Abstract
- Eccrine hidrocystomas are benign tumors of the sweat glands that arise from cystic dilatation of the excretory sweat ducts. They may be solitary or multiple. Multiple lesions are observed as small papulonodules having prominent surfaces with a translucent intense bluish dome, localized predominantly to periorbital and malar areas. The diagnosis of multiple eccrine hidrocystomas is clinical, and surgery is the treatment of choice in the case of a single lesion. However, the treatment of multiple eccrine hidrocystomas is challenging and the outcome of conventional therapies varies. Botulinum toxin type-A (BTA) causes chemodenervation at the cholinergic nerve terminal of eccrine glands; accordingly our patient was given intradermal injections of BTA and the result was successful. Herein, we report a case of multiple eccrine hidrocystomas treated successfully with BTA; we believe that BTA can be a novel treatment option for this condition.
