溃疡性结肠炎（UC）与结直肠癌风险增加有关。然而，非上皮性恶性肿瘤的发生是罕见的。在一名有30年UC病史的51岁女性中发现降结肠病变升高。尽管肿瘤进展，重复活检显示没有癌性发现。由于病变高度怀疑是恶性肿瘤，因此进行了部分结肠切除术。病理诊断为平滑肌肉瘤。胃肠道平滑肌肉瘤是罕见的，这只是第三个已知的病例报告的UC患者。
Ulcerative colitis (UC) is known to be associated with an increased risk of colorectal cancer. However, the occurrence of non-epithelial malignancies is uncommon. An elevated lesion in the descending colon was found in a 51-year-old woman with a 30-year history of UC. Despite tumor progression, repeated biopsies showed no cancerous findings. Because the lesion was highly suspected to be a malignant tumor, a partial colectomy was performed. The pathological diagnosis was leiomyosarcoma. Leiomyosarcoma of the gastrointestinal tract is rare, and this is only the third known case reported in patients with UC.
