Abstract

The epidermal cyst is found in various regions, such as the face, neck, scalp, thorax and abdomen. It is usually small size less than 5 cm. Yet, there have been few reports of a case of epidermal cyst originating from hands. We have experienced an atypical case of 9¡¿5 cm sized multi-lobular giant epidermal cyst on palm with severe adhesion with the digital artery and nerve. Intraoperative finding showed well capsulated multiple mass encircling the digital artery and nerve of the left index finger, long finger, and ring finger. Another unique character noted is the ductal communication between the tumors. While preserving the involved digital artery and nerve, mass was excised under microscopic field. Pathologic diagnosis was epidermal cyst, presenting white cheese-like creamy substance within the cystic mass. Patient had an intact digital sensory and motor function, no recurrence nor any complications at postoperative 1 year.
