Treatment of Acquired Perforating Dermatosis: Perforating Folliculitis with Follicular Papules and Keratotic Plug

This protocol addresses acquired perforating dermatosis presenting specifically as perforating folliculitis — a distinctive subtype characterised by follicular papules with a keratotic plug. The scenario applies to patients where this eruption is not occurring in the context of molecular-targeted drug (kinase inhibitor) treatment.

Perforating folliculitis is a recognised form of acquired perforating dermatosis first described by Mehregan and Coskey in 1968. The eruption is characterised by follicular papules bearing a central keratotic plug, reflecting the transepidermal elimination process that defines this group of perforating disorders. Accurate identification of this specific presentation is important for directing appropriate management.
