An extensive intraoral blue nevus in an elder patient.

OBJECTIVE: To report a rare case of intraoral extensive blue nevus in an elder patient. BACKGROUND: Oral blue nevi is a well-recognised skin melanocytic neoplasm that rarely occurs in the oral cavity and may mimic melanoma in the early stages. METHODS: An incisional biopsy was performed, and the diagnosis was blue nevus. CONCLUSION: Both the clinician and pathologist must be aware of such a presentation to diagnose and treat appropriately.
