Primary Cicatricial Alopecias
Refers to a group of rare, idiopathic, inflammatory scalp disorders that result in permanent hair loss. Cicatricial alopecias are traditionally classified by their inflammatory infiltrate (lymphocytic, neutrophilic, mixed). The inflammatory process affects mainly the upper portion of the follicle and is followed by a permanent destruction of the hair follicle. Primary cicatricial alopecia frequently starts on the central and parietal scalp before progressing to other sites of the scalp. A lack of follicular ostia is the hallmark of scaring alopecia. Crucial to the diagnosis if cicatricial alopecia is a detailed clinical history and one or two biopsy samples of an active lesion. The goal of any
scalp reduction surgery are possible once the lesions
are burnt out and stable. Graft survival may not be as good as in androgenetic alopecia and disease reactivation is possible at any time after surgery.
