title: Porokeratosis plantaris, palmaris, et disseminata.
abstract: We describe a 73-year-old woman with a long-standing history of annular, hyperkeratotic papules that began on the palms and soles and gradually spread to her trunk, extremities, and face. The clinical presentation and biopsy findings were consistent with PPPD, which is a rare subtype of porokeratosis that begins on the palms and soles and gradually spreads to the trunk and extremities. Owing to the risk of malignant degeneration in porokeratosis, patients should be closely monitored with total body skin examinations. There is no definitive treatment for PPPD. Oral retinoids are sometimes helpful although relapses are common after discontinuation of therapy.
