[Frontal fibrosing alopecia (FFA): Report on four cases and review of the literature].

Frontal fibrosing alopecia was recently described by Kossard, et al. as a progressive symmetrical recession of the frontal-temporal-parietal hairline affecting particularly postmenopausal women. Besides affecting the scalp, there are some cases in the literature with partial or total loss of the eyebrows, also involving the trunk, and superior extremities. Because the clinical, histological, and immunochemical findings are indistinguishable from those seen in lichen planopilaris, frontal fibrosing alopecia is now considered a localized variant of lichen planopilaris. We report four cases of Mexican postmenopausal women with this kind of dermatosis evaluated at the Dermatological Center Dr. Ladislao de la Pascua.
