Infected Epidermoid Cyst Including Multiple Nails at the Amputated Thumb Stump: A Case Report

Abstract

Fingertip amputation is a common injury among trauma occurring in the upper extremity. After amputation of the fingertip, there are several treatment options according to the degree of damage. Also, the skin flap is sometimes performed when skin defects are accompanied. Among the complications associated with fingertip injury, cyst formation at the amputation stump is rare but some cases have been reported based on the pathologic findings. There was a case of an infected epidermal inclusion cyst containing multiple nail plates at the amputation stump of the thumb, so we would like to report it with a review of the literature.
