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..'' in 1968 on the basis of the most unusual anomaly, the popliteal pterygium (a web behind the knee). == Clinical features == Clinical expressions of PPS are highly variable, but include the following:〔(medterms.com )〕 * Limb findings: an extensive web running from behind the knee down to the heel (90%), malformed toenails, and webbed toes. * Facial findings: cleft palate with or without cleft lip (75%), pits in the lower lip (40%), and fibrous bands in the mouth known as syngnathia (25%). * Genital findings (50%): hypoplasia of the labia majora, malformation of the scrotum, and cryptorchidism. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Popliteal pterygium syndrome」の詳細全文を読む スポンサード リンク
