Dermoid cysts are uncommon clinicopathological lesions of developmental origin. Their etiology is not yet clear and can be associated with entrapment of ectodermal and mesodermal components when the 1st and 2nd branchial arches of each side fuse in the midline. The entrapped tissues then undergo proliferation and cystic transformation. These benign lesions are encountered throughout the body and rarely occur in the head and neck region, 1.6 to 7%. In this case, a 35 year - old- male presented with a painless swelling in the submental region at the right front side of neck. Although various investigations pinpoint to the diagnosis, the final confirmation is obtained after histopathological examination of the excised cyst and the present case was confirmed to be a dermoid cyst.
