Improvement of Fox-Fordyce disease with botulinum toxin type A.

Abstract

Fox-Fordyce disease is a rare, chronic, pruritic papular eruption affecting apocrine gland-rich areas, predominantly in premenopausal women. There is no standardized treatment for Fox-Fordyce disease and various therapies have yielded mixed results. Botulinum toxin type A injections have shown promise in at least three refractory cases reported in literature. We present an additional case of Fox-Fordyce disease that improved after a single treatment with Botulinum toxin type A.
