A case of a 6-month-old male with a peripheral pigmented neuroectodermal tumor of the right popliteal region is presented. The tumor disclosed neuroblast-like and melanoblast-like cells and on electron microscopy tumor cells with rhabdomyoblastic differentiation. The patient is well and alive and without evidence of disease three years after the initial diagnosis. This unusual case gives further support to the current theory of a common origin for central and peripheral neuroectodermal neoplasms and related entities.
本文报告一例6个月大男性，其右腘窝区患有外周色素性神经外胚层肿瘤。肿瘤显示出神经母细胞样和黑素母细胞样细胞，电子显微镜检查发现肿瘤细胞有横纹肌母细胞分化。初次诊断三年后，该患者情况良好，无疾病迹象。这一罕见病例进一步支持了目前关于中枢和外周神经外胚层肿瘤及相关实体具有共同起源的理论。
