Essential focal hyperhidrosis is characterized by excessive sweating of certain body areas, particularly axillae, palms, and soles.1,2 So far, no attempt has been made to define axillary hyperhidrosis by quantification of the sweat production over time in a given area. We therefore used gravimetric assessment to compare the sweat production of healthy control subjects with that of patients with disabling axillary sweating.
