Abstract

Ultrastructual observations on an unusual gonadal stromal tumor of the testis in a 4-year-old boy with gynecomastia revealed that the tumor cells lacked the abundant smooth endoplasmic reticulum usually found in neoplastic and nonneoplastic Sertoli and Leydig cells. The cells were rich in cytoplasmic microfilaments, with localized dense areas of the type seen in smooth muscle cells as well as intracytoplasmic lipid droplets. It is concluded that the tumor cells show important similarities to the immature fusiform interstitial cells and the peritubular contractile cells present in the normal testis.

摘要

对一名患有男性乳房发育症的4岁男孩睾丸中一种不寻常的性腺间质肿瘤进行超微结构观察发现,肿瘤细胞缺乏通常在肿瘤性和非肿瘤性支持细胞及间质细胞中发现的丰富滑面内质网。细胞富含细胞质微丝,有平滑肌细胞中所见类型的局部致密区以及胞质内脂滴。得出的结论是,肿瘤细胞与正常睾丸中存在的未成熟梭形间质细胞和管周收缩细胞有重要相似之处。
