Vet. Pathol. 26:121-128 (1989) Feline Oral Neoplasia: A Ten-Year Survey

Abstract. A retrospective histological study was conducted on 37 1 neoplasms of the oral cavity in cats. Oral neoplasia accounted for 10 % of feline neoplasms identified during the survey period. Eighty-nine percent of the oral neoplasms were malignant. Twenty different oral neoplasms were found. The most common were squamous cell carcinoma (6 1.2%), fibrosarcoma (1 2.9%), and fibromatous epulis of periodontal ligament origin (7.8%). Neoplasms arising in the oral cavity of cats are rel-atively common. Previous reports suggest that neo-plasms of the oral cavity comprise approximately 3-12 % of all feline neoplasms.lX5J3 The most common feline oral neoplasms are squamous cell carcinoma1+ 6 ~ 1 2 ~ 1 3 and fibro~arcorna.~,~, ~ This is in contrast to the dog, in which periodontal epulides and melanomas are the most frequently reported oral neoplasm^.^^^. ^ In this study we present data on oral neoplastic masses in-cluding incidence rates and characterization of peri-odontal epulides and odontogenic neoplasms
