Palmar purpuric lichen nitidus—clinicopathological and dermoscopic findings

Abstract

Lichen nitidus (LN) is an uncommon dermatosis of unknown etiology. LN confined to the palms is an unusual presentation and only a few cases have been reported. The clinical features may mimic pompholyx, pitted keratosis, and porokeratotic eccrine ostial and dermal duct nevus. We herein report a rare case of palmar purpuric LN with characteristic dermoscopic findings.
