title: Hormone producing ovarian tumours in the dog.
abstract: In two cases of granulosa cell tumours of the ovary in bitches there was production of sex hormones by the neoplasm. Both tumours produced oestrogens but one also produced significant concentrations of progesterone. In both bitches, the presenting sign was abnormally prolonged oestrus activity. One dog also developed a haemorrhagic diathesis as a result of endogenous oestrogen toxicity.
