title: [Case report of a granulosa-theca tumor in a cow].
abstract: A 2 year-old cow with abnormal behaviour was observed during a farm visit. Rectal palpation of the cow revealed the presence of a mass of at least 12 cm in diameter. After further examination, it appeared that 'ovarian tumour' was the most likely differential diagnosis. In order to confirm this diagnosis, blood samples were drawn and analysed for plasma progesterone and plasma oestradiol-17 beta concentrations. Also, the gross pathology and histology of the mass were evaluated. The combination of the clinical presentation of the cow, the hormone concentrations, and the histological appearance of the mass confirmed the diagnosis ovarian tumour. The tumour was classified as granulosa-theca cell tumour.
