Abstract

A 9-mm granular-cell myoblastoma of the cecum found incidentally during appendectomy in a 17-year-old-girl is reported. Electronmicroscopic findings favor origin of the granular cells from an undifferentiated mesenchymal (fibroblast-like) cell. Review of the small number of previously reported cases revealed three involving the cecum, one each in the ascending and transverse colon and two in the rectum. Four patients were asymptomatic and their lesions were found incidentally. Three lesions simulated maligancy clinically; these patients underwent right hemicolectomy.

摘要

报告了一名17岁女孩在阑尾切除术中偶然发现的盲肠9毫米颗粒细胞成肌细胞瘤。电子显微镜检查结果支持颗粒细胞起源于未分化的间充质（成纤维细胞样）细胞。对少数先前报道的病例进行回顾发现，其中3例累及盲肠，升结肠和横结肠各1例，直肠2例。4例患者无症状，其病变为偶然发现。3例病变在临床上疑似恶性；这些患者接受了右半结肠切除术。
