Oral cysticercosis: a clinical dilemma.

Cysticercosis is a potentially fatal parasitic disease caused by cysticercus cellulosae, the larval stage of Taenia solium. Oral cysticercosis is a rare entity and represents difficulty in clinical diagnosis. This article reports two cases of oral cysticercosis involving buccal and labial mucosa. Both the cases presented with solitary, nodular swelling that had been clinically diagnosed as a mucocele. Histopathology of excisional biopsy revealed it to be cysticercosis. Single, cystic nodular swelling of oral cavity may be the only evidence of cysticercosis and may present first to dentist. These cases emphasise the role of dentist and thorough histopathological examination in the early diagnosis of disease that can prevent potential systemic complication.
