Primary intralabyrinthine schwannoma.

This paper describes a case of primary intralabyrinthine schwannoma removed by transmastoid labyrinthectomy. This case, together with a review of other cases, suggests that the tendency to preserve hearing by surgical treatment of Meniere's disease and the tendency for these tumors not to be discovered unless a labyrinthectomy is performed may mask their occurrence rate. Furthermore, I would hereby introduce both surgical and pathologic evidence suggesting that there may be a predilection in the site of origin of such solitary tumors.
