Complete molar pregnancy

• Complete moles have a 46XX karyotype - caused by a single sperm fertilising an anucleate oocyte then duplicating its genetic material

• Secrete large quantities of HCG


• Characterised by hydropic avascular villi with a snow-storm appearance on ultrasound scan


• The alpha subunit of HCG is identical to the alpha subunit of TSH and high levels of HCG may cause symptomatic hyperthyroidism
