[Cytologic differential diagnosis of various peripheral lung cancers].

The data on 25 cases of histologically verified bronchioloalveolar carcinoma and papillary adenocarcinoma are discussed. Reliable differential diagnostic cytological features of both diseases were established using a statistical, program and fine-needle biopsy findings. Statistical analysis data pointed to the sets of cytological features: "serial pattern--clear cell boundaries" and "serial pattern--presence of macrovacuoles" as a major factor of accuracy of bronchiolo-alveolar carcinoma and papillary adenocarcinoma diagnosis.

[Cytological differential diagnosis of different variants of peripheral lung tumors].

Cytological differential diagnostic features of bronchiolo-alveolar carcinoma and papillary adenocarcinoma are established basing on the material of needle biopsies by means of Statistica program. It is found that the strongest influence on the cytological diagnosis of these two tumors is associated with the following pairs of cytological features: lane--clear-cut cell borders and lane--the presence of macrovacuoles.

[Feasibility of pre-operative cytologic diagnosis of pathologic processes in the breast].

Results are available of clinical and cytological diagnosis for 200 patients with histologically established benign lesions of the mammary gland. The use of cytological method at the presurgery stage decreases the number of unjustified carcinoma suspects up to 5%. True cytological diagnosis is established in 90% of mastopathies, 84.
