Abstract

Amyloidosis involving the ear is extremely rare. We present the case of a 76-year-old man who referred unilateral otorrhea and hypoacusis of six months’ duration. The external auditory canal (EAC) was narrowed by a subcutaneous nodule. After its extirpation, unilateral localised amyloidosis of the EAC was diagnosed. In these rare cases, it is crucial to rule out systemic amyloidosis.

Resumen

La afectación de canal auditivo externo (CAE) por la amiloidosis es extremadamente rara. Presentamos el caso de un hombre de 76 años de edad con que consultó por otorrea e hipoacúsia de 6 meses de evolución. El examen mostró un nódulo subcutáneo que ocupaba la luz del CAE y que tras su extirpación se diagnosticó de amiloidosis localizada unilateral. En estos casos es primordial descartar una amiloidosis sistémica.
