Atypical invasive external otitis from Aspergillus.

We report a rare case of invasive external otitis caused by aspergillosis in an elderly nondiabetic patient. Amphotericin B therapy was curative. Atypical features of the presentation delayed diagnosis. Early use of tissue biopsy and culture to guide prompt initiation of therapy is recommended. The clinical spectrum and microbiology of invasive aspergillosis are also reviewed.
