Disease of the trophoblast.

Molar pregnancy should always be considered as a possible diagnosis in any pregnancy that does not conform to the normal. The practice of subjecting all pregnant women to ultrasound B-scan at their first visit in some centres is commendable, but unfortunately not possible in the areas of high incidence, owing to lack of facilities. Close, regular and meticulous follow-up with facilities for radio-immunoassay of HCG is a necessity after a mole has been treated. Early detection of lesions and individualized treatment of patients, with close monitoring of progress, are essential. Where necessary, enlightened use of drugs with adjuvant surgery and occasionally radiotherapy will give the optimum chance of recovery. To achieve complete eradication of the tumour, treatment may be required even after the HCG test appears to be negative.
