title: Teratoma of the nasal septum in a neonate: an endoscopic approach.
abstract: Initial presentation of a white female newborn delivered after normal pregnancy demonstrated a white mass obstructing the left nare. Primary biopsy revealed a focus of fibrotic nasal mucosa that included squamous and respiratory epithelium. After endoscopic resection of the mass, histopathologic examination resulted in the diagnosis of a teratoma. According to our literature review, this is the first case of a teratoma arising from the nasal septum in a white. Worldwide, 3 additional cases have been reported, but none included endoscopic management. This case illustrates our protocol for an endoscopic approach to an obstructive nasal mass in a neonate and our experience in the management of this rare disease.
