Femoral-facial syndrome in an infant of a diabetic mother.

Femoral-facial syndrome (FFS) is a very rare multiple congenital anomaly syndrome. The authors describe a case of FFS in a 2-day-old infant of a diabetic mother. The phenotypic features include bilateral symmetrical femoral involvement with completely aplastic right-sided femur, severely hypoplastic left femur and unusual facial dysmorphic features without other skeleton/spinal and genitourinary anomalies. Cases of FFS need to be carefully evaluated because of the similarity between FFS and caudal dysgenesis, a condition frequently related to maternal diabetes and with other syndromes characterised by femoral hypoplasia and associated anomalies, which can pose a diagnostic challenge. 2015 BMJ Publishing Group Ltd.
