Blue nevus in a keratin cyst: case report

Abstract

A 35 years old patient reported with a ten years history of a cystic mass involving the skin and subcutaneous tissue over the shoulder. The cyst proved to be a keratin cyst with a blue nevus in its wall. This is an example of a group of lesions known as nevus with cyst, a term applied to different types of cysts that are closely associated anatomically with a melanocytic nevus.
