Female patient, 57 years old, melanoderma, attended the Faculty of São Leopoldo Mandic reporting severe pain throughout her face with difficulty in eating, speaking and a bad taste in her mouth. In the intraoral examination an area of necrosis was found in the region of tooth 38, three months after extraction and 10 years after radiotherapy.
