The formation of structures resembling hair matrices is the least common form of follicular differentiation and only occurs with any frequency in pilomatricoma. Rarely, follicular cysts and both benign and malignant adnexal tumors can show areas of pilomatricoma-like change, or hair matrix differentiation. Examples of focal hair matrix differentiation in a follicular cyst, a cutaneous mixed tumor, and an adnexal carcinoma are presented. Each of these cases also demonstrates the presence of limited differentiation toward structures of the inner root sheath.
类似毛母质的结构形成是毛囊分化最不常见的形式，仅在毛发瘤中经常出现。很少有毛囊囊肿以及良性和恶性附属器肿瘤可显示毛发瘤样改变区域或毛母质分化。本文展示了毛囊囊肿、皮肤混合瘤和附属器癌中局灶性毛母质分化的实例。这些病例均显示出对内毛根鞘结构的有限分化。
