Isolated plantar punctate porokeratosis: case report

Porokeratosis is a rare distinct acquired or congenital skin disease of unknown origin, characterized by abnormal keratinization. A rare form of porokeratosis known as punctate porokeratosis is distinguished by raised lesions on the palms and soles that resemble seeds. Punctate porokeratosis might resemble other dermatoses that affect the palms and soles, such as punctate keratoderma, spiny keratoderma, arsenical keratosis, lichen nitidus, and nevus comedonicus. Here, a case of isolated plantar punctate porokeratosis in the skin of colour is shown along with the dermoscopic characteristics that help identify it from other dermatological differential diagnoses.
