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.
本研究包括31匹母马，这些母马表现出卵巢永久性单侧肿大。29例中，相关卵巢在站立的动物身上通过侧腹剖腹术切除。组织病理学检查诊断出23例颗粒细胞瘤，2例纤维瘤，畸胎瘤、血肿、平滑肌瘤和囊性卵巢各1例。由于颗粒细胞瘤的内分泌活性，临床表现为行为改变和对侧卵巢萎缩。临床上，卵巢母细胞瘤（畸胎瘤、平滑肌瘤、纤维瘤）无法与颗粒细胞瘤区分开来。术后生育预后良好。不过应该注意的是，大多数母马直到手术后两年才产驹。
