A 67-year-old postmenopausal lady presented with frontal scalp hair loss and loss of eyebrows of 1-year duration. Examination revealed frontal cicatricial alopecia with temporoparietal extension, peripheral perifollicular scaling, and eyebrow madarosis [Figure 1]. Polarized videodermoscopy (EScope; Nakoda, ×20) revealed honeycombing of the scalp skin and multiple white dots representing absence of follicular openings, follicular hyperkeratosis and plugging, perifollicular scaling, and erythema [Figure 2]. Cicatricial white patches were not seen. Some interfollicular scaling and erythema were present, suggestive of mild seborrheic dermatitis.{Figure 1}{Figure 2}

Few scattered yellow and several black dots were appreciable [Figure 2]. Miniaturized or vellus hairs were absent. Histopathology revealed perifollicular lymphocytic infiltrate, papillary dermal fibroplasia, and focal replacement of follicles with early fibrotic changes [Figure 3], confirming the diagnosis of active frontal fibrosing alopecia (FFA).{Figure 3}

FFA, a cicatricial alopecia typically encountered in post-menopausal women, is considered to be a distinct variant of lichen planopilaris.[1] Trichoscopy conveniently differentiates between the causes of alopecia of the scalp margin as FFA, alopecia areata (AA), traction alopecia, and cicatricial marginal alopecia (CMA).[2] While the trichoscopic features easily ruled out AA, lack of miniaturized hairs and fractured hair shafts excluded traction alopecia. The absence of follicular openings, absence of vellus hairs, presence of follicular hyperkeratosis and plugs, and perifollicular scales are dermoscopic hallmarks of FFA.[2],[3],[4] Absence of cicatricial white patches and presence of perifollicular erythema further suggest disease activity.[3],[4],[5] These typical dermoscopic features and the typical histopathology confidently ruled out CMA. Honeycombing of the scalp skin is a normal trichoscopic finding in the skin of color chronically exposed to sunlight. The most common trichoscopic features of FFA include absence of follicular openings, followed by follicular hyperkeratosis, perifollicular erythema, and follicular plugs.[3] In this case, we also observed the presence of few scattered yellow and several black dots, an inconsistent and uncommon feature of FFA.
