A case of pigmented nevi with large mass in maxillary and mandibular gingiva

Abstract

We report a case of pigmented nevi with large masses in the maxillary and mandibular gingiva. Case : A 43-year-old man presented with a black spot on the left maxillary and mandibular gingiva since childhood, and a mass formation in the same area from his twenties. He was referred to our hospital in September 2005. After self-interruption of his consultation two times, the patient consulted us again in April 2016 due to augmentation of the masses. The lobular and pigmented masses had smooth surfaces, were irregular, and were elastic hard in the left maxillary and mandibular gingiva. No abnormal bone resorption was revealed by panoramic radiography and CT. A biopsy was performed to confirm the definitive diagnosis under local anesthesia, and a histopathological examination showed intradermal type pigmented nevus. The patient does not wish surgical treatment and is still under observation without specific treatment.
