Cysticercosis of the oral cavity: report of five cases and a review of literature.

This paper reports on five cases of cysticercosis of tongue and buccal mucosa, diagnosed on fine-needle aspiration cytology (FNAC), affecting child patients who presented between January 1994 and October 1997. Four cases presented with gradually increasing nodular swelling of the dorsum of tongue and in the fifth case the swelling was situated on the buccal mucosa of the left side. A clinical diagnosis of cysticercosis was not entertained in any of these patients, who each presented with a solitary lesion; instead, it was considered to be a benign cyst or benign tumour of salivary gland or mesenchymal tissue, before FNAC diagnosis. These lesions of the oral cavity may present first to a dentist and, in endemic areas, cysticercosis should be included in the differential diagnosis of solitary nodular lesions of the oral cavity, particularly in young individuals.
