[Nail diseases as a symptom of ectodermal dysplasia and related syndromes].

The nails are often involved in complex dysplasias. The present paper reviews nail manifestations of complex dysplasias, ectrodactylia and selected palmoplantar keratoses with associated symptoms. Some of these are of early diagnostic importance, while others are rare symptoms of complex dysplasias. Mono- and oligosymptomatic syndromes are drawn to the reader's attention.
