Definition of Chromhidrosis

Reviewed on 5/12/2021

Chromhidrosis is a very rare condition that causes the secretion of colored sweat. The sweat may become black, green, blue, yellow, or brown. The color and pattern of colored sweat can vary among affected people. The color may be present only in a few locations on the body or may be present all over the body.

Some cases are caused by the pigment lipofuscin in the sweat glands; this pigment is normally present in the body as a sign of wear and tear within cells. Other cases may be due to ingestion of dyes, heavy metals, food colorings, or certain medications. Less commonly, poisoning or infection may cause the condition. While the condition is benign and not associated with any long-term harmful effects, it may cause anxiety and psychological distress.
