A 9-year-old girl presented with a complaint of a dark-colored lesion over her forehead since birth associated with thick hair. There was no history of seizures, and general and systemic examination was unremarkable. Cutaneous examination revealed a hyperpigmented mamillated plaque of size 10 cm × 8 cm associated with overlying thick coarse terminal hair present over the left forehead extending between the left eyebrow down to the left frontoparietal region without crossing the midline [Figures 1 and 2]. There was no evidence of ulceration, bleeding or nodularity. Based on history and clinical findings, a final diagnosis of segmental hairy nevus (congenital melanocytic nevus) was made. Parents were counseled about the prognosis of the nevus, and she was referred to a plastic surgeon for surgical excision.
