Abstract

Porokeratosis is a disorder of keratinization, characterized clinically by a peripheral keratotic ridge and histologically by the cornoid lamella. We describe a patient with follicular porokeratosis with a distinctive clinical presentation. We believe that follicular porokeratosis is a unique histopathologic variant of porokeratosis, with cornoid lamellae centered in follicular infundibula. Further, this is the only report of follicular porokeratosis involving the face exclusively.

Follicular porokeratosis at alae nasi; A case report and short review of literature

“…[5] There have been a few reports of exclusive facial involvement in porokeratosis, with skin lesions mostly over or near the nose. [1678910] Follicular involvement, identified by follicular localization of cornoid lamellae, is uncommon and described only in association with other subtypes such as DSAP, PM, and exclusive follicular cornoid lamella in follicular porokeratosis. [411]…”

“…On histopathologic examination solar elastosis was not shown, whereas, Wang at al showed solar elastosis histophatologically, different from our case. [9] While follicular porokeratosis is accepted as a distinct histopathologic entity in some publications, but it didn’t enter clinical classification.…”
