BACKGROUND We recently reported that the pathologic mode of infiltrative growth (infiltrative [INF]-alpha, INF-beta, and INF-gamma) of colorectal liver metastases had characteristic morphologic findings, and furthermore showed that the INF type was a prognostic factor for disease-free survival after hepatic resection. HYPOTHESIS Preoperative computed tomographic (CT) findings of the liver nod...
Fat-poor renal angiomyolipoma (fpAML) and cell carcinoma (RCC) are difficult to differentiate misdiagnosis can lead unnecessary nephrectomy. We experienced a case showing “collapsed shape” which reflected fpAML tissue type. A tumor was incidentally discovered in 42-year-old female during an abdominal ultrasound. RCC suspected according CT MRI imaging results, partial nephrectomy performed. Howe...
Hypophysitis that develops in cancer patients treated with monoclonal antibodies blocking cytotoxic T-lymphocyte-associated protein 4 (CTLA-4; an inhibitory molecule classically expressed on T cells) is now reported at an incidence of approximately 10%. Its pathogenesis is unknown, in part because no pathologic examination of the pituitary gland has been reported to date. We analyzed at autopsy...
BACKGROUND: Metallothionein (MT) protein expression deficiency has been implicated in carcinogenesis while MT over expression in tumors is indicative of tumor resistance to anti-cancer treatment. The purpose of the study was to examine the expression of MT expression in human renal cell carcinoma (RCC) and to correlate MT positivity, the pattern and extent of MT expression with tumor histologic...
INTRODUCTION The staging system for malignant pleural mesothelioma is controversial. To revise this system, the International Association for the Study of Lung Cancer Staging Committee developed an international database. This report analyzes prognostic variables in a surgical population, which are supplementary to previously published CORE variables (stage, histology, sex, age, and type of pro...
Background and Aim: Growth of breast cancer cells is often affected by the female sex steroids. Determination of the cellular concentrations of estrogen (ER) and progesterone (PR) receptors in the tumor is continuously used to predict which patients may benefit from antihormonal therapy. The rate of hormone receptor positivity is related to differentiation and type of tumor tissues, age and men...
Altered chondrocyte differentiation, including development of chondrocyte hypertrophy, mediates osteoarthritis and pathologic articular cartilage matrix calcification. Similar changes in endochondral chondrocyte differentiation are essential for physiologic growth plate mineralization. In both articular and growth plate cartilages, chondrocyte hypertrophy is associated with up-regulated express...
BACKGROUND The ratio of the maximum diameter of consolidation to the maximum tumor diameter (C/T ratio) on thin-section computed tomography (TSCT) and the maximum standardized uptake value (SUVmax) on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) are often used as preoperative independent variables to evaluate the invasiveness of lung adenocarcinoma. We inves...
