title: [Cytomorphologic diagnosis of benign and malignant tumors of the blood vessels].
abstract: The aim of this work was to define the cytomorphologic patterns of the major cytologic forms of benign and malignant tumors of the blood vessels in order to define the criteria of the diagnosis of these tumors. Parallel cytologic investigations of puncture biopsy specimens and of histologic sections, obtained from 186 patients (156 ones with benign and 30 with malignant tumors) were carried out. Puncture biopsy specimens, impressions, and scrapings off the surface of section of the removed tumors were examined; the preparations were stained according to Kryukov-Pappenheim. Analysis of the findings of histologic and cytologic studies has shown that the features of the cytologic patterns of vessel tumor varieties, distinguished by the authors, helped correctly diagnose the benign or malignant nature of the process by examining the puncture biopsy specimens in 89.8% of cases and identify the histologic type in 41.5% of cases. The per cent shares of recognized benign and malignant tumors were similar: 89 and 90%, whereas the number of identified tumor types was higher in malignant cases than in benign ones: 51.8 vs. 39.5%. Therefore cytologic examinations of the vessel tumor puncture biopsy specimens should be an obligatory component in the complex diagnosis before surgical intervention.
