Abstract

Squamous cell carcinoma (SCC) is a malignant epithelial neoplasm formed from keratinocytes, accounting for 60 to 73% of the most common oral malignant tumors in felines. Its etiology is multifactorial and not fully elucidated; however, previous non-malignant lesions, consumption of canned products, and chronic exposure to ultraviolet light predispose its development. The sublingual and lingual regions, maxilla, mandible, oral mucosa, lip, and the pharyngeal region are the sites most frequently affected by oral SCC. The presumptive diagnosis is made through cytological analysis and confirmed by histological evaluation, with imaging being essential for classifying the location of the lesion and the extent of bone involvement. The present study aimed to describe the radiographic, cytopathological, and histopathological findings of a domestic feline, of no defined breed, six years old, that presented oral squamous cell carcinoma with intense bone involvement.
