Pruritus and hyperplacentosis.

Hyperplacentosis refers to the maternal manifestations of increased placental activity, such as elevated human chorionic gonadotropin, theca luteal cysts, preeclampsia, and/or pruritus. Six cases of apparent hyperplacentosis were diagnosed in the third trimester because of maternal complaints of pruritus. The association of maternal or fetal complications with hyperplacentosis is described.
