[Amyloidosis of the external auditory canal].
Amyloidosis involving the external 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.
