TLDR A 16-year-old boy had a rare case of Becker's nevus on his face and mouth.
Becker’s nevus, also known as Becker’s pigmented hairy nevus, is a common melanotic epidermal hypermelanosis typically presenting as a large unilateral patch of hyperpigmentation and hypertrichosis on the shoulder, chest, or back of adult men. This report described a rare case of a 16-year-old boy with two Becker’s nevi on the left side of his face in a segmental distribution, extending onto the oral mucosa. This unusual presentation highlighted the potential for Becker’s nevi to appear in atypical locations and configurations.
