A 6 years old female Persian cat was presented with an oral tumor. A hemispherical mass, 18 mm in maximum diameter, without a peduncle and bright reddish in color, was observed on the gingive of the left mandible. Radiographic study shows osteolysis. The tumor was surgically removed via gingival incision around the margin to the depth of connective tissue layer. Histopathological examination indicated that the tumor contained a large number of neoplastic fibroblasts intermixed with vascular stroma and collagen tissue and was diagnosed as fibrornatous epulides with malignant characteristics. Tumor was recurred after 3 months. Due to lack of owner interest to treatment with chemotherapy agents and following his decision, the cat was euthanized with overdose injection of thiopental sodium.
