Desafio clínico e histológico no diagnóstico diferencial de alopecia difusa: Alopecia androgenética, eflúvio telógeno e alopecia areata, parte II

Abstract

Diffuse alopecia is mainly caused by telogen effluvium, diffuse androgenetic alopecia (femalepattern hair loss) and diffuse alopecia areata. Differential diagnosis between the three disorders may be difficult in several occasions. In this second part of our study, chronic telogen effluvium and diffuse alopecia areata are discussed in detail, including clinical, dermoscopic and histological aspects. A flowchart presents a practical and objective differential diagnostic approach to diffuse alopecia. © 2012 by Anais Brasileiros de Dermatologia.
