[Brachyonychia of different types in a mother and daughter].

Different types of brachyonychia were observed in a mother and her daughter. The mother presented a unilateral racket thumb-nail (localized brachyonychia "en raquette" of Basset). In the case of the daughter the thumbs and three middle fingers of both hands were involved, the nails of the little fingers being normal (generalized brachyonychia "en raquette" of Basset). Also, the daughter's toe-nails were short and wide. There was a family history of short nails "on all fingers" occurring in the two sisters of the mother's father. We believe that localized and generalized types of racket nails are variants of the same inherited anomaly. As far as we know, this is the first report of brachyonychia of the toe-nails.
