Cysticercosis is a rare disease caused by the ingestion of the parasite Cysticercus cellulosae, a larval stage of Taenia solium. The definitive host is human who harbors the adult worm and may accidentally or incidentally become the host. The larval form of cyst is commonly seen in the brain, meninges and eyes. Cases in the maxillofacial region including oral cavity and cheek muscles are rarely reported. Cysticercosis is not commonly considered in the diagnosis of swellings of the head and neck and a diagnostic and therapeutic dilemma for clinicians. Hence, they are of utmost interest to the practitioner and have to be studied. We present an unusual case of cysticercosis presenting as a solitary cystic nodule in the upper left vestibule of the oral cavity in an 18 year male and the diagnosis was made on histopathological examination.
