Cysticercosis is a condition in which a human being acts as the intermediate host of Taenia solium, a pork tape worm. The oral mucosa is an uncommonly involved site. A rurally living 35 year old vegetarian female presented with a swelling over the right side of her tongue of seven months duration. Histopathology of excisional biopsy revealed it to be cysticercosis. Diagnosis of cysticercosis was clinically unsuspected. The patient was referred to the general medical clinic for further treatment.
