title: Unilateral punctate porokeratosis -- case report.
abstract: This case report involves a 20-year-old man with unilateral punctate porokeratosis. The patient presented an 8-year history of numerous asymptomatic keratotic papules and pits with linear distribution on his left pal-mar surface and fifth finger of the left hand. Histopathological examination of the keratotic plug revealed findings of distinct epidermal depressions containing cornoid lamellae. This report review draws attention to differential diagnoses of punctate porokeratosis.
