Tırnak yatağı dışında farklı bir lokalizasyonda gelişmesi ile karakterizedir. Bir bayan hastada eşlik eden kemik anomalisi, ektodermik sendrom ya da travma olmaksızın gelişen ektopik tırnak olgusu sunuyoruz. ABSTRACT Ectopic nail is an extremely rare disorder related to acquired or congenital anomalies. It is characterized by the growth of nail-like tissue in a location other than the nail bed. We present a case of spontaneous growth of ectopic nail on the finger of a female patient without bone anomalies or associated ectodermic syndromes and trauma.
