title: Bathing trunk nevus with extensive vascular involvement.
abstract: An extensive congenital melanocytic nevus is described which, in its deeper portion, had striking neurofibromatous features. At the dermal subcutaneous junction, there were prominent subendothelial collections of nevus cells in large veins. Similar findings have been described in neurofibromatosis. The apparent relationship of these two disorders both histologically and clinically suggests a histogenetic relationship between nevus and Schwann cells.
