PATHOLOGIC QUIZ CASE 1
Toribio C. Flores, MD, Richard L. Ruggles, MD, Cleveland
A 48-year-old woman was seen with a ten-month history of hearing loss in her right ear. She was in good health and had had no previous ear trouble, otorrhea, or otalgia.Audiogram and tuning fork tests showed a conductive deafness. On examination in the office, a cyst of the right tympanic membrane was detected.At surgery under local anesthesia, a 1.5-cm, fairly well-demarcated, skincovered polypoid lesion, occupying the inner third of the external auditory canal, was excised. It was pedicled anteroinferiorly to the canal skin, just lateral to the anulus. The tympanic membrane was not involved, and was left intact. Figures 1 and 2 are photomicrographs of the specimen. Postoperatively, the patient's hearing improved, and on testing the air-bone gap was closed.What is your diagnosis?
