title: Hyperkeratotic pitted plaques on the palms and soles.
abstract: Lichen planus (LP) and lichen nitidus (LN) present with varied morphology on the palms and soles. We present four unusual cases of palmoplantar LP and LN manifesting as hyperkeratotic plaques with pits. The diagnosis was confirmed histologically. Subtle features like presence of violaceous border suggests LP and plugs within the pits suggest LN.
