Apocrine chromhidrosis is an extremely rare and impressive skin disorder. Primarily after emotional stress patients complain of coloured sweat secretion (black, green, blue or yellow). The deposition of lipofuscin in the apocrine glands may be the cause of this disease, the different colours of sweat being due to various oxidation stages of lipofuscin. We report two patients, one with blue and one with green axillae; the clinical features, histopathology, differential diagnosis, and pathogenesis of apocrine chromhidrosis are discussed.
