿瘤通常为良性且无症状。它们可能表现为腹痛、肠梗阻、穿孔，很少出现出血，尤其是当肿瘤较大时。我们报告一例60岁患者因粪便潜血试验阳性前来咨询，其患有乙状结肠平滑肌瘤。在常规内镜检查发现息肉时，鉴别诊断应考虑结肠平滑肌瘤。该病例还凸显了仅通过内镜检查诊断息肉性质的局限性。
