We describe a 44-year old man who suffered an isolated external auditory canal granulocytic sarcoma in remission of acute myeloid leukemia. The patient confirmed acute promyelocytic leukemia three years ago and the disease was in remission after treatment. Two months ago he presented pain and hearing loss in the left ear and the symptom developed gradually. At otoscopic examination a tumoral lesion was noted in the external auditory canal and computerized tomography scan showed a mass in the left external acoustic meatus without bone erosion.
