Folliculitis decalvans (FD) is a neutrophilic scarring alopecia with peripheral spreading alopecic patches with pustules, crusting and tufted hair. Frontal fibrosing alopecia (FFA) is a lymphocyte-mediated primary cicatricial alopecia that affects frontal hairline and eyebrows. We report a 27-year-old black male presenting scarring alopecia with symmetrical retreat of the frontal and temporal borders of the hair implantation and eyebrow thinning. Skin biopsy revealed compact orthokeratosis, corneal plugs, regular acanthosis, superficial and deep perivascular and periadnexal inflammatory infiltrate, that was compatible with FD. We present a case of FD with retreat of hair line implantation and thinning of the eyebrows, as it is seen in FFA.
