A benign teratoma presenting as an obstruction of the nasal cavity: A case report

Abstract

Introduction: Teratoma refers to a neoplasm that recapitulates all three germ layers. Teratomas may be histologically mature and oncologically benign. Teratomas may also be histologically immature while being oncologically benign, or they may harbor malignant components and have the potential to exhibit an aggressive biological behavior. Teratomas of the head and neck are extremely rare and usually present in the neonatal period. As a general rule, pediatric teratomas of the head and neck tend to be oncologically benign, whereas adult teratomas tend to be histologically and oncologically malignant. Most of these teratomas are found in the cervical region and nasopharynx. Calcification within the mass is often evident. Case presentation: A 27-year-old Caucasian man complaining of a nasal obstruction was admitted to our clinic in January 2006. A transnasal endoscopic examination revealed a mass arising from the nasal septum which was completely removed using an endoscopic approach. Histologically, it was determined to be a benign teratoma. Conclusion: Herein, we present a rare case, along with a review of the related literature, in order to emphasize that a benign teratoma of the nasal septum should not be ignored. © 2012 Cukurova et al.; licensee BioMed Central Ltd.
