**Chloasma** or skin pigmentation associated with the excess presence of melanin can manifest as symptoms of various diseases. Chloasma mainly occurs in women as a result of pregnancy or menopause, when hormone fluctuations are observed in the body. In addition, with chronic diseases of the gastrointestinal tract and endocrine disorders, for example, stomach ulcers, thyrotoxicosis, and adrenal dysfunction, an increase in the concentration of dye in the body occurs. People's phototypes predispose them to the appearance of age spots on the skin due to exposure to ultraviolet radiation. The first signs of chloasma are the appearance of yellowish or pink spots in the armpits, décolleté, neck, chest and back. The disease most often begins with the appearance of a single spot, however, in rare cases multiple spots develop. Pigmentation appears gradually, it can be symmetrical or atypical, and has a rich brown color. The spots can be located on the mucous membrane of the lips, mouth, eyes, nail plates and scalp.
