title: Long-term suppression of a testosterone-producing ovarian tumour by oestrogen/progestogen therapy.
abstract: A 44-year-old lady presenting with hirsutism was found to have a testosterone-secreting Leydig cell tumour of the right ovary. Serum testosterone levels were adequately suppressed for 8 years by combined oestrogen/progestogen preparation (Microgynon 30, Schering, West Sussex). The fall in gonadotrophin and testosterone levels during therapy and their rise after stopping therapy suggests that the tumour was gonadotrophin dependent.
