[Femoral hypoplasia--unusual facies syndrome].

We report a new case of femoral hypoplasia-unusual facies syndrome (FH-UFS). A review of the literature disclosed fifty-five previously published cases. Both boys and girls can be affected. The syndrome includes bilateral femoral hypoplasia; facial dysmorphism with a cleft palate, micrognathia, a long philtrum, a thin upper lip, and a short broad-tipped nose; dysplasia of the hips; and hypoplasia of the fibulae. Other malformations may be found, including skeletal defects and visceral (especially cardiovascular and genitourinary) abnormalities. Etiopathogenesis of this syndrome remains unknown. Some investigators have suggested a link between the FH-UFS and caudal dysplasia in infants born to diabetic mothers.
