[Cytomorphologic diagnosis of benign and malignant tumors of the blood vessels].

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.

[Cytomorphological characteristics and verification of tumors of the adipose tissue].

Analysis of histo-cytologic findings in 171 cases with various tumors of the fatty tissue has shown that the cytograms of such tumors are sufficiently specific, this permitting a correct identification of the type of involvement from the puncture biopsy specimen in 81% of cases and from impressions in 92.3%, and helping diagnose the histologic variety in 28 and 57% of cases, respectively. Therefore, cytologic examinations of puncture biopsy specimens and impressions of the soft tissue tumors may become an obligatory component of a multiple-modality diagnosis, in both preoperative interventions and in the intraoperative period.

[Cytomorphology of fasciitis and its differential diagnosis].

Cytohistologic correlations were studied in 15 cases of fasciitis (nodular--10 and proliferative--5). Cytologic examination of punctate obtained from tumor-like lesions of the soft tissue is the only morphologic procedure available for pretreatment diagnosis of fasciitis. It assured a reliable diagnosis in 9 out of 15 cases.

[Cytologic diagnosis of fibrous tissue tumors].

A histocytologic examination of 118 cases of tumors of the fibrous tissue (64 benign and 54 malignant) was performed. Cytologic examination provided a means for identification of tumor in 80.5% and histologic pattern in 60% of cases.
