title: [Palmoplantar and disseminated porokeratosis: immunohistochemical study].
abstract: We present a new case of porokeratosis plantaris palmaris et disseminata (PPPD), observe in it a histological picture of cornoid lamella in palms, soles, arms, legs and trunk. In this dermatosis, mediant lectins and involucrin to establish keratinocytes alteration. The immunohistochemical studies have reveals not normal formation in the envelope cornea, and fundamentally D-galactose show a marked diminution in the cell membrane.
