<unk>  (or mola<unk> a) is a common complication of pregnancy, it consists of a nonviable embryo which implants and proliferates within the uterus.  The term is derived from<unk>  ("like a bunch of grapes") and mole (from Latin mola = millstone).
Most moles present with painless vaginal bleeding during the second trimester of pregnancy. They are diagnosed by ultrasound imaging. Extremely high levels of human chorionic gonadotropin (HCG) are suggestive, but not diagnostic, of molar pregnancy.<unk> s are surgically removed by curettage, in order to avoid the risks of choriocarcinoma.
