Trichofolliculoma with Incidental Acantholytic Dyskeratosis

Authors: Larry D. Hudson, MD

Abstract

Bogle, Cohen, and Tschen have presented a new clinical association for the dermatopathologic changes of acantholytic dyskeratosis. This uncommon histologic marker is characteristic of Darier disease, but can also be seen in a number of other entities. 1


Trichofolliculomas are small, solitary tumors usually occurring on the face, but occasionally are seen on the scalp or neck. In some cases a small central pore is visible. If such a pore is visible, a fine tuft of white hair may be seen extending from the pore. This finding is characteristic of a trichofolliculoma. Otherwise, these solitary tumors may mimic basal cell carcinoma, nevi, and other dermal tumors.
