A case of carcinoma of the external ear adenoma: Patient male, 49 years old. In 1969, the right external auditory canal tumor was found to be painless and normal hearing. In 1978 it was surgically removed. After the external auditory canal continued to bleed, the tumor recurred and gradually increased, resulting in a blocked ear and decreased hearing. In August 1981, our hospital checked that the right external auditory canal was blocked by papillary neoplasms. The surface was uneven, medium in quality, brittle and easy to touch. Followed by another surgery. Postoperative pathological examination: The surface of the tumor was covered with squamous epithelium. The connective tissue underneath showed a large number of cancerous tissues. The cancer cells were diversified. Most of them were tubular and the normal parotid glands were visible on the edge of the cancerous tissue.
