Patient Q.Q.S., female, melanoderm, 75 years old, attended the dentistry outpatient complaining of asymptomatic volume increase in lingual dorsum region 10 years ago. In anamnesis, the patient reported being a smoker and an alcoholic. At the oral examination, there was a nodular and fibrous lesion, similar in color to the adjacent mucosa on the back of the tongue, measuring approximately 2 cm in diameter. Preoperative examinations were requested, and incisional biopsy was performed. Microscopic examination revealed a tissue fragment coated with stratified keratinized squamous epithelium with no atypia, with intense proliferation of polygonal cells, with rounded, regular nuclei and abundant granular cytoplasm. The anatomopathologic examination was compatible with granular cell tumor. Contrast face tomography examination was requested, but the report is not yet available. The treatment planned by the team of dental surgeons was defined in the follow-up of the lesion every 6 months.
