We have found eight granulosa tumours in nine years out of 280 ovarian tumours which were collected in the maternity and neonatology unit in Rabta. The mean age of the patients was 53, the mean parity was 8. Signs of oestrogen excretion were found in all cases and metrorrhagia was the principal reason for consulting doctors in 75% of cases. There was always a palpable mass on clinical examination. Histology was usually only microfollicular. Radical surgical treatment was carried out in all cases and consisted of total abdominal hysterectomy and bilateral salpingo-oophorectomy.
