Abstract
- Teratomas are true tumours derived from the three germinal layers (ectoderm, mesoderm, endoderm) which differentiate into identifiable tissues and organs. Embryologically, they are thought to result from the displacement of pluripotent cells from normal tissue during embryogenesis. Teratomas commonly occur in the sacrococcygeal region, gonads and mediastinum, but teratoma of the middle ear is exceedingly rare. Treatment for teratomas of the middle ear should be early, complete surgical excision to prevent local destruction and although rare, malignant transformation. We present a case of middle ear teratoma with a review of the literature.
