Squamous cell carcinoma (SCC) represents the most frequent tumor among all cancers of the oral cavity, with an average age of 60 years and greater occurrence in males. The classic characteristic of the lesion is a hardened nodule, with signs and symptoms that differ according to the affected oral region, many of these lesions are painless, which can cause a delay in the diagnosis and treatment of the disease. Objective: to report a clinical case of a patient with CPB on the oral floor, emphasizing the importance of the dental surgeon in recognizing and diagnosing this disease in early stages. Case report: male patient, 60 years old, phaderoderma, smoker, was referred for painless lesion on the floor of the mouth. On clinical examination, a hard nodular lesion was observed on the floor of the mouth, approximately 3 cm in diameter, with the presence of leukoplastic plaques in its extension and was associated with ulceration in the region of the alveolar ridge. The panoramic radiographic examination showed bone resorption in the ulceration region. Incisional biopsy of the lesion and histopathological analysis were performed, in which it was compatible with CPB. The patient was referred for cancer treatment. Final considerations: thus, it is essential to emphasize the importance of an adequate clinical examination, as well as the early diagnosis of these malignant lesions, favoring a good prognosis for the patient.
