Background Carpal tunnel release is one of most commonly performed procedures in upper extremity surgery, with low complication rates.
Case Description We report a case of epidermal inclusion cyst that occurred in a 44-year old man after carpal tunnel release. The epidermal inclusion cyst formed beneath the previous operation scar and induced recurrent carpal tunnel syndrome. Symptoms resolved completely after excision of the cyst.
Literature Review Epidermal inclusion cysts are the third most common type of hand tumors. Although repeated minor trauma is the most frequent cause, surgical procedures can induce an epidermal inclusion cyst. One case report of epidermal inclusion cyst after carpal tunnel release was found in literature. Etiology, treatment, and prevention methods are reviewed.
Clinical Relevance We hope this case report alerts physicians to the possibility of development of epidermal inclusion cyst after carpal tunnel release and the importance of basic surgical skills, such as gentle handling of a surgical wound, profuse saline irrigation, and careful wound closure with precise approximation of skin edges.
