title: Keratotic horn on left fifth fingertip: congenital ectopic nail misdiagnosed as a common wart.
abstract: The term "ectopic nail" refers to nail tissue found in a location other than in the normal nail bed. Here we report a 9-year-old girl with an asymptomatic keratotic "horn" on the tip of her left fifth finger. Present since the age of 1 month, it was misdiagnosed as a common wart and treated using liquid nitrogen cryotherapy without benefit.
