Abstract:
Trichorhinophalangeal syndrome (TRPS) is a rare genodermatosis with growth retardation, craniofacial abnormalities, alopecia and brachyphalangia. Three subtypes with considerable clinical overlap can be separated. Numerous nail changes have been documented in this syndrome. We observed a 19-year-old female with typical TRPS I who developed unique V-shaped longitudinal nail dystrophies on both hands. TRPS belongs to the spectrum of ectodermal dysplasias, and therefore it is not surprising that cutaneous adnexal structures are involved in different ways.
