Folliculitis Decalvans and Lichen Planopilaris Phenotypic Spectrum: A Case Report

Abstract

The folliculitis decalvans (FD) and lichen planopilaris (LPP) phenotypic spectrum combines biphasic features of FD and LPP. It is characterized by successive or concomitant occurrence of pustules, crusts, follicular tufts, perifollicular erythema, perifollicular scales, and cicatricial alopecia and includes mixed histologic features of both FD and LPP. Here, we report the case of a 33-year-old female patient with a 30-year history of FD-LPP phenotypic spectrum lesions.
