Neoplasms of reticular dendritic origin are extremely rare and include the follicular dendritic cell sarcoma (FDCS) and the interdigitating reticulum (or dendritic) cell sarcoma (IDCS). In this article, we review the literature pertaining to the two diseases and describe clinical observations and salient pathologic features, including information provided(More)
BACKGROUND & AIMS The evaluation of the degree of hepatic fibrosis is especially important in patients with chronic liver disease. The aim of this study was to study the diagnostic accuracy of noninvasive means. METHODS Sixty-three clinical, biochemical (prothrombin index, gamma-glutamyl transpeptidase and apolipoprotein A1 levels [PGA score]; and(More)
BACKGROUND/AIMS Evaluation of the degree of hepatic fibrosis is especially important in patients with chronic liver disease. Our aim was to study the diagnostic accuracy of abdominal ultrasonography for cirrhosis or fibrosis. METHODS Twenty-three clinical (n=12) and Doppler ultrasonic (n=11) variables were recorded in 243 patients with chronic (alcoholic(More)
BACKGROUND/AIMS Liver fibrosis is mainly evaluated by qualitative histological examination. Although histological semi-quantitative scores and quantitative determination with image analysis are now possible, these methods have not been fully validated and compared. Therefore, we evaluated these two methods prospectively in 243 patients with chronic liver(More)
A case of fatal Epstein-Barr virus infection in a previously healthy girl who was first found to have severe infectious mononucleosis with spontaneous recovery is reported. Because an abnormal immune response to the virus persisted, the disease relapsed, manifesting in cutaneous and pulmonary lesions associated with hemophagocytic syndrome responsible for(More)
Since the first description by Wolfe et al of C-cell hyperplasia (CCH) in asymptomatic relatives of patients suffering from a medullary thyroid carcinoma (MTC), several investigators have described CCH associated with a chronic lymphocytic thyroiditis (CLT) not within the context of MTC or multiple endocrine neoplasia (MEN). We report the study of C-cell(More)
We report a prospective quantitative image analysis study of C cells in 57 normal autopsy thyroid glands, serially sectioned and wholly embedded in paraffin; all slides were immunohistochemically stained for calcitonin. Computerized quantitative image analysis was performed on 47 cases to measure C cell surface area and parenchymatous surface area after(More)
Renin, prorenin and cathepsin B were localized in human lactotrophs using immunoelectron microscopic techniques. Renin and prorenin were found in numerous cytoplasmic granules. Cathepsin B, a lysosomal enzyme known to be able to activate prorenin into renin, was also present in cytoplasmic granules of lactotrophs. The co-localization of renin and prolactin(More)
Autoantibodies directed against cellular constituents rarely react with antigens localized in the Golgi apparatus and little information is available regarding these particular antibodies. Although thousands of samples have been examined for autoantibodies in our laboratory on a routine basis, only three human sera with anti-Golgi antibodies could be(More)
The proton NMR spin lattice relaxation times of bound water (T1b) were studied on frozen rat liver samples during the precancerous step of cancer induction by diethylnitrosamine. Two components of the T1b were found, which show a different temperature dependence of their relative magnetization. Four different steps were identified during the experimental(More)
