[Erros in diagnosis of esophageal cancer]

The authors' personal observations reported illustrate difficulties in establishing the proper diagnosis of esophageal pseudotumors. From the complex of modern diagnostic methods roentgenological and fibroesophagoscopic methods with subsequent cytologic and histological assay proved to be mostly effective. Taking into account the degree of the risk of pseudotumor lesions due to their possible malignant transformation in negative cytologic and pathomorphological findings a diagnostic thoracotomy seems to be largely recommended.
