Bronhogenny cancer

Bronhogenny cancer is a malignant tumor growing from the remnants of the Gill arches. Is rare. The tumor has a dense consistence, located on the lateral surface of the neck at the bifurcation of the common carotid artery, quickly spaevaet surrounding tissues.
More often bronhogenny cancer occurs in older men. The diagnosis can be made only with the exception of primary malignant tumors in the upper respiratory tract, oral cavity. Bronhogenny cancer in a number of cases it develops in bronhogenny Kista. Treatment is combined preoperative radiation therapy and surgery.

Bronhogenny cancer (from the Greek. branchia - gills, Gill slits and genos - origin) is a malignant tumor of the neck, which is the source of the Gill epithelium pockets and cracks, not otherwise reverse development; can develop secondarily by Gill epithelium malignization fistula or cysts (see Bronhogennaya cyst). Observed mainly in men after the age of 40.
Bronhogenny cancer - dense, sedentary tumor, located at the corner of the lower jaw under the sternoclavicular-liners muscle, near the internal jugular vein. The tumor reaches a large size, quickly merged with the surrounding tissues. Histological structure B. R. depends on its origin. B. R. ectodermal origin built of multilayer epithelium, sometimes orogovevshie. Bronhogenny cancer Endermologie origin has build papillary cystadenoma or squamous non-squamous cancer, and the basis of the tumor consists of lymphadenoid tissue, generally found in Gill formations, which facilitates the diagnosis. B. R. should be differentiated from cancer of the larynx (see) and esophagus (see), tumors carotid gland (see Glamurnye tumors and thyroid cancer, and metastatic tumors and TB of the lymph nodes. Operative treatment, x - ray and radiation therapy. The prognosis is poor; the proximity B. p. to neurovascular bundle neck creates difficulties for the operation; B. R. often recurs, metastases rare.
