Fibrosing Alopecia in a Pattern Distribution: A Case Report and Literature Review

Abstract

© 2019 The Author(s). Published by S. Karger AG, Basel. Fibrosing alopecia in a pattern distribution (FAPD) is a relatively new entity in the family of cicatricial alopecia. It has been categorized as a member of the lichen planopilaris (LPP) group due to its similarity in clinical and histopathological presentation. Nonetheless, the disease earns its own entity due to its lichenoid inflammation exclusively involving miniaturized hair and area of involvement mimicking pattern hair loss which differentiates itself from other types of LPP or pattern hair loss. Since its first introduction by Zinkernagel and Trüeb in 2000, there have been only few case reports and series of FAPD. We herein report a case of FAPD in a postmenopausal woman who had progressive hair loss over the course of 10 years.
