Sweet's syndrome affecting the external auditory canal and tympanic membrane.

ABSTRACT

We report a patient who developed left ear pain, dry cough, and fever. The external auditory canal was tender, swollen, erythematous and full of debris. Later the patient developed widespread tender and red skin nodules and pustules that subsequently coalesced to form plaques. Identical lesions developed also in the external auditory canal and the tympanic membrane of the affected ear. Skin biopsy showed dermal neutrophilia, compatible with the diagnosis of Sweet's syndrome. Rapid improvement was achieved with prednisone after the failure of antibiotics.
