Abstract：
Dermatologic literature describes nail abnormalities involving nail bed as linear erythronychia or onychomatricoma. The abnormality reflects cognitive content of the nail bed. A resourceful epidermis capable of manifesting in a variety of clinical appearances depends on initiating stimulus affecting remarkably its nail bed matrix cells. These cells are stem cells (NBMSC) migrating distally to cover remarkably the underlying nail bed dermal ridges that are homologous to finger print dermal ridges. Normally, adult nail bed epidermal cells are uniform and keratinize with the stratum corneum without a granular layer.
