Reed nevus.

Abstract

Reed nevus (2) is considered by some Authors (1) together with Spitz nevus as part of the same spectrum. Reed nevus occurs more frequently in the adolescent and young adult, mainly in females. It affects mainly the lower limb. Reed nevus is clinically characterized by an intensely pigmented papule, which is flat, usually less than 6 mm in size.
It grows rapidly in the first six-ten months and then persists stable. However, its natural history cannot easily be observed because in most cases the nevus is removed before it stabilizes.
On dermoscopy, characteristic is the starburst pattern, with intensely pigmented, homogeneous center and peripheral pseudopods, although other dermoscopic patterns can be observed in Reed nevus.
