Perda pilosa por líquen plano pilar após transplante capilar: Relato de dois casos e revisão da literatura

Abstract

Androgenetic alopecia is often treated by follicular unit transplantation, a technique that involves minimal risk of hair loss because of the more resistant nature of the donor area. Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor areas. The quality of the hair follicles in the donor area was apparently compromised by lichen planopi-laris, the probable cause of hair loss. Similar reports are rare. When lichen planopilaris is suspected, a biopsy of the scalp must be performed to avoid transplantation during disease activity. © 2011 by Anais Brasileiros de Dermatologia.
