Nasal or perinasal masses in children may be classified as congenital or developmental masses, inflammatory lesions, or benign or malignant neoplasms. Because of a possible connection with the central nervous system, nasal masses may be difficult to manage. A premature biopsy, or even a noninvasive palpation, may precipitate intracranial infection, meningitis, or severe bleeding. The indolent nature and benign appearance of these lesions shold not lead to deferral of complete evaluation and appropriate treatment.
