Follicular Psoriasis - A Forgotten Entity?

Abstract

Follicular psoriasis is a common yet under reported entity. Major dermatology textbooks fail to emphasise and even neglect this important diagnosis and since its original description in 1920 there have been only three reports in the published literature. As a result the diagnosis is seldom entertained by dermatology trainees in the differential diagnosis of a folliculocentric skin disease. We present a case of follicular psoriasis which was initially mis-diagnosed as lichen planopilaris and summarise the key features of this neglected entity. Our aim is to highlight awareness of this disorder and we also propose that the follicular variant be included as a psoriasis subtype in standard dermatology textbooks.
