Porokeratosis is a heterogeneous group of keratinization disorders that exhibit an autosomal dominant mode of inheritance. The histological hallmark that unifies all variants of PK is cornoid lamella, a column of tightly fitted parakeratotic cells. According to the number, size, and distribution of the lesions the following clinical forms of PK have been described; classic porokeratosis of Mibelli (PM), disseminated superficial porokeratosis (DSP), disseminated superficial actinic porokeratosis (DSAP), punctate porokeratosis (PP), porokeratosis palmaris et plantaris disseminata (PPPD), and linear porokeratosis (LP).
