Hypopigmented pityriasis lichenoides: A new clinicopathological type

Abstract

Pityriasis lichenoides (PL) presents a spectrum of uncommon inflammatory skin diseases that includes acute and chronic variants. The hypopigmented PL is a rare variant that was reported in dark-skinned individuals. It was proved histologically to be a variant of PL chronica (PLC). To our best knowledge, we report the first case of a hypopigmented variant of PL that shows histopathological features of PLC and PL et varioliformis acuta.
