Giant Melanocytic Nevus of Oral Mucosa with Gingival Fibromatosis

Abstract

The purpose of this case report is to present this rare subtype of oral nevus, which has a rare location and size. A 45-year-old female patient was referred to our clinic for periodontal disease. Clinical examination revealed a large pigmented lesion on the buccal mucosa and gingival hyperplasia was also detected. The differential diagnosis was hemangioma and malignant melanoma. No pulsation was noted on palpation. Multiple biopsies were obtained at different times and sites of the lesion. The specimens were compatible with a melanocytic nevus and gingival fibromatosis. A giant melanocytic nevus with gingival fibromatosis of the oral mucosa is a rare condition. Clinicians should be careful in clinical examination in such cases and make differential diagnosis for appropriate biopsy and treatment.
