pigmentation

Coloration of any part of the body, especially the skin. Normal pigmentation of skin, hair and eyes is occasioned by the presence of melanin-a brown or black pigment produced by cells called melanocytes. Abnormal pigmentation may occur from local or general loss of melanin. ALBINISM is caused by a general deficiency of melanin. Other causes of abnormal pigmentation include skin disease, pregnancy (see CHLOASMA), ADDISON'S DISEASE, CUSHING'S SYNDROME, JAUNDICE and HAEMOCHROMATOSIS.
