Abstract

Teratomas are embryonal neoplasms that show characteristics from all three germ layers(ectoderm, endoderm, and mesoderm). These tumors are frequently present in infancy and childhood. Teratomas are classified into three groups : mature teratoma, immature teratoma, and teratomas with malignant elements. The histopathologic findings of immature teratoma is primitive neuroepithelial cells compounding pseudostratified tubular formations. The pure immature teratoma accounts for fewer than 1% of all germ cell malignancies. The immature teratomas in nasal cavity are very rare tumor. These tumors are often presented as neonatal respiratory distress, nasal obstruction and epistaxis. We report a case of histologically confirmed immature teratoma in nasal cavity in 48 years old man with review of the literature.
