Describe chromidrosis.

This is a functional disorder of the sweat-glands characterized by a secretion variously colored, and usually increased in quantity. It is, as a rule, limited to a circumscribed area. The most common color is red. The condition is probably of neurotic origin and tends to recur. (True chromidrosis is extremely rare; most of the cases formerly thought to be such are now known to be examples of pseudochromidrosis.)

Treatment should be invigorating and tonic, with special reference toward the nervous system. The various methods of local electrization should also be resorted to.

Mild antiseptic and astringent lotions or dusting powders should also be advised.

Red chromidrosis or Pseudochromidrosis is a condition in which the coloring of the sweat occurs after its excretion and is due to the presence of chromatogenous bacteria which are found attached to the hairs of the part in agglutinated masses. The axilla is the favorite site. Treatment consists of frequent soap-and-water washings, and the application of boric acid, resorcin, and corrosive sublimate lotions.
