Plain-English summary
A 3-year-old female domestic shorthair cat was taken to the vet because her owner noticed a lump in her belly, along with signs of not eating and being unusually quiet for about a month. Tests on the lump suggested it might be a tumor or a liver issue, but surgery revealed it was actually an ovarian luteoma, a type of tumor from the ovary. After the surgery to remove the mass, the cat's condition improved, and she was able to recover well.

Abstract
A 3-year-old intact female domestic shorthair cat was presented for the evaluation of a palpable intra-abdominal mass in the left caudal abdomen. The cat had a history of anorexia, depression and prolonged estrus over a period of about 1 month. Smears prepared from a fine needle aspirate of the mass revealed large round to oval cells arranged individually or in loose clusters surrounded by pink, fibrillar matrix material. Cytoplasm was basophilic, with many variably-sized vacuoles and variable numbers of small purple granules. The vacuoles within the cells were strongly positive with Oil-Red-O stain. The cytologic features were most suggestive of a neoplasm of epithelial cell origin or inadvertent aspiration of a fatty liver. At laparotomy, the mass was found to involve the left ovary. Histologically, the tumor consisted of dense sheets and nests of irregular polyhedral, pleomorphic cells with abundant, finely vesiculated cytoplasm. The tumor cells were separated into lobules by strands of connective tissue. Based on histologic evaluation, a diagnosis of ovarian luteoma was made. In this report, we document the cytologic and histologic features of an uncommon feline tumor, a luteoma, and address its possible misdiagnosis as hepatic lipidosis when using cytology alone to make a diagnosis.
