Key Points
*Rare skin condition in which sweat become trapped in the hair follicle, mostly affecting women
*Exact cause is unknown, though it is thought that hormones and alterations to the chemical makeup of sweat may play a part in its development
*Consists of small papules, flesh or red colored, usually in the armpits but sometimes in the groin, at times  causing inflammation and itching, which may be intense

Fox-Fordyce Disease is a rare skin condition in which sweat becomes trapped within hair follicles due to the formation of a plug in the follicle. Initially presents as small papules in the affected area, red to flesh colored and accompanied by intense itching due to the rupture of sweat ducts. Affected skin may become darker and thicker due to scratching. Sweating may be greatly reduced or disappear completely from the area. In some cases, no symptoms develop. The condition generally affects follicles in the underarms, although the pubic or nipple region may occasionally be involved.

While Fox-Fordyce Disease most commonly affects women between 13-35, it is rarely seen in men or children. While the exact cause of the formation of follicle plugs is unknown, it is suspected that changes in hormones and/or alteration of the chemical makeup of sweat may play a part in its development. Heat, humidity and stress may also be factors in its appearance.
