Fox-Fordyce Disease Clinical Presentation

History
- Fox-Fordyce disease frequently appears under conditions of heat, humidity, and friction, often appearing suddenly.
- Many patients present after decades of symptoms.
- Few patients are asymptomatic.
- Most patients relate pruritus that disturbs sleep.
- Changing antiperspirants has not been reported to help.
- Some patients report diminution of sweating after the onset of symptoms.
Physical
- The apocrine glands are the site of Fox-Fordyce disease.
- Lesions are most often found in the axillae, where they tend to be bilateral.
- Lesions may also affect the periareolar, inframammary, and pubic areas.
- The primary lesion is a flesh-colored to reddish, smooth, dome-shaped, discrete, and follicular or perifollicular papule.
- Affected areas usually have many papules. The papules usually appear to affect every follicle in a given area.
- Excoriations and lichenification may be seen as a consequence of scratching.
- Sweating is often absent in the affected area.
Causes
- The definite increased prevalence of Fox-Fordyce disease in women has led to an unproved theory of hormonal influences. Reports of cases of Fox-Fordyce disease in prepubertal girls are evidence against the hormonal theory.[5] The exact pathophysiology is still unknown.
- A number of factors, including (1) emotional and/or hormonal influences and (2) alterations in sweat components, have been implicated in Fox-Fordyce disease.
