Combined nevus

Abstract

There is no consistent and reproducible definition of combined nevus available in the literature. Some authors only refer to an association of a blue nevus and another melanocytic nevus as combined nevus; however, in our understanding, the most comprehensible and logical approach is to define a combined nevus as the association of two distinctive benign melanocytic proliferations in one biopsy specimen. Any combination of two kinds of melanocytic nevi is possible, but since blue nevi, Clark's nevi, Miescher nevi, Unna nevi, and Spitz nevi are the most common melanocytic skin lesions, they are most likely to collide. © 2007 Springer-Verlag.
