Pruritic urticarial papules and plaques of pregnancy (PUPPP), known in United Kingdom as polymorphic eruption of pregnancy (PEP), is a chronic hives-like rash that strikes some women during pregnancy. Although extremely annoying for its sufferers (because of the itch), it presents no long-term risk for either the mother or unborn child. PUPPP frequently begins on the abdomen and spreads to the legs, feet, arms, chest, and neck. Papules and plaques usually start appearing on the abdomen (although not on the umbilicus/bellybutton) and often spreads to the legs, chest, underarms, etc. The face is usually also spared and does not seem to become affected. Skin distension (stretching) is a common factor in PUPPP, which is more common in mothers with large fundal measurements and/or those who are carrying large babies, twins, and triplets. The papules and plaques often first appear within stretch marks. Certain studies reveal that this condition is more frequent in women carrying boys, although no formal research has been conducted. Statistics cite that 70% of PUPPP sufferers deliver boys. Some researchers think it has to do with male DNA interacting with the mother's body causing irritation. PUPPP's occurs in about 1 in every 200 pregnancies and is not always easy to diagnose. http://www.whatispupps.com/PUPPSFACTS.html Image:PUPPP_2007-05-06_front2.jpg|Front view of abdomen Image:PUPPP-abdomen.jpg|Side view of abdomen Image:PUPPP-feet.jpg|Feet and ankle view ==Cause== The cause of the condition is generally unknown,.〔 There is a correlation between the PUPPP rash and dairy. When some women stop drinking dairy the rash has been known to go away. This skin condition occurs mostly in first pregnancies (primigravida), in the third trimester and is more likely with multiple pregnancies (more so with triplets than twins or singletons).〔Pruritic Urticarial Papules and Plaques of Pregnancy 〕 Other than additional associations with hypertension and induction of labour, there are no observed difference in the outcome of the pregnancy for mothers or babies. 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「pruritic urticarial papules and plaques of pregnancy」の詳細全文を読む スポンサード リンク
