title: [Clinical aspects of ovary tumors in mares].
abstract: The present study comprises 31 mares, that showed a permanent unilateral enlargement of the ovary. In 29 patients the ovary in question was removed by a flanc laparotomy in the standing animal. In the histopathologic examination a granulosa cell tumor was diagnosed in 23 cases, a fibroma twice and a teratoma, hematoma, leiomyoma and a cystic ovary each once. Due to the endocrine activity of the granulosa cell tumor, the clinical picture was characterized by changed behaviour and atrophy of the contralateral ovary. Clinically the ovarial blastomas (teratoma, leiomyoma, fibroma) could not be differentiated from granulosa cell tumors. The postoperative prognosis of fertility is good. It should be noted though, that most of the mares did not foal until two years after the surgery.
