Abstract:
Darier-White disease (DWD), commonly called Darier disease or keratosis follicularis, is a genodermatosis seen in clinical practice. It exists more commonly in the generalized form but can present as a localized condition. Localized DWD is a rare entity characterized by epidermal changes that are like those seen in the generalized form but that are confined to a small area of skin. This entity is postulated to result from a postzygotic mutation and has the potential to be transmitted to offspring, which may result in the severe generalized form. We report a case of localized DWD diagnosed after biopsy of a recalcitrant linear dermatitis and discuss the salient features of this condition.

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.
