title: Monomorphic adenoma of the nasal septum in a newborn (case report and ultrastructural findings).
abstract: Salivary gland type adenomas of the nasal septum are rare tumors in adults and even rarer in children. There has been no previous report of such a tumor in a neonate. We have described a tumor of the nasal septum whose light and electron microscopic appearances are consistent with an origin from minor salivary gland or nasal mucous glands. Ultrastructural findings presented do not suggest an origin from the embryonic organ of Jacobson (vomeronasal organ). The biological behaviour of this tumor in the neonate is unknown. A study of similar cases will be necessary to elucidate the incidence and natural history of intranasal adenomas in the neonate.
