The incidence of primary adrenal gland tumors observed at the Pathology Department, Cracow, in the period of 16 years was examined. The frequency of adrenal lesion in males and females was studied and compared. The mean age of the patients was calculated. The results were shown in tables and diagrams and compared with data given in the WHO Classification of(More)
Nicotinamide N-methyltransferase (NNMT), which converts nicotinamide (NA) to 1-methylnicotinamide (MNA), is up-regulated in the cirrhotic liver. Because MNA displays PGI(2)-dependent anti-inflammatory effects, the up-regulation of NNMT may play a regulatory role in liver inflammation. In the present work, we analyzed changes in NNMT activity in the liver(More)
BACKGROUND Mitochondrial dysfunction has been shown to play an important role in the development of atherosclerosis and nonalcoholic fatty liver disease (NAFLD). Mitochondrial aldehyde dehydrogenase (ALDH2), an enzyme responsible for the detoxification of reactive aldehydes, is considered to exert protective function in mitochondria. We investigated the(More)
Immunophenotype of isolated (disseminated or circulating) tumour cells (ITC) in the blood, bone marrow and lymph nodes were studied in patients with gastric cancer. Coexpression of metalloproteinases inducer (EMMPRIN), chemokine receptors (CCR6, CXCR4) and adhesion molecules (Ep-CAM, CD44) was determined on cytokeratin positive (CK+) cells in CD45- cell(More)
Pheochromocytomas are rare tumours with uncertain clinical behaviour. Histological separation between benign and malignant pheochromocytomas is usually difficult. The utilization of PASS criteria (Pheochromocytoma of the Adrenal Gland Scaled Score) has not provided a solid basis for separating benign from malignant tumours. The aim of this study was to(More)
Pheochromocytomas, uncommon adrenal tumors, have an uncertain behavior. Recently, PASS criteria were proposed for differentiating between benign and malignant cases. These are not perfect, however. The aim of the study was to investigate angiogenesis and mast cell density in context of the clinical behavior and morphologic characteristics of(More)
Angiogenesis (AG) is necessary for cancer progression. In some cases the intensity of AG may affect the prognosis. The aim of the study was to compare the results of vessel density assessment using the stereological method and immunohistochemical reactions for three endothelial markers: CD31, CD34 and vWf. The material consisted of 40 gastric carcinoma(More)
Association of mucinous adenomas of the appendix and mucinous ovarian tumors is well known. The origin of the ovarian tumor (metastasis from the appendix vs independent primary) is still debated. Serrated adenoma is a rare neoplasm of the distal gastrointestinal tract, and its precancerous role in the colorectum was recently postulated. A 74-year-old(More)
Brown bowel syndrome (BBS) is a very rare condition occurring in association with malabsorption syndromes. It is characterised by deposition of granular, brown pigment (lipofuscin or ceroid) in intestinal smooth muscles. Rarely BBS can be complicated by distention of any segment of the bowel. We present a case of BBS associated with massive dilation of(More)
Lymphoepithelial carcinoma of the salivary glands is a very rare malignancy comprising not more than 0.4% of all salivary gland neoplasms in the non-endemic areas. In contrast it is much more frequent among native Greenlanders, North American Inuit (Eskimo) and Southern Chinese people living in Hong Kong. We report a case of a 74-year-old woman of Polish(More)
