Abstract
Self-induced lesions or factitious ulcer of the mouth can be manifestation of unusual or aggressive oral habits or an emotional disorder. Here, we report 2 rare cases of difficult management of factitious ulcer. The first was an 18-year-old male patient who was a former alcohol, tobacco, marijuana, and cocaine user referred to the stomatology service because of lateral tongue lesion because the lesion itched and burned. The second occurred in a 10-year-old male patient who was taken to service because of a lip injury. The patients had the lesions treated but presented recurrence; biopsy specimen revealed a chronic inflammatory process. Systemic and local alterations that justified the ulcerations were investigated but were not found. Low-level laser therapy was performed for the 2 patients. The clinical follow-up, clinical history, and histopathologic aspects for the lesions were of great importance, and diagnosis was chronic wound by self-inflicted thermal injury.
