ba c k g r o u nd: skin  metastases occur  in  1-5%  of  solid  tumors  and  are  rarely the presenting sign of internal malignancies. certain features in skin lesions raise suspicion of metastasis from solid tumors. c a s e presentation: in this article a 61-year-old woman is presented with erythematous skin nodules  in  upper  abdomen  and  chest. histopathological evaluation  of  lesions sug...

Background: Breast cancer is a malignant proliferation of epithelial cells that lining the ducts or lobules of the breast. Breast cancer is the second common cancer (after lung cancer) in women. Gallic acid, being a polyphenols, has been reported for its antiproliferative activity against many cancer cell lines. Objective of the present study is effect of gallic acid on proliferation and apopto...

Myoepithelial cells have been implicated in the regulation of the transition from in situ to invasive neoplasia in salivary gland tumors. Considering the importance of the microenvironment of the tumor, the present in vitro study therefore analyzed the morphological and phenotypic changes undergone by benign myoepithelial cells from pleomorphic adenoma (PA) stimulated by tumor-conditioned mediu...

In the present study, we have measured acetylation phenotype in 45 patients who had undergone surgical resection of a primary adenocarcinoma of the breast and in 48 patients or volunteer subjects with no breast disease. Phenotype was determined by measuring the ratio of N-acetylsulfamethazine to N-acetylsulfamethazine plus sulfamethazine in plasma 6 h after a p.o. dose of sulfamethazine. In the...

Pancreatic cancer is an almost universally lethal disease and despite extensive research over the last decades, this has not changed significantly. Nevertheless, much progress has been made in understanding the pathogenesis of pancreatic ductal adenocarcinoma (PDAC) suggesting that different therapeutic strategies based on these new insights are forthcoming. Increasing focus exists on designing...

Pancreatic ductal adenocarcinoma (PDAC), a common digestive system cancer, is highly malignant and has a poor disease outcome. Currently, all available examination and detection methods cannot accurately predict the clinical outcome. Therefore, it is extremely important to identify novel molecular biomarkers for personalized medication and to significantly improve the overall outcome. The "nonc...

Parathyroid carcinoma is a rare malignant neoplasm associated with known cancer syndromes. Hyperparathyroidism, as often observed in parathyroid carcinoma, is associated with an increased risk of developing breast cancer. A 76 year-old male patient treated with surgery and bicalutamide for parathyroid adenocarcinoma came to our observation during follow-up. 18F-FDG PET/CT showed a pathological ...
