Popliteal pterygium syndrome

Abstract

Popliteal pterygium syndrome (PPS), also termed as popliteal web syndrome or facio-genito-popliteal syndrome, is an autosomal dominant disorder that affects the development of face, limbs, and genitalia. The term PPS was coined by Gorlin, et al in 1968, on the basis of the most unusual anomaly, the popliteal pterygium (a web behind the knee). The disorder is very rare, occurring in <1 in 10,000 individuals.
