title: Adnexal displacement and regression in association with histiocytoma (dermatofibroma).
abstract: The literature about the changes occurring in histiocytomas mentions only the possibility of induction of primitive pilosebaceous structures and basal cell epithelioma-like lesions by the histiofibrocytic growth. We suggest here that the histopathologic findings are indicative of regressive changes of the pre-existing cutaneous adnexa resulting in the formation of basal cell epithelioma-like structures.
