Genetic disorders of pigmentation
Clinics in Dermatology, 2005More than 127 loci are actually known to affect pigmentation in mouse when they are mutated. From embryogenesis to transfer of melanin to the keratinocytes or melanocytes survival, any defect is able to alter the pigmentation process. Many gene mutations are now described, but the function of their product protein and their implication in melanogenesis

Pigmentation Disorders in the Elderly
Drugs & Aging, 2019Aging skin is subject to morphological change due to both intrinsic (skin tone, genetics, endogenous hormones) and extrinsic (chronic sun exposure, medications, exogenous pigments) factors. The broad spectrum of transformation includes both hypo- and hyperpigmentation.

Genetic Disorders of Pigmentation
1994Disorders of pigmentation were among the first genetic disorders recognized in humans. The distinctive phenotypes of oculocutaneous albinism (OCA) and piebaldism were known to the ancient Greeks and Romans, and the typical clinical features, modes of inheritance, and genetic heterogeneity of these disorders are apparent even in classical descriptions ...

Skin color can be categorized according to whether it is hypopigmented (lighter than normal skin) or hyperpigmented (darker than normal skin). Pigmentation can be melanin- related or not melanin-related. We consider here only color changes; pigmented tumors, both benign and malignant, are considered in Chapters 20 and 21.

Human variability is most strikingly defined by variations in skin and hair color. Skin pigmentation is primarily a result of melanocyte functioning. However, surrounding keratinocytes, extracellular matrix proteins and dermal fibroblasts also play a role in cutaneous homeostasis and the phenotypic demonstration of color.

Pigment Disorders and Pigment Manipulations
2012Diseases of the pigment system are common worldwide. They may cause a decrease in quality of life, especially in people of color. Moreover, in some people of color, a normal skin itself can cause problems because these individuals do not accept their natural dark color and strive for a lighter complexion to hopefully increase their quality of life ...

Inflammatory changes in the skin are a common feature of many skin disorders; similar changes also occur after trauma to the skin particularly after burns. In some instances there is increased pigmentation (Figure 33), whilst in others there is decreased pigmentation (Figure 34).
