[Partial hydatidiform mole in Morocco: an epidemiological and clinical study]

This retrospective study reviewed cases of partial hydatidiform mole (PHM) diagnosed at the University Hospital in Casablanca from 2000 to 2010 in order to examine the epidemiological, clinical, therapeutic and progressive pathological factors associated with PHM. All PHM cases confirmed clinically and sonographically at pathological examination were included. We identified 24 cases of PHM among 60 748 births and 1704 abortions, giving a frequency of 0.4 per 1000 pregnancies and 1.4% of abortions. The mean age was 26 years (range: 16-55 years). The circumstances of discovery and clinical ultrasound varied: 79.2% of patients sought consultation for bleeding; clinical thyrotoxicosis syndrome was found in 1 patient (4.2%). Physical examination showed increased uterine size in 83.3% of cases associated with a latero-uterine mass in 25%. The diagnosis was supported by an ultrasound examination combined with measurement of plasma betaHCG. Histological confirmation was made in all cases and treatment was endo-uterine aspiration. Neoplastic drift was observed in 1 case (4.2%) which went into remission with chemotherapy.
