Lymphoepithelial cyst in submandibular region

The lymphoepithelial cyst is a rare, benign, soft tissue, unilocular or multilocular developmental cyst in the head and neck region. It is seen to occur in the salivary glands (parotid>submandibular gland) and oral cavity (floor of mouth/tongue). Among various investigations, FNAC provides immediate diagnosis whereas ultrasonography and CT scan can also be used. The confirmatory diagnosis is always made postoperatively by histopathological examination. Surgery is the mainstay of treatment which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This rare case has been reported to help clinicians bring lymphoepithelial cyst into their differential diagnosis for lesions affecting the submandibular region.
