Abstract:
Porokeratosis is a genodermatosis, resulting from a disorder in keratinization due to an abnormal clone of epidermal precursor, presenting with various clinical manifestations but characterized histologically by the presence of cornoid lamella. Diverse clinical variants of porokeratosis exist, which are unified by this general histological feature, but differ in morphology, distribution, and clinical course. The typical lesions of porokeratosis are described by an atrophic center surrounded by an elevated keratotic rim formed by the cornoid lamella. The lesions can be found almost anywhere on the body. We report an unusual presentation of a rare clinical variant, disseminated superficial porokeratosis.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
