Focal dermal hypoplasia symdrome in a male.

Focal dermal hypoplasia (Goltz syndrome) is characterized by a pathognomonic abnormality of the skin in association with other congenital defects. There are only seven males among the 52 reported cases. We report the eighth case in a male and evaluate the possible genetic origin of the syndrome. A critical review of the literature provides no evidence for the previously accepted single gene mode of inheritance.
