Oral cysticercosis.

Cysticercosis is the result of infection with the larval stage of the tapeworm, Taenia solium. The parasite may settle at any site in the body without causing symptoms, which arise almost exclusively from the involvement of brain or eye, and this may occur several years after infection. Cysticercosis is one of the leading causes of acquired epilepsy in Latin America, parts of Asia, and Africa. More cases are being reported in other countries as a result of immigration from endemic areas. Cysticercosis may cause cystic swellings or nodules in the mouth, and these may be the only evidence of the disease. We present a healthy patient who had multiple intraoral cystic swellings that were diagnosed as cysticercosis in a biopsy specimen. Subsequent investigations showed cysticerci in the brain.
