In our hospital over the last 10 years a diagnosis of nodular regenerative hyperplasia was made for 13 patients. Sixty-nine percent of these patients had portal hypertension, representing 27% of all our patients with portal hypertension and a non-cirrhotic liver. Nodular regenerative hyperplasia was the second most frequent cause of portal hypertension in(More)
Morphological and biochemical studies were performed on a brain biopsy from a patient with typical Lafora disease. Qualitative morphological investigation of the cortex showed that the Lafora bodies were most abundant in layers III and V of the cerebral cortex. They were exclusively located in the neurons and their processes. Quantitative morphological(More)
Carcinoid tumors are rare in the middle ear. To our knowledge, only 17 cases could be found in the literature, the first of which was described in 1980. In addition to enlarging on a previous observation we present three new cases. The neoplasms showed a striking, heterogeneous aspect ranging from solid trabecular to tubuloglandular growth patterns(More)
In normal breast tissue and in noninvasive breast carcinomas, various keratin-14 antibodies were reactive predominantly with the basal/myoepithelial cell layer, although mainly in terminal and larger ducts luminal cells sometimes also were stained. A similar reaction pattern was found with an antibody directed against keratin 17, although this antibody was(More)
Extra abnormal chromosomes (rings and giant rods) containing chromosome 12 sequences are characteristic of well-differentiated liposarcoma (WDLPS). By whole chromosome painting we found in 6 WDLPS that minimally 5 chromosomes had contributed to the formation of the extra abnormal chromosomes. To the constant chromosome 12 contribution, sequences were(More)
A 46 year old white man presented with subcutaneous and intramedullary fat necrosis, destructive polyarthritis, and osteolytic bone lesions, complicating a poorly differentiated adenocarcinoma of the tail of the pancreas with metastases in the liver and omentum. There was a 100-fold increase in serum lipase and trypsin activity. His condition deteriorated(More)
Recently we described a new epidermal serine proteinase inhibitor, skin-derived antileukoproteinase (SKALP), also known as elafin. SKALP/elafin was found to be absent in normal human epidermis, but can be induced in vitro and in vivo under hyperproliferative conditions. Here we studied the expression of SKALP/elafin in several types of epidermal tumors(More)
The clinicopathological, ultrastructural and immunohistochemical characteristics of four primary tumors of the middle ear are reported. These neoplasms showed a striking, heterogeneous aspect ranging from solid-trabecular (Type I) to tubulo-glandular (Type II) growth patterns. Secretory activity of the tumor cells was evaluated by immunohistochemistry and(More)
A patient is described with subacute necrotizing encephalomyelopathy proven by autopsy. A slight increase of blood pyruvate and lactate levels with an increased lactate/pyruvate ratio and frequently increased beta-hydroxybutyrate/acetoacetate ratio suggested a disorder of mitochondrial oxidation. A cytochrome c oxidase deficiency was shown in peripheral(More)
A malignant tumor of the second metatarsal in a thirteen-year-old girl with trouble-some clinical and especially light- and electronmicroscopical aspects is described. The findings are discussed in relation to each of the two possibilities to be considered: highly malignant, extra-cranial so-called adamantinoma (poorly differentiated or basaloid type) or(More)
