Melasma or melanosis is a chronic disease characterized by primary skin hyperpigmentation. This pathology appears due to excessive accumulation and deposition of melanin in the skin. The disease can be either congenital or acquired.
One of the types of the disease is toxic melasma, which appears as a professional dermatosis in individuals when intoxicated with oil or coal products. That is, sensitivity to sunlight arises after contact with lubricants, especially oil, tar, coal tar, etc.
Areas of hyperpigmentation in the form of brown or dark brown spots are often located on the nose, cheeks, forehead, chin, upper lip; less often, such formations can be seen on the neck. First of all, areas of pigmentation formation are open areas that are exposed to direct sunlight.
