Dotted Pigmentation of the Cuticle.

Longitudinal melanonychia in children is usually caused by nail matrix nevi and often fades over time. Pediatric patients with this finding are frequently referred to dermatologists due to concerns that it may represent melanoma. We report a case of a 4-year-old girl with longitudinal melanonychia on the left second fingernail, accompanied by pigmented dots in the cuticle that persisted after the melanonychia had faded.
