Amyloidosis of the external auditory canal.
We present a case of bilateral otitis externa that did not respond to local treatment. Cutaneous biopsies revealed bilateral amyloid depositions secondary to multiple myeloma. Persistent, identical bilateral canal lesions may be the only manifestation of treatable systemic disease and should be biopsied, even though their bilaterality argues against malignancy.
