Abstract

Malignant external otitis, also known as necrotizing external otitis, is an aggrebive infection of the exter-nal auditory canal and skull base. We report two cases of atypical malignant external otitis. Pseudomonas aeruginosa was grown in one case, and aspergillus fumigatus in the other case. Both patients presented with otalgia and were hospitalized longer than 30 days for a course of antibiotics treatment. The case of aspergillus infection with facial paralysis and received surgical intervention. The other case of pseudomonas aeruginosa had a history of nasopharyngeal lymphoma and radiation treatments, and died because of relapsed lymphoma 21 months after treatment v.
