Ovarian sex cord-stromal tumours in cattle, with particular reference to the lamination of basal laminae.
Three cases of bovine sex cord-stromal tumours, including a sex cord tumour with annular tubules and two granulosa cell tumours, are described. These tumours had tubular structures and hyaline or eosinophilic bodies, composed of multilayered basal laminae. The present study suggests that bovine granulosa cell tumours of the ovary are able to show morphology similar to that of Sertoli cell tumours of the testis and that sex cord tumours with annular tubules arise from granulosa cells but indicate Sertoli cell differentiation.
