Abstract:
Onychoheterotopia is a rare condition characterized by ectopic nail tissue growth. It is a digital mass that is commonly misdiagnosed. We describe a 6-year-old girl who presented with onychoheterotopia after trauma to the digit. Her onychoheterotopia was incorrectly diagnosed as a common wart. It is important to include onychoheterotopia in the differential diagnosis of digital masses, especially in the setting of previous traumatic injury.
