Abstract

Background and objectives: Cicatricial alopecia is a group of uncommon disorders of the hair follicle with many causes that can lead to hair destruction of either primary or secondary causes. Trichoscopy is a quick and non-invasive tool that help to establish diagnosis of different types of cicatricial alopecia. The aim of the study was to assess the dermoscopic features of various cicatricial alopecias.

Methods: Twenty-five patients were included in this study with various types of cicatricial alopecias. Full history and examination was done for all patients. Dermoscopic examination was done for all patients but histopathological examination was done for the patients that required confirmation of the diagnosis when necessary by Hematoxylin and Eosin stain.

Results: The result of this study dermoscopically revealed that 12 patients had lichen planopilaris (48.0%), 6 had discoid lupus erythematosus (24.0%), 6 had dissecting cellulitis (24.0%) and one patient had pseudopelade of Brocq (4.0%). Absence of follicular opening was a constant dermoscopic feature in all types of cicatricial alopecia participated in this study. Perifollicular erythema was noticed in 72.0% of patients. Enlarged branching vessel was present in 68.0%, followed by peripilar cast, hair tufting, keratotic plug and blue-gray dots represented by 52.0%, 48.0%, 48.0%, and (48.0%), respectively.

Conclusions: Scalp Trichoscopy is a useful method to help establish the diagnosis of various cicatricial alopecia, yet histopathological examination remains the core diagnostic test.
