Idiopathic localized crossed (left side of the upper part of the body, right side of the lower part of the body) hyperhidrosis: successful treatment of facial area with botulinum a toxin injection.
BACKGROUND
Localized hyperhidrosis either may be due to an organic cause or may be idiopathic. Most cases of localized hyperhidrosis are reported to be idiopathic and unilateral.
We report a case of idiopathic localized hyperhidrosis with extensive involvement on crossed sides of the body. The hyperhidrotic area on the forehead was treated with a single session of botulinum A toxin injection with a quite successful result, and the area remained free of symptoms during a follow-up period of 5 months.


CONCLUSIONS
All documented cases of idiopathic localized hyperhidrosis are located on one side of the body. To the best of our knowledge, idiopathic localized crossed hyperhidrosis has not previously been reported. The botulinum A toxin injection produced a rapid and successful result on the facial area.
