Amyloidoma of the nose in a pediatric patient: a case report.

Localized amyloidosis in the head and neck is a rare and benign disease. Larynx is the most common site of involvement and accounts for 0.2% to 1.5% of benign laryngeal tumors. The oral cavity and pharynx may also be involved in localized amyloidosis of the head and neck. There are only 7 cases of localized nasopharyngeal amyloidosis, and 8 cases of localized nasal amyloidosis reported to date. Out of these 8 cases of nasal amyloidosis, only 1 of them is a pediatric patient. We present the second reported case of localized nasal amyloidosis in a pediatric patient. This case report describes a 10-year-old girl with a 1-year history of right-sided nasal obstruction and mucoid discharge. Examination revealed an irregular erythematous, waxy gray mass arising from the right inferior turbinate. Computed tomography and magnetic resonance imaging showed the mass arising from the inferior turbinates, whereas other investigations excluded systemic amyloidosis. Histology from surgical excision revealed amyloidosis. This case illustrates that although amyloidoma of the nose is rare, it should also be considered as part of the differentials of a nasal mass even in pediatric patients. [Editorial comment: These authors demonstrate that an index of suspicion and confirmation of that suspicion through biopsy and subsequent pathologic evaluations Maybe the only way to avoid missing this potentially important cause of nasal obstruction.]
