What is popliteal pterygium syndrome?
Popliteal pterygium syndrome. Popliteal pterygium syndrome (PPS) is an inherited condition affecting the face, limbs, and genitalia. The syndrome goes by a number of names including the popliteal web syndrome and, more inclusively, the facio-genito-popliteal syndrome. The term PPS was coined by Gorlin et al..
What is the pathophysiology of pterygium?
It is primarily characterized by the presence of pterygia (or wings) present in two or more body areas overlying predominantly the large joints. Accompanying joint contractures are almost always present. The majority of cases carry an autosomal recessive inheritance while a small proportion of cases may carry an X-linked recessive inheritance.
What are the signs and symptoms of pterygia?
It is characterized by minor facial abnormalities, prenatal growth deficiency, spine defects, joint contractures, and webbing (pterygia) of the neck, elbows, back of the knees, armpits, and fingers. [1] Fetuses with this condition are usually not born.
