Case 1, a 44?year?old woman, presented with progressive recession of the frontotemporal hairline for 4 years and multiple skin?colored facial papules for 2 years. Skin examination showed that the frontotemporal hairline was receded, the local skin was smooth and thin, and a few remaining fine hairs could be seen. Additionally, eyebrows, axillary and pubic hairs were partly shed, and plenty of millet?sized skin?colored papules were diffusedly distributed on the frontotemporal region and bilateral mandibular angles. Dermatoscopy showed reduced hair follicular openings, different hair shaft diameters, cicatricial white patches and perifollicular erythema. Case 2, a 55?year?old woman, presented with progressive frontotemporal hair loss for 2 years. Skin examination revealed the recession of bilateral frontotemporal hairline and partial loss of eyebrows, axillary and pubic hairs. Histopathological examinations of the 2 patients both revealed perifollicular infiltration of lymphocytes, liquefaction degeneration of basal cells and perifollicular lamellar fibrosis. Clinical manifestations and histopathological features of the 2 patients both confirmed the diagnosis of FFA.
