An unusual case of lymphoepithelial cyst of palatine tonsil

Abstract

Amongst the various cystic lesions of oral cavity, Lymphoepithelial cyst (LEC) is a rare cystic lesion that presents as an asymptomatic submucosal mass and is usually discovered during routine oral examinations. Most common site of occurence is the floor of the mouth but tonsillar involvement seems to be very rare. Pathogenesis involves the excessive accumulation of desquamated epithelial lining in the tonsillar crypt. This results in a dilated obstructed crypt of the palatine tonsil region which presents as a cystic lesion. Here we are reporting a case of 17 year old female with lymphoepithelial cyst of tonsil.
