Single endolabial cysticercosis

Cysticercosis is infestation of human tissues by Cysticercus cellulosae, the encysted larva of Taenia solium. An endemic disease in tropical countries, especially in Latin America, an increase is expected in its frequency in Europe because of increasing shifts in population. We report the case of a Spanish woman who had lived for some time in Bolivia and Peru who presented at our Department with a tumoral growth on the mucosa of her lower lip. Clinically, this was interpreted as a mucocele (salivary mucoid ‘cyst’); but histological study of the excised piece revealed, surprisingly, that it was a single–element cysticercosis.
