Solitary fibrofolliculoma.

We present a case of solitary fibrofolliculoma. Histopathologic findings of this entity are characteristic: in the dermis a central hair follicle is surrounded by a thick mantle of fibrotic and mucinous stroma, and numerous thin, anastomosing bands of follicular epithelium extend into this stroma. This entity has been described as occurring only multiply; to our knowledge, this is the first case report of a solitary fibrofolliculoma.
