Plate-like sebaceous hyperplasia overlying dermatofibroma.

ABSTRACT

Epidermal hyperplasia, sometimes with primitive hair follicle-like differentiation, is a characteristic finding overlying dermatofibroma. We here report plate-like sebaceous hyperplasia overlying a dermatofibroma. Such changes are interpreted as a result of inductive epithelial effect by the dermatofibroma on the overlying epidermis.
