Lymphoepithelial cyst of the submandibular gland

Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland) and the oral cavity (usually the floor of the mouth). there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC) can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography. It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management.
