Chromhidrosis or the production of coloured sweat is a rare clinical finding. A 26-year-old female presented with marked pink staining of her uniform and lingerie. Extractions of clothing, skin surface samples, eccrine sebum, urine and a fast food product were spectrophotometrically analysed to identify the pink staining pigment. Three water-soluble colouring agents have been idenfified. An eccrine route of excretion probably produced chromhidrosis. An overview is presented.
