Branchiogenic carcinoma (malignant branchioma)

The authors describe the characteristics of branchiogenic carcinoma as that of a pathological entity on the occasion of reporting four cases. The clinical course of the disease and the cytological and histological features are discussed on the basis of our observations and literature data. The authors stress the importance of careful and repeated clinical examinations, which exclude the possibility of a primary tumor of other localization, in establishing the diagnosis of branchiogenic carcinoma.
