[McKusick-Kaufman syndrome in a new born girl (author's transl)].

In a newborn, the presence of an abdominal tumor due to hydrocolpos resulting from vaginal atresia, with polydactyly and a congenital heart disease suggest the diagnosis of McKusick-Kaufman syndrome. This syndrome is different from the Ellis Van Creveld syndrome, which also includes polydactyly and congenital heart disease, associated with "chondrodysplasia' and "ectodermodysplasia'.
