BACKGROUND: Epidermoid cysts are the most common cysts of the skin. They are generally small and slow-growing and rarely reach more than 5 cm in diameter. OBJECTIVE: We present a patient with a giant multilocular epidermoid cyst. METHODS: A 75-year-old man presented with a giant, soft, painless, tumorlike mass on the left buttock that had gradually enlarged over a 12-year period. Excision of the mass from the surrounding tissue was extremely easy because of a well-defined capsule. RESULTS: The 28 x 14 x 12 cm mass was totally excised. A histopathologic examination revealed that it was an epidermoid cyst. CONCLUSION: This rare case of giant epidermoid cyst was treated successfully by local excision followed by primary closure. Dissection of the mass from the surrounding tissue was extremely easy because of a well-defined capsule.
