The Histopathologic Analysis of 271 Cases of Melanocytic Nevus of the Sole

Abstract

We examined 271 HE stained specimens of melanocytic nevi of the sole. We classified them into 3 patterns according to the location of the tumor cells: junctional, compound and dermal. We classified the junctional type of melanocytic nevi into two patterns according to the existence of the tumor cells, that is nest type and single cell type (without nest). Then we classified each of the nest and single cell types into two patterns based on the distribution of the tumor cells: confined and scattered (pagetoid) type. The characteristics of the melanocytic nevus of the sole are that; most of the lesions are junctional type (247/271=91.1%) and that the scattered type is not rare (58/271=21.4%).
