[Prader-Labhart-Willi syndrome with precocious puberty. (author's transl)].

At least in boys hypogenitalism is a constant feature of the Prader-Labhart-Willi Syndrome. Our patient, a 16 10/12 years old girl had the characteristic symptoms of the syndrome and precocious puberty. Menarche had occurred at the age of 8 6/12 years. Precocious puberty does not exclude the diagnosis of a Prader-Labhart-Willi syndrome.
