[Morphological variants of glandulo-squamous cell cancer of the esophagus].

Microscopical examination of glandular-squamous cell carcinoma of the esophagus (20 cases) showed the variability of its structure. The following morphological varieties of the glandular tumour component are established: tubular, papillary, cystic, mixed. The degree of the tumour component differentiation can vary and this should be reflected in the histological diagnosis. The ultrastructural features characteristic of squamous and glandular epithelium are identified by electron microscopy.
