A case of multiple skeletal anomalies, ectodermal dysplasia, and severe growth and mental retardation.
A 17-year-old female patient presented extreme growth failure, severe microcephaly and developmental delay, and a unique pattern of congenital anomalies, predominantly of the skeleton and the skin. Prominent findings included hidrotic ectodermal dysplasia with virtually complete absence of body hair, ichthyosiform hyperkeratosis of the skin over the lower legs, dysplasia of toenails; small hands and feet with with short fifth fingers and toes complete cutaneous syndactyly between toes 4 and 5; in X-rays, fusion of several vertebral bodies, humero-radial ankylosis, fusion between talus and navicular bone, lunate and triquetral, and proximal fusion between metacarpals 4 and 5; and luxation of the right femoral head. The patient might represent a hitherto undescribed malformation syndrome of unknown etiology.
