Generally, diseases outlined within the ICD-10 codes L80-L81 within Chapter XII: Diseases of the skin and subcutaneous tissue should be included in this category. Disturbances of human pigmentation, either loss or reduction, may be related to loss of melanocytes or the inability of melanocytes to produce melanin or transport melanosomes correctly.
Hypopigmentation is characterized specifically as an area of skin becoming lighter than the baseline skin color, but not completely devoid of pigment. This is not to be confused with depigmentation , which is characterized as the absence of all pigment. [ 1 ]
Postinflammatory hypopigmentation is a highly prevalent pigmentary disease. It can happen to any type of skin. Nonetheless, individuals with darker skin seem to have it more frequently and visibly, perhaps due to the color contrast with their natural skin. The incidence of postinflammatory hypopigmentation is the same for both sexes. [2]
Melanosomes, which are organelles containing melanin, must be transported and increased during hyperpigmentation and tanning, while they shrink during hypopigmentation. [4] Skin pigmentation is frequently caused by sun exposure. To protect itself against UV radiation from the sun, the body makes more melanin. As a result, the skin may become ...
Cross syndrome (also known as "Cross–McKusick–Breen syndrome", "hypopigmentation and microphthalmia", and "oculocerebral-hypopigmentation syndrome") is an extremely rare disorder characterized by white skin, blond hair with yellow-gray metallic sheen, small eyes with cloudy corneas, jerky nystagmus, gingival fibromatosis and severe intellectual disability and physical retardation.
Griscelli syndrome is defined by the characteristic hypopigmentation, with frequent pyogenic infection, enlargement of the liver and spleen, a low blood neutrophil level, low blood platelet level, and immunodeficiency. Very often there is also impaired natural killer cell activity, absent delayed-type hypersensitivity and a poor cell ...
