Hondrosarcoma of the chest with intraabdominal distribution (case report).

A rare clinical observation of chondrosarcoma metastasis into the abdominal cavity with a specific metastatic ascitic fluid is presented. Chondrosarcomas that occur as a result of malignant transformation of benign chondroma are quite rare. Even less often in the literature, cases of chondrosarcoma metastases are described, especially in a peritoneum with the presence of metastatic ascites.

Application of fluorescent immunocytochemistry in intraoperative diagnostics of metastases in sentinel lymph nodes in early breast cancer.

The aim of the study was to show the possibilities of fluorescent immunocytochemistry in urgent intraoperative examination of sentinel lymph nodes in patients with early breast cancer. The authors analyzed the data on the state of the lymph nodes in 94 patients with early breast cancer who had been operated on since December 2016 to January 2018 in the Department of reconstructive plastic surgery of the breast and skin of the P.A.

Features of differential cytological diagnosis of primary and metastatic liver carcinoma.

The aim of the work was to assess the possibility of the cytological method in the diagnosis of epithelial liver tumors and to determine the cytomorphological criteria in the differential diagnosis of liver carcinomas. The authors analyzed the data of 106 fine-needle aspiration biopsies and 167 smears-prints during cor-biopsy of masses of the liver in patients who were examined at the polyclinic of the oncological dispensary in Nizhny Novgorod in 2016. - 2017 As a result, full-fledged material for cytological examination in the form of smears-prints from cor-biopsy and fine-needle aspiration biopsies was obtained in 75.

Cellular composition research of serous pleural effusion fluids. Conceptual issues of preanalytics.

The purpose of this work was to show the effectiveness of the cytological method on a small number of observations, excluding all possible errors of the preanalytical stage. The paper presents several simple and easily reproducible algorithms for the cytological study of serous pleural effusions with small cellular content. On the example of 20 observations of the study of the cellular composition of serous exudates, a direct dependence of the research results on the preanalytical stage is shown.

Mutation profiling in eight cases of vagal paragangliomas.

Background: Vagal paragangliomas (VPGLs) belong to a group of rare head and neck neuroendocrine tumors. VPGLs arise from the vagus nerve and are less common than carotid paragangliomas. Both diagnostics and therapy of the tumors raise significant challenges.
