Abstract
Porokeratosis plantaris palmaris et disseminata (PPPD) is a quite rare variant of porokeratosis. We report a 56-year-old male patient. He first noted brownish, asymptomatic, annular macules scattered on the trunk and extremities at about age 31 and these skin lesions, continued to increase in number. Ten years prior to presentation, similar lesions appeared on the palms. About one to two years ago, the patient noted painful wart-like, keratotic punctuate papules 2-3 mm in diameter on the soles, which disturbed walking. Histological examination showed the characteristic feature of the cornoid lamella. The family tree of this patient showed an autosomal dominant mode of transmission. We review sixteen typical cases of PPPD previously reported in the English literature.
