Abstract
Abstract Background: Ovarian granulosa cell tumors (GCTs) are common neoplasms in domestic animals that originate from the sex-cord stromal cells of the ovary. The aim of the present paper was to report a case of ovarian GCT in a 5-year-old Persian female cat and to describe the histopathological pattern of this tumor. Case Description: The cat was brought for a routine diagnostic examination for pregnancy at Albaittar clinic in Tripoli, Libya with a history of 1 month mating before it was brought to the clinic for investigation of progressive behavioral changes. The cat external examination showed noticeable enlargement in the abdomen that was potentially suspected of pregnancy; however, the abdominal ultrasonography showed a great mass located on the right ovary. A therapeutic ovariohysterectomy was performed. The cat’s clinical signs resolved, 6 months later it was diagnosed with a mass on the right kidney suspected as metastasis and one week later the cat died. Conclusion: In this case, macroscopic and microscopic studies are discussed and histopathological examination confirmed ovarian GCT with cystic endometrial hyperplasia and suspected metastasis in one kidney.
