Double Nail of the Little Toe

Abstract

A rudimentary accessory or double nail of the little toe is not rare, although only described three times before. Most cases are accidentally detected and only few patients seek help because they have discomfort or pain. Some have a positive family history, but most patients cannot give any information concerning heredity. Clinically, the nail of the little toe is abnormally wide and is split or shows a longitudinal depression corresponding to a slight protuberance of the cuticle. Histopathology shows a complete though short nail. The treatment of choice is segmental excision of the entire accessory nail unit with mobilization of the lateral skin and primary suture.
