Smooth muscle cell tumors of the large bowel excluding the rectum are extremely rare. The case of a 30-year-old patient, who had ulcerative colitis for 5 years, is reported. Because of uncontrollable bleeding a proctocolectomy was performed. Along the whole colon the authors found more than 50 polypous tumors with a diameter up to 5 cm. Histologically all of these tumors were classified as leiomyosarcomas. The authors believe this to be the first reported case of multicentric leiomyosarcoma of the colon and of such a tumor associated with a history of ulcerative colitis.
排除直肠的大肠平滑肌细胞瘤极为罕见。本文报告了一名30岁、患溃疡性结肠炎5年的患者的病例。由于出血无法控制，遂行直肠结肠切除术。作者在整个结肠发现了50多个直径达5厘米的息肉状肿瘤。组织学上，所有这些肿瘤均被归类为平滑肌肉瘤。作者认为这是首例关于结肠多中心平滑肌肉瘤以及与溃疡性结肠炎病史相关的此类肿瘤的报道病例。
