Intradermal botulinum A toxin injection for axillary hyperhydrosis.

Axillary hyperhydrosis in children and teenagers may be severe enough to affect social development. Current treatments range from aluminum chloride compounds to surgical removal of sweat glands and sympathectomy. Intradermal injection of botulinum A toxin has recently been found to be a safe and effective alternative in the adult population. Use in children has so far not been documented. We hereby report a case illustrating the use of botulinum A toxin in a 14-year-old girl with disabling axillary hyperhydrosis.
