Benignes zystisches Teratom als Differentialdiagnose einer medianen Zungenfistel

Zusammenfassung

Teratome der Zunge sind seltene Tumoren der Mundhöhle. Der Fall eines zystischen Teratoms der Zunge mit Fistel zum Zungenrücken wird beschrieben. Teratome mit Anteilen ektodermaler, mesodermaler und endodermaler Strukturen stammen von versprengten primordialen Keimzellen während ihrer Wanderung im Rahmen der Embryogenese ab. Im Falle der Zunge soll das Teratom aus versprengten Zellen des Tuberculum impar während der vierten Woche der Gestation entstehen. Diagnostische Kriterien, differentialdiagnostische Überlegungen und therapeutische Möglichkeiten werden anhand eigener Erfahrungen und der Literatur erörtert.

Abstract

Teratoma of the tongue is a rare tumor of the oral cavity. The case of a benign cystic teratoma of the tongue with a fistula to the dorsum of the tongue is described here. Teratomas are composed of ectoderm, mesoderm and endoderm and arise as a result of displacement of primordial germ cells during their course of migration during embryogenesis. In the tongue, the teratoma may arise from misplaced cells from the tuberculum impar during the fourth week of gestation. Diagnostic criteria, differential diagnosis and possibilities for a treatment are discussed based on our experience and review of the literature.
