Multiple Eccrine Hidrocystomas Treated with Botulinum Toxinand Fine Needle Electrocoagulation / 대한피부과학회지

Multiple eccrine hidrocystomas are benign cysts of eccrine duct and occur mainly in middle aged women with numerous translucent papules on the central face. The treatment of multiple eccrine hidrocystomas is difficult because of their numbers and location. We propose a combined therapeutic method of botulinum toxin and electrosurgery for widely spreading eccrine hidrocystomas. Botulinum toxin inhibits sweating by temporarily blocking the release of acetylcholine from cholinergic neurons that innervate sweat glands. Electrosurgical energy is transmitted along cystic fluid and destructs cystic walls. A 62-year-old woman presented with multiple translucent papules on the face and was diagnosed with multiple eccrine hidrocytomas. Electrocoagulation was performed at a low power setting on the whole face and botulinum toxin was injected intradermally for microcystic lesions on the whole face except upper eyelids. The condition was controlled successfully for 4 months. We think that botulinum toxin and fine needle electrocoaglation are effective treatments for multiple eccrine hidrocytomas.

A Case of Palatal Myoclonus Tinnitus Treated with Botolinum Toxin Injection / 대한이비인후과학회지

Palatal myoclonus, a kind of objective tinntius, is an uncommon disorder which shows rhythmic involuntary movement of the muscles of soft palate. Because of inadequate response of the muscles involved in palatal myoclonus to medical therapy, injection of botulinum toxin has been considered. We report a case of palatal myoclonus which had not responded to medical therapy. Injection of botulinum toxin into the muscle under the electromyographic guidance showed complete recovery of tinnitus and no more rhythmic movements of the muscles. Electromyography findings before and after botulinum toxin injection were also demonstrated.
