An adnexal tumor on the scalp of a 74-year-old woman is described. Histologically, the tumor was composed of cystic structures showing typical trichilemmal keratinization. The tumor cells in the cyst walls often formed duct-like or squamous eddy-like structures and occasionally showed vacuolation or poroma-like change. Ultrastructurally, some tumor cells showed differentiation either toward the acrosyringium or sebaceous cells. From these findings, the present tumor is considered to differentiate toward various parts of the hair follicle including infundibulo-isthmus epithelium, apocrine acrosyringium, and sebaceous cells.
本文描述了一名74岁女性头皮上的附件肿瘤。组织学上，肿瘤由显示典型毛鞘角化的囊性结构组成。囊壁中的肿瘤细胞常形成导管样或鳞状漩涡样结构，偶尔可见空泡化或汗孔瘤样改变。超微结构上，一些肿瘤细胞显示出向顶泌汗腺导管或皮脂腺细胞分化。基于这些发现，目前的肿瘤被认为可向毛囊的各个部分分化，包括漏斗部-峡部上皮、顶泌汗腺导管和皮脂腺细胞。
