Sclerosing nevus with pseudomelanomatous features

Abstract

From our data we concluded that, despite their worrisome clinical and histological aspect, the lesions described in this case series were most probably benign melanocytic nevi, involved by a fibrotic process combined with pseudomelanomatous proliferation. The lack of cytological atypia, mitoses and expansive nodules allowed us to differentiate these lesions from regressing melanomas.
