Branchial cleft cyst carcinoma: Myth or reality?

Skepticism has surrounded the existence of branchial cleft carcinoma since the entity was first described in 1882. However, a landmark work of 1950 established four criteria for the diagnosis of branchial cleft carcinoma, the most important criterion being histologic proof of carcinoma arising from a normal cyst epithelium. Of the 43 cases found in an extensive review of the literature, only 7 cases have satisfied all four of the criteria. To this we add 2 patients who had recurrent infections of a cervical cyst as children and later developed carcinoma within these structures. Additionally, we propose a minor modification to the 1950 criteria and a paradigm for diagnosis and management of these lesions.
