[Eccrine hamartoma of the sweat glands simulating localized unilateral hyperhidrosis].

We report on the case of a 31-year-old woman who presented with localized unilateral hyperhidrosis on her lower right arm. Histological features showed a hamartoma of the eccrine sweat glands. Because she was afraid of being overweight, the patient took an appetite depressant. Under this self-medication complete cessation of the localized hyperhidrosis was observed.
