[Adenogenous cancer of the esophagus].

Bioptates and resected material from patients treated for cancer of the esophagus at the Kazakh Research Institute of Oncology in 1980-1989 were analysed. Adenogenic tumors made up 6.0% of the 1671 cases of esophageal cancer studied.

[Polycystosis of the esophagus].

A rare observation in a male patient of 72 suffering from pulmonary tuberculosis. Severe chronic oesophagitis complicated with polycystosis was found at the autopsy. Multiple retention cysts up to 0.

[Electron microscopic verification of adenocarcinoma of the cardioesophageal area].

Normal gastric and esophageal cardiac glands as well as proper esophageal glands were studied electron-microscopically. Cardiac gastric and esophageal glands were found to differ by chief cells available in the gastric glands and greater amounts of endocrine cells registered in the esophageal glands. The evidence can provide grounds for electron microscopic verification of cardioesophageal adenocarcinoma permitting the pathologist to rest upon the presence of cells resembling those of proper gastric glands and epigastric fossa.
