Abstract: Squamous cell carcinoma (SCC) is the most common malignant oral neoplasm in cats, characterized by locally invasive behavior, rapid progression, and a poor prognosis. This report describes the clinical course of an 11-year-old mixed-breed domestic cat presented with a 15-day history of dysphagia and ptyalism associated with the development of an oral mass. On examination, a sessile, irregular, and necrotic lesion was observed on the left mandible. The initial incisional biopsy yielded a nonspecific diagnosis, requiring a second sample, which confirmed an undifferentiated SCC. As the owner declined specific treatment, only supportive therapy was instituted. After 30 days, marked tumor progression and clinical deterioration were noted, leading to the decision for euthanasia. This case highlights the importance of early diagnosis and the inclusion of SCC among the differential diagnoses in cats presenting with rapidly progressing oral masses.
