Common name for Hydatidiform mole. It may exist as a "complete" or "partial" mole. The complete variety is diploid and has double the paternal complement of chromosomes, lacking any maternal chromosomal material, and has no recognizable fetal tissue. The partial variety is usally triploid, although it may be diploid as well. The partial mole has a recognizable but nonviable fetus.

A more detailed Hydatidiform mole w/u is planned.
