Isolated leg hair involvement in lichen planopilaris

Lichen planopilaris (LPP) is the follicular representation of lichen planus which is the prototype of CD8+ T cell mediated inflammatory diseases. In all the variants of LPP clinical hallmark is the scarring alopecia of involved hair follicles in which the scalp hair is the main target. Though the non-inflammatory type alopecia is documented in certain subtypes such as lassueur-graham-little-piccardi (LGLP) and frontal fibrosing cicatricial alopecia (FFA) where it particularly affects the body hair, scarring alopecia of body hair is extremely rare in LPP. Herein we report a case of isolated leg hair involvement in LPP.
