Ovarian seromucinous borderline tumors (SMBTs) are rare. They architecturally resemble serous borderline tumors but are much more frequently associated with endometriosis. The coexistence of other tumors with seromucinous tumors is also extremely rare. Here, we report an unusual combination of bilateral ovarian SMBT and clear cell carcinoma associated with polypoid endometriosis of the colon, i...
Abstract Chimeric antigen receptor (CAR) T-cells are engineered with synthetic receptors that directs their specificity and function toward an of choice. This application has been highly successful in treating a variety blood-borne cancers such as B-cell lymphomas. CAR against solid tumors have less efficacious, potentially due to the resistance tumor cells T cell-mediated cytotoxicity. Current...
Renal transplantation increases the probability of malignant tumors by about 2-4-fold overall with a much higher rate for renal epithelial malignancy. Renal tumors in renal transplant recipients are commonly conventional clear cell or papillary renal cell carcinoma. Clear cell papillary renal cell carcinoma is a recently described unique renal epithelial neoplasm with scant eosinophilic or mode...
the paranasal sinuses are known to be a rare location for metastasis. renal cell carcinoma (rcc) is the most frequent primary tumor to metastasize to the sinonasal region, followed by lung and breast cancer. in particular, clear cell type rcc, which represents approximately 85% of rccs, is characterized by early metastasis, and it sometimes spreads to unusual sites (1, 2). metastatic tumors in ...
Levels of mRNA expressed by the multidrug resistance gene MDR1 were examined in 23 renal cell carcinoma samples and adjacent normal kidney cortex using reverse-transcription PCR. Comparison of MDR1 levels between histological types revealed that there was on average significantly more MDR1 in clear cell tumors than in oncocytomas (0. 89 +/- 0.10 versus 0.28 +/- 0.20, ratio of MDR1 in tumor cell...
خلاصه: سابقه: کارسینوم ادنتوژنیک با سلول روشن( CCOC ) یک تومورادنتوژنیک نادر و مهاجم است که بیشتر در فک پایین ودهه سنی5 تا 7 دیده می شود. این ضایعه بیشتردر زنان گزارش شده و توانایی عود مکرر، متاستاز منطقه ای و دوردست را دارد. تشخیص این ضایعه امری چالش برانگیز بوده و با توجه به تعداد کم گزارش شده از این ضایعه در دنیا، شناسایی ابعاد بالینی، رادیولوژیک، میکروسکوپی و پیش آگهی این ضایعه حائز اهمیت...
background and aims. mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. the distribution and significance of mast cells in many tumors have been demonstrated. however, few studies have evaluated mast cell infiltration in salivary gland tumors. in this study, mast cell counts were evaluated in benign and malignant salivary gland tumors. mat...
