Collagenoma in a child with tuberous sclerosis complex causing carpal tunnel syndrome and thumb overgrowth: Case report

Abstract

We report on a child with tuberous sclerosis complex who had progressive enlargement of a collagenoma of the right hand. The tumor resulted in median nerve compressive neuropathy and overgrowth of the thumb. Debulking of the tumor along with median nerve decompression was performed with relief of neurological symptoms. No recurrence of the symptoms was observed during the 1-year follow-up after surgery. To the best of our knowledge, this is the first report of a deep collagenoma in any anatomical location. © 2013 ASSH. Published by Elsevier, Inc. All rights reserved.
