Abstract
Objective: The objective of this report is to demonstrate the importance of stomatology, where the search for etiological factors is local or systemic are necessary for the correct diagnosis and treatment of patients. Methods: The information was obtained by reviewing the medical record, interviewing the patient, photographic record of the diagnostic methods to which the patient was submitted and review of the literature. Results: Actinic cheilitis is a common premalignant cutaneous lesion caused by cumulative ultraviolet radiation on the skin exposed to the sun, especially in light-skinned people. We report the case of a 60-year-old male patient, leucoderma, who sought out the stomatology service complaining of a painful injury in the lower lip region for approximately two months and was diagnosed with actinic cheilitis associated with iron deficiency anemia. Treatment was performed for anemia and cheilitis and cicatrization of the lesions occurred. Conclusion: Finally, the importance of the search for etiological factors, whether local or systemic, for the complete treatment of oral lesions is emphasized.
