[Cytomorphological features of epithelial tumors of the rectum]

The discharge and scraping from tumors of the rectum in 166 patients (cancer--103, simple polyp--32, proliferating polyp--17, villous polyp--5, malignant polyp--9) were studied at a time by means of various methods of cytoanalysis of suspension preparations (phase contrast, luminescent, supravital microscopy) and of smears (Pappenheim's staining, staining with hematoxilin-eosin, Papanicolaou method). On the grounds of the obtained data the phase optic, cytoluminescent and cytomorphologic patterns of various histological forms of cancer and polyps are set forth.
