Vitiligo-Like Patches due to Epidermal Interface Changes in Frontal Fibrosing Alopecia: Further Evidence of Non-Follicular Involvement

Abstract

Coelho TOA, Romiti R, Valente NS and Donati A

Frontal Fibrosing Alopecia (FFA) is a primary cicatricial alopecia that presents with alopecia over the frontal hairline. Skin involvement in FFA was first acknowledged in 2012 when the association between FFA and Lichen Planus (LP) pigmentosus was described. Here we present a Caucasian FFA female patient with vitiligo-like patches over the front and neck whose biopsy showed epidermal interface changes. This is the first time achromic lesions due to interface dermatitis are associated to FFA, adding evidence for the extra-follicular epithelial involvement of the disease. True vitiligo, as well as subacute lupus erythematosus, are differential diagnoses that must be excluded.
