Oral melanocytic nevi (OMNs) are rare and benign melanocytic tu-
mors [2, 5, 7, 11]. Long associated with hamartomas, melanocytic nevi
are now considered as neoplasms .
OMNs can be congenital or acquired. They are classified histologically
as junctional, compound, intradermal, combined and blue. This classification is correlated with the location, morphology of the cells and
their distribution [2,7].
