Melanotsüütidehaigus

Melanotsüütidehaigus refers to a group of disorders affecting melanocytes, the cells responsible for producing melanin, the pigment that gives color to skin, hair, and eyes. These conditions can manifest in various ways, leading to alterations in pigmentation.

One common category within melanotsüütidehaigus is hypopigmentation disorders, where there is a loss or reduction of melanin. Vitiligo is a prime example, characterized by depigmented patches on the skin. Albinism is another condition, an inherited disorder resulting in a complete or partial absence of pigment in the skin, hair, and eyes.

Conversely, hyperpigmentation disorders involve an overproduction of melanin. Conditions like melasma, often triggered by hormonal changes, cause dark patches on the face. Lentigines, commonly known as sunspots or age spots, are small, pigmented spots that appear on sun-exposed areas.

The causes of melanotsüütidehaigus are diverse and can include genetic factors, autoimmune responses where the body mistakenly attacks melanocytes, environmental triggers like sun exposure, and certain medical conditions or medications. Diagnosis typically involves a visual examination by a dermatologist, sometimes supplemented by skin biopsies or genetic testing. Treatment strategies vary greatly depending on the specific disorder and may involve topical creams, light therapy, or other dermatological interventions aimed at managing symptoms or repigmenting affected areas.
