摘　　要：目的探讨非砂粒体型黑色索性神经鞘瘤（NPMS）的临床病理特点、诊断及鉴别诊断要点。提高病理医生对NPMS的认识及诊断水平。方法应用HE染色对1例发生于骶管的NPMS进行组织形态学观察，并复习相关文献。结果光镜下NPMS由长形及卵圆形上皮样瘤细胞组成，多数瘤细胞胞质内可见黑色素颗粒并将细胞核掩盖。肿．但无坏死，未见病理性核分裂象。结论NPMS是一种罕见的周围神经肿瘤，具有特征性的组织病理学特点 ，易与其他含有色素的软组织肿瘤混淆。多数NPMS为良性，少数病例会恶变．术后应长期随访复查。Objectives To investigate the clinicopathological features, diagnosis and di[ferentiat diagnosis of nonpsammomatous melanotic sehwannoma（NPMS）, and to improve its diagnostic level. Methods The features of histopathology were observed by means of HE stains in 1 case of NPMS as well as literature review. Results Micro- scopically, NPMS was composed of [usiform shape and oval epithelioid tumor cells, the melanin granule was found in most tumor cells which covered up the nucleus of the tumor cells. Tumor cystic degeneration was found, but the necrosis and pathological mitotic figure wasn＇t observed. Conclusions NPMS is a rare peripheral nerve tumor, charaeterized by distinctive histopathological features and often confused with other pigment soft tumors. Although most of the NPMS are benign, a few have the potential of malignant change. The long-term follow-up should be stressed after operation.
