Abstract
目的:探讨浅表性平滑肌肉瘤(superficial leiomyosarcoma,SLMS)的临床病理特点、诊断、鉴别诊断及治疗和预后.方法:回顾性分析13例SLMS的临床病理特征,并复习相关文献讨论.结果:男7例,女6例,平均年龄59岁.肿瘤位于四肢7例,躯干3例,头面部2例,阴囊1例,其中位于真皮的9例,皮下4例.肿瘤直径1~8(平均4.3)cm.局部复发5例,无远处转移病例.镜下:肿瘤呈结节状或弥漫状生长,根据肿瘤细胞不同分化分为三型:中分化(最多见,9例)、高分化和低分化型(较少,各2例).免疫组织化学:肿瘤细胞desmin,MSA,a-SMA和h-caldesmon阳性.结论:SLMS多发生于中老年人,预后较好,易发生局部复发,极少发生远处转移.治疗采用局部扩大切除.
