Nonalcoholic steatohepatitis (NASH), which is the most severe histologic form of nonalcoholic fatty liver disease (NAFLD), is emerging as the most common clinically important form of liver disease in obese patients. The prevalence of NASH may increase with the rise in the rate of obesity and metabolic syndrome in affluent communities. The aim of this work(More)
BACKGROUND Liver steatosis and iron overload, which are frequently observed in chronic hepatitis C (CHC), may contribute to the progression of liver injury. This study aimed to evaluate the correlation between liver steatosis and iron overload in Polish patients with CHC compared to non-alcoholic fatty liver disease (NAFLD) and HFE-hereditary(More)
The authors examined multiple brain sections from 15 autopsy cases of AIDS for the vascular changes, presence of amyloid plaques and signs of axonal damage. The mean patients age was 33.8 years (range 24-48 years). Neuropathological findings included: HIV-specific changes (5), opportunistic infections (7), lymphoma (1) and two cases with nonspecific(More)
Meningiomas exhibit a tendency to the local regrowth after their surgical resection, and some of those recurrent tumors show histological malignancy progression. The present study was performed on 10 cases of recurrent meningiomas chosen out of total 122 meningiomas diagnosed in our Department of Pathomorphology in the period 1993-1998. The tissue material(More)
A case of meningioangiomatosis, resected from the parietal lobe in a 31-year-old female is presented. Macroscopically, the lesion was composed of five calcified nodules embedded within hardened elastic tissue. Histologically, cortical and subcortical calcified masses were found surrounded by a palisade of spindle and/or oval cells. In adjacent nervous(More)
Chronic pancreatitis and pancreatic adenocarcinoma represent two pathologic phenomena with marked production of connective tissue stroma containing numerous small blood vessels. The aim of this study was to characterise quantitatively the vascular supply of pancreatic adenocarcinoma and fragments of the periductal tissue collected from patients with chronic(More)
Some studies have shown the influence of proteases and vascular density in colorectal primary tumors on spreading and on the course of colorectal cancer. In the present study we have analyzed the relationships between overexpression of cathepsin B protein and angiogenesis intensity in resected colon tumors and their impact on prognosis. It has been(More)
The case presented describes a metastatic carcinoid in the cerebral hemisphere of a 52-year-old woman. The onset of the disease was in the form of stroke, CT-examination showed hemorrhagic focus and edema. A craniotomy was carried out and the lesion was removed. Histological diagnosis stated that the tumor was a carcinoid accompanied by a massive(More)
Histopathological confirmation of clinical suspicion of sarcoidosis is based on the finding of non-caseating granulomas in biopsy material, usually in prescalene lymph nodes or in transbronchial lung biopsies. Lymph node reactive sinus histiocytosis (RSH) seen in relation to various inflammatory and non-inflammatory diseases can mimic the pregranulomatous(More)
