Abstract:
In the present paper we report on a Taiwanese case of X-linked recessive dyskeratosis congenita (DC), confirmed by detection of a 214 C→T mutation in the DKC1 gene, and provide a detailed description of mottled pigmentary changes of the skin, specifically numerous small, whitish macules dispersed against a background of diffuse, finely reticulated hyperpigmentation. The hypopigmented macules showed no discernible erythema upon rubbing or the local application of heat. The naevus anaemicus-like macules may be a relatively common but under-recognized feature in DC. More studies are required to determine the incidence and histopathology of these macules.

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.
