Cicatricial alopecia associated with pemphigus.

Pemphigus is a chronic autoimmune bullous disease associated with the production of autoantibodies directed against desmosomal proteins, such as desmogleins 1 and 3. Here, we present the case of an 83-year-old woman who was referred to us with suspicious cicatricial alopecia of the scalp and a small, eroded lesion on the forehead, previously labeled as atrophic actinic keratosis after a skin biopsy. In our clinic, after a careful examination of the case, we decided to perform two new skin biopsies of the scalp on suspicion of an inflammatory disease.
