Abnormal pigmentation in the skin, while rarely of great medical significance, can have powerful psychological and quality of life ramifications. While conventional therapies are often helpful, they carry risks and expense that are undesirable for some.

Disorders of Pigmentation: Hypopigmentation
2021Acquired disorders of hyperpigmentation (ADOH) are a diverse group of disorders that are characterized by increased pigment in the epidermis and/or dermis. ADOH can occur in all skin types but are more pronounced and often more challenging to treat in Fitzpatrick skin types IV–VI.

Disorders of Pigmentation [PDF]
, 2017 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.

Melanin and Neuromelanin: Linking Skin Pigmentation and Parkinson's Disease
Movement Disorders, 2022Neuromelanin‐containing dopaminergic neurons in the substantia nigra pars compacta (SNpc) are the most vulnerable neurons in Parkinson's disease (PD).

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

Skin pigmentation disorders: aetiology, assessment and aesthetic treatment options
, 2014There are various types of skin pigmentation disorders, from less severe forms such as freckles, solar lentigines and post-inflammatory hyperpigmentation, to more severe conditions such as melasma and chloasma.

Nail pigmentation is defined by the presence of melanin in the nail plate. It most frequently has the appearance of a longitudinal pigmented band, called longitudinal mel-anonychia (LM). LM is an important aspect of ungual pathology because it can be the first sign of nail apparatus melanoma.

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.

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).
