Primary poorly differentiated adenocarcinoma of the middle ear.
Adenocarcinoma of the middle ear is seldom encountered in clinical practice. In the past 20 years, nearly 20 cases of primary adenocarcinoma of the middle ear have been reported, and most cases of these tumors have been described without histologic presentation. To our knowledge, only one case of adenocarcinoma originating in the postoperative middle ear has been reported. We describe a case of primary poorly differentiated adenocarcinoma in the middle ear which was surgically treated for chronic otitis media 50 years ago. Planning diagnostic and therapeutic procedures in connection with middle ear tumors is also discussed.
