[Cytological diagnosis of rectal polyps]

Cytograms of polyps of the rectum were studied in 62 patients. Impressions of and smears-scrapes from the surface of polyps (taken during rectoromanoscopy) or bioptic specimens served as material of investigation. Smears were stained after Leischman's method. The cytograms were collated with the findings of the investigations of histological preparations stained with hemato-xylin-eosine. The results obtained showed that cytologically, it seemed possible to establish not only the character of the epithelial component of polyps (benign, atypical, or malignant), but to diagnose the histological structure of a tumour (simple, proliferative and malignant forms of adenomatous polyps of the rectum).
