Isolated cysticercosis of tongue: a case report.

Cysticercosis of the tongue is a rare disease caused by infestation with the larval stage of the pork tapeworm (Taenia solium) in which man acts as a secondary host rather than a primary host. Most of these lesions are asymptomatic. The patient usually reports to the physician with the complaint of swelling. The solitary swelling in the tongue of this young 12-year-old girl was not suspected clinically for cysticercosis. Fine needle aspiration cytology, used for pre-operative diagnosis, suggested the possibility of cysticercosis. Detailed medical evaluation was carried out which ruled out neural cysticercosis and other extraneural lesions. The complete removal of the lesion was achieved by simple excision. The histopathological examination confirmed the diagnosis of lingual cysticercosis.
