| Abstract: | BACKGROUNDHere we present a rare case of localized amyloidosis involving the nasolacrimal duct and lacrimal sac which was managed by endoscopic surgery.CASE SUMMARYA 50-year-old man whose medical history included bilateral ventricular fold and vocal cord amyloidosis complained of bilateral epiphora. Magnetic resonance imaging revealed a neoplasm within the nasolacrimal sac. Characteristic positivity for Congo red staining and birefringence under a polarized microscope proved the diagnosis of amyloidosis. Dacryocystorhinostomy via an endoscope obtained a favorable result. A one-year follow-up found no recurrence.CONCLUSIONThere are few reports on amyloidosis involving the lacrimal outflow system, and management and outcome are not clear. Endoscopic dacryocystorhinostomy can be a choice to relieve symptoms. Regular follow-up and monitoring of systemic diseases are highly recommended. |
