“…During this period there have been nearly 100,000 deliveries and 79,500 gynaecological operations. Javert and Finn (1951), Hughesdon and Fraser ( 1953 ), Pedowitz and O'Brien (1960), Foster (1962), O'Hern and Neubecker (1962) and Novak and Long (1963) have reviewed the literature and added cases of their own. It appears, from the above reviews, that only about 250 authentic cases have been reported since Pick (1905), first described a non-virilising tumour and Bell (1915) one with similar histological features and virilisation.…”
