The most common type was the epidermoid cyst. The incidence of epidermoid cyst in the head and neck area were about 1.6 to 6.9%. The epidermoid cyst in the oral cavity was only about 0.01% of all oral cystic lesions. Pathogenesis of the epidermoid cyst was still unknown. It could be congenital or acquired. The most common site of epidermoid cyst in the oral cavity was in the midline, above or under mylohyoid muscle with slowly growing, painless mass.
