Autoantibody response against tumor-associated antigens is a well-documented phenomenon with(More)
AIM to investigate the specific features of somatostatin receptor expression in the ileal mucosa of patients with inflammatory bowel disease (IBD). MATERIAL AND METHODS Ileal biopsy specimens from 42 patients aged 22 to 55 years, including 16 patients with Crohn's disease (CD), 14 with indeterminate colitis of IBD unclassified (IBDU), and 12 with the(More)
AIM to analyze the generally accepted histological criteria for diagnosing the activity of inflammatory bowel disease (IBD) in patients with therapy-induced endoscopic remission. SUBJECTS AND METHODS Colon biopsy specimens from 57 patients aged from 19 to 52 years (mean age 31±2.5 years), including 41 patients with ulcerative colitis (UC) and 16 with(More)
The analysis of the data available in the literature has shown that telomerase reverse transcriptase TERT promoter may serve as promising markers of malignancy, aggressive disease course, and poor prognosis for malignant tumors of endocrine organs. Considering the established association of mutations with tumors having a poor prognosis (high-grade and(More)
The paper characterizes sclerosing mucoepidermoid carcinoma with eosinophilia, a rare thyroid tumor, including histological and immunohistochemical features. The authors give their observation of a 26-year-old patient. The immunohistochemical findings (positive p63 and TTF-1 tumor cell nuclear staining) show the dual nature of a tumor arising from the cells(More)
The paper gives the data available in the literature on the clinical and morphological features of thyroid lymphomas and on their diagnostic principles. The authors' observation details the histological and immunohistochemical characteristics of primary thyroid extranodal marginal zone lymphoma. The specific feature of the observation is total thyroid(More)
The paper characterizes adrenocortical oncocytoma, a rare adrenal tumor, accompanied by Cushing's syndrome and estrogen and androgen production and provides histological and immunohistochemical features. The authors describe their observation of a 33-year-old female woman. It is shown that estimation of the malignant potential of adrenocortical oncocytomas(More)
