Follicular Becker's nevi: A case series and review of literature

Abstract

The follicular variant of Becker's nevus is an under‐reported entity. We present the rare occurrence of follicular Becker's nevus in 7 patients, confirmed through dermoscopy and histopathological examination. Dermoscopy shows perifollicular hypopigmentation surrounded by a well‐defined net‐like pigmentation corresponding clinically to the presence of folliculocentric macules. Histology shows prominent basal and suprabasal melanization surrounding the follicle, corresponding to well‐defined net‐like pigmentation seen on dermoscopy. However, the melanization does not extend along the entire length of the follicular epithelium leading to perifollicular hypopigmentation on dermoscopy. Though biopsy is confirmatory, it is not usually necessary.
