Does Branchiogenic Carcinoma Really Exist.

摘要

The clinical, gross, and microscopical features of 22 cases of cystic squamous cell carcinoma of the neck that originally were considered to be of branchiogenic origin are reviewed. Detailed follow-up investigation demonstrated subsequent distal primary sources of these cervical carcinomas in 19 patients. The primary tumors were located mainly in the oronasopharynx (Waldeyer ring), but primary neoplasms were also found in the lungs, larynx, thyroid, and a major salivary gland. This study supports the impression that branchial cleft carcinoma is extremely rare and most difficult to substantiate. (Author)
