Resumo: A 67-year-old male patient, smoker and alcoholic, presented lesion in the anterior region of the mouth's floor, with painful symptoms and limited mouth opening, with a report of six months of evolution. On clinical examination, an exophytic and ulcerated lesion measuring approximately 3 cm was observed, which prevented lingual mobility. An incisional biopsy was performed, followed by a histopathological examination that revealed an epithelial malignant neoplasm characterized by the cells proliferation arranged in nests, islands and cords, in addition to the presence of numerous keratin pearls. Cellular and nuclear pleomorphism was also observed, with large cells showing loss of nucleus/cytoplasm ratio, hyperchromatic atypical nucleus or with evident nucleolus and the presence of atypical mitoses, leading the diagnosis of well-differentiated squamous cell carcinoma. The patient was referred to the oncology center and died 1 month after starting radiotherapy.
