The cysticercus is the larval form of the pork tapeworm. Oral cavity involvement of cysticercosis is rare but frequently reported from developing countries. This report presents 3 cases of oral cysticercosis involving the tongue and buccal mucosa in isolation. All 3 patients were treated with surgical excision and had an uneventful postoperative course. A brief review of the PubMed English-language literature search is presented. Oral cavity involvement with cysticercosis presents a diagnostic dilemma. Management is primarily surgical and carries an excellent prognosis., (Copyright © 2018 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.)

Cysticercosis is a common disease in developing countries, but oral lesions caused by this parasitic infestation are rare. We report here a rare case of oral cysticercosis in a 17 year old male who sought treatment for an asymptomatic nodule of the lower lip that had previously been diagnosed as a mucocele.

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.

Cysticercosis is a potentially fatal parasitic disease that rarely involves the oral region in humans. This study includes 21 lesions seen in 16 Latin American patients. There were 8 men and 8 women, with an age range from 6 to 67 years (mean 33.6 years). Most cases appeared as asymptomatic submucosal nodules that resembled mucous cysts or benign mesenchymal neoplasms. Most were found in the tongue (11 cases), followed by buccal mucosa and the lower lip (4 cases each) and upper lip (2 cases). These were well circumscribed, and ranged in size from 1 to 2.5 cm in diameter. Typical histologic features of viable cysticerci were observed in 15 cases, and the presence of colloid degeneration and granular mineralization were detected in only 1 case. In all cases, simple surgical excision was sufficient to ensure complete removal of the lesions without postoperative complications. It is important to carry out a detailed study in every case, in order to exclude the presence of the parasite in other sites.

Background: Cysticercosis cellulosae rarely involves the oral region in humans., Methods: Six cases of oral cysticercosis were diagnosed, three each in lips and buccal mucosa. Diagnosis was made by characteristic gross and histopathologic appearances., Results: Of 146 cases of cysticercosis, 6 (4.1%) were of the oral cavity. All 6 cases were initially seen with painless swellings. Clinical differential diagnosis ranged from retention cyst, lipoma, fibroma, neurofibroma, and angular stomatitis. Histopathologic examination revealed cysticercus larvae., Conclusions: The oral cavity is a rare site of involvement by cysticercosis, even in an endemic area. Histopathologic findings of the excised cyst are diagnostic of the lesion., (Copyright 2001 John Wiley & Sons, Inc.)

Oral mucosa is a rare site for cysticercosis. This paper describes eight cases of cysticercosis involving the oral cavity: four in the buccal mucosa, two in the lips, one in the tongue and one in the gums. All of the patients presented with a solitary superficial mucosal nodule, with duration varying from one month to three years. Larval fragments of cysticercus cellulosae on an inflammatory background were seen in cytologic smears in all cases. Diagnosis of cysticercosis was clinically unsuspected in all these cases prior to aspiration cytologic diagnosis.

Cysticercosis is a condition in which a human acts as the intermediate host of the pork tapeworm Taenia solium. Although cysticercosis is a common disease in some regions of the world and can occur in any body site, oral lesions are rare. This paper reviews the natural history of the disease and reports on seven cases of oral cysticercosis.

Although cysticercosis is a common disease in developing countries, oral lesions produced by this parasitic infestation are rare. In this report we document a case of oral cysticercosis in a 7-year-old girl who sought treatment for an asymptomatic nodule of the left buccal mucosa that had been clinically diagnosed as a mucocele.

Oral cysticercosis affecting the tongue in association with post kala azar dermal leishmaniasis in an adult man is presented. The features that helped to distinguish oral cysticercosis from other conditions endemic in that area are briefly discussed.

Oral appearances of intestinal parasitic disease are rare. One such appearance is the presence in oral tissues of encysted or encapsulated larvae of organisms from the classes Cestoidea and Nematoda. Cestode larvae form cyst-like lesions that are often clinically diagnosed as mucoceles. In these lesions, the cyst cavity is lined by fibrous tissue with inflammatory cells, and contains fluid and the larval stage of a parasite. The diagnosis of these parasitic cysts is more frequently made in younger persons. The cysts may be treated by simple excision, but care must be taken that the cyst does not rupture, as in some parasites this may result in new cyst formation. Nematode infection in the oral cavity, the most common of which appears to be trichinosis, is rarely reported. Patients with oral or maxillofacial (or both) parasitic disease must undergo a thorough medical investigation to exclude possible life-threatening involvement in other parts of the body.
