Amyloidosis is a rare condition characterized by the deposition of abnormal protein filaments into the extracellular tissue. Only 16 cases of true primary idiopathic amyloidosis local- ized in the nose and the paranasal sinuses have previously been reported. We present a case of local- ized amyloidosis involving the sinonasal cavities and the nose in a 53-year-old woman. Our patient was operated on as a typical case of chronic rhinosinusitis with polyps, but after 2 years, the patient came back with severe symptoms of nasal obstruction and pain in the frontal and maxillary regions with proptosis of both eyes. Magnetic resonance imaging revealed sinonasal-intraorbital masses. Primary amyloidosis (AL type) was confirmed by tissue biopsy. A systemic workup for additional amyloid deposits revealed no evidence of other diseases. Extended surgery produced a symptomatic improvement.
