One hundred one lymphoproliferative lesions of the gastrointestinal tract (66 malignant lymphomas, 20 pseudolymphomas, and 5 borderline lesions) were reviewed. The pathologic features were compared to the clinical findings, with reference to differential diagnosis and prognosis. Special attention was paid to immunohistochemical features. The gross(More)
Breast carcinomas were examined by the immunoperoxidase technique using antisera specific for lymphocyte subsets, monocytes, NK cells and major histocompatibility antigens (HLA-A, -B, -C; Ia-like). Sixty-four per cent of the patients had a moderate or strong mononuclear cell infiltration, 77% of the patients without mononuclear cell infiltration had(More)
Messenger RNA levels of the c-fos, c-myc, c-Ha-ras and c-Ki-ras genes were studied in 39 tissue samples obtained from 17 patients undergoing surgery for colon carcinoma and other colon diseases. DNA extracted from the same samples was studied by Southern analysis. The tissues were tumors and grossly normal mucosa from each case and in some instances benign(More)
A systematic study of an autofluorescence method is described to improve the early histological diagnosis of myocardial ischaemia. Our results on 732 autopsy cases including 182 cases of sudden death show that the autofluorescence examination of haematoxylin and eosin stained sections of the myocardium is not only reliable in the identification of recent(More)
A case is reported of large fibroid inflammatory polyp of the gastric antrum (Vanĕk tumour) in a 32-year-old woman. The tumour had probably developed over 9 years and had been responsible for several episodes of gastrointestinal bleeding and iron-deficiency anemia. The patient underwent Billroth I procedure with uneventful recovery.

We report 30 cases of non-Hodgkin's gastric lymphomas (according to the Rappaport classification): 1 nodular lymphocytic lymphoma well differentiated, 7 diffuse lymphocytic lymphomas poorly differentiated, 2 diffuse mixed cellularity lymphomas, 20 diffuse histiocytic lymphomas and 4 pseudolymphomas, over a period of 21 years at the CHUV, in Lausanne(More)
Discovery of intestinal ganglioneuromatosis implies the presence of the MEN IIb syndrome or, more rarely, von Recklinghausen's neurofibromatosis. The two conditions are due to dysfunction of the neural crest. This very rare intestinal pathology is illustrated by two observations. The intestinal motility disorders, due to the diffuse proliferation of the(More)
