Mesenteric leiomyosarcoma occurs most commonly in middle-aged individuals. Primary tumors of the mesentery are uncommon in pediatric and adolescent patients, and primary mesenteric leiomyosarcoma is particularly rare. Accurate preoperative diagnosis of mesenteric soft tumor is generally difficult. We describe a case of leiomyosarcoma arising from the ileal mesentery in a 13-year-old boy. The diagnosis was based on histopathologic evaluation using immunohistochemical staining and gene analysis.
肠系膜平滑肌肉瘤最常见于中年个体。肠系膜的原发性肿瘤在儿科和青少年患者中并不常见，而原发性肠系膜平滑肌肉瘤则更为罕见。准确的术前诊断肠系膜软组织肿瘤通常较为困难。我们描述了一例 13 岁男孩发生于回肠系膜的平滑肌肉瘤。该诊断基于组织病理学评估，包括免疫组织化学染色和基因分析。
