Abstract
Introduction
The Spitz nevus (SN) is an acquired melanocytic neoplasm composed of epithelioid and/or spindle cells, which tends to develop in childhood. In pediatric patients, it is usually located on the face and neck. Unusual locations have been found in the literature, such as the penis, mouth, and tongue, as well as 2 cases of ungual SN.
Case Report
A 15-year-old male evaluated for dark brown-black longitudinal melanonychia that covered 40% of the nail, with pseudo-Hutchinson's sign, of 1 year of evolution.
Discussion
The SN accounts for 1% of the melanocytic neoplasms. In the present paper, we show the third case of ungual SN never previously disclosed, which presents a zigzag pattern reported in the literature for its association with the pediatric population.
