title: Juvenile xanthogranuloma underneath a toenail.
abstract: A 1 1/2-year-old boy developed a dystrophic toenail shortly after trauma to the foot. At the age of three years, it was recognized that the nail deformity was caused by a subungual tumor. The tumor proved to be a juvenile xanthogranuloma. The lesion was solitary, and no systemic associations or visceral involvement were found.
