1 Introduction Melanocytic nevi are benign proliferations of cells derived from melanocytic cells of neural crest origin with unknown etiology that may be either acquired or congenital [1, 2]. These lesions predominantly affect cutaneous regions and are rarely encountered in the oral mucosa, with an estimated annual incidence of approximately 4.35 cases per 10 million individuals and a prevalence of up to 0.5% in the oral cavity of the general population [1-3].

1 Case Presentation A 12-year-old girl was referred to a private oral pathology center with an 18-month history of painless palatal swelling. Intraoral examination revealed a well-circumscribed submucosal mass in the right hard palate, measuring 2.0 × 1.8 cm. The lesion matched the surrounding mucosa in color, had a soft to fluctuant consistency, and showed no signs of surface erosion or ulceration (Figure 1a).
