Background:

• Intraoral blue nevi are rare benign melanocytic neoplasms.
• They present as asymptomatic, bluish macules or papules in the oral cavity.

Purpose of the Study:

• To provide a comprehensive review of intraoral blue nevi.
• To discuss their clinical and histological characteristics.
• To outline differential diagnoses and treatment options.

Main Methods:

• Literature review of existing studies on intraoral blue nevi.
• Analysis of clinical and histological findings from reported cases.

Main Results:

• Intraoral blue nevi typically occur on the palate, buccal mucosa, or lips.
• Histologically, they are characterized by spindle-shaped melanocytes in the dermis.
