[Caustic burns of the oesophagus in the adult. Histopathological study of 12 cases (author's transl)].

A histopathological study of 12 cases of major caustic burns of the oesophagus serves as a basis for a description of the lesions and to demonstrate the inexorable progression to fibrosis. The lesions are most frequantly diffuse, regardless of the substance responsible. Four morphological stages may be distinguished, superimposed on the clinical picture.
