Plain-English summary
An 8-month-old Scottish Fold cat was brought to the vet with a swollen belly, trouble breathing, pale gums, and low energy. An ultrasound showed a mass in her liver that looked like several cysts. The vet performed surgery to remove the mass, which was found to be a vascular hamartoma, a type of abnormal blood vessel growth. After the surgery, the cat's symptoms improved, and she was diagnosed with a rare condition that had not been previously reported in cats.

Abstract
Vascular hamartomas represent a focal proliferation of disorganized vascular tissue, which is usually present at birth. An 8-month-old Scottish fold female cat presented with abdominal distention, mild dyspnea, pale mucous membranes, and lethargy. Ultrasound examination revealed a hepatic mass resembling multiple cysts affecting the right medial lobe. Surgical excision was performed, and tissue samples were sent for histopathological evaluation. The mass was composed of multiple, dilated, variably-sized well-differentiated arterioles and venules, consistent with vascular hamartoma. Immunohistochemical investigation of the cells lining the cystic structures showed positive immunolabeling for vimentin and negative immunolabeling for PanCK, supporting the histological diagnosis. Based on existing literature, this represents the first case of hepatic localization of vascular hamartoma in a cat. In addition, a comparative histological study between vascular hamartoma and biliary duct hamartoma and a review on hepatic vascular hamartomas in animals and hepatic cystic masses in cats was made.
