Infectious agents play a critical role in MALT lymphoma development. Studies from Italy showed Chlamydia psittaci infection in 87% of ocular adnexal MALT lymphomas and complete or partial regression of the lymphoma after C. psittaci eradication in four of nine cases. However, C. psittaci was not demonstrated in ocular adnexal MALT lymphomas from the USA.(More)
A physical map of the euchromatic X chromosome of Drosophila melanogaster has been constructed by assembling contiguous arrays of cosmids that were selected by screening a library with DNA isolated from microamplified chromosomal divisions. This map, consisting of 893 cosmids, covers approximately 64% of the euchromatic part of the chromosome. In addition,(More)
Owing to the rarity of adrenocortical carcinoma (ACC) no prognostic markers have been established beyond stage and resection status. Accelerated glycolysis is a characteristic feature of cancer cells and in a variety of tumour entities key factors in glucose metabolism like glucose transporter 1 and 3 (GLUT1 and -3), transketolase like-1 enzyme (TKTL1) and(More)
The genetic basis of MALT lymphoma is largely unknown. Characteristic chromosomal translocations are frequently associated with gastric and pulmonary cases, but are rare at other sites. We compared the genetic profiles of 33 ocular adnexal and 25 pulmonary MALT lymphomas by 1 Mb array-comparative genomic hybridization (CGH) and revealed recurrent 6q23(More)
Anaplastic large cell lymphomas are associated with the t(2;5)(p23;q35) chromosome translocation in 40% to 60% of cases, leading to a new chimeric gene NPM-ALK. NPM-ALK positive lymphomas are generally reported to be of either T cell or null phenotype. In this report, we describe a diffuse large B-cell lymphoma associated with the classic t(2;5)(More)
Adrenocortical carcinoma is a rare but highly malignant neoplasm with still limited treatment options. Epidermal growth factor receptor (EGFR) has been shown to be overexpressed in many solid tumors, but its expression in adrenocortical carcinoma has been studied only in a limited number of cases. Therefore, we analyzed the expression of EGFR in 169(More)
Der Prototyp der lymphoepithelialen Speicheldrüsenläsion ist die autoimmune Erkrankung M. Sjögren mit den pathognomonischen lymphoepithelialen Gangläsionen (LEL). Die mögliche Transformation in ein Marginalzonen-/MALT-Lymphom kann in Übergangsphasen eine schwierige diagnostische Herausforderung darstellen; hier besteht bei Vorliegen schmaler „Halos“ die(More)
both HA-1 and HA-2 heterozygosity are frequent in the population. Therefore, HLA-A2 positive leukaemias with HA-1 or HA-2 gene affecting karyotypes might be occasionally unrecognised by HA-1 or HA-2 CTLs. In conclusion, mHag loss due to chromosomal aberrations has relevant implications for the eligibility of patients for mHagspecific immunotherapy.(More)
Recently, the occurrence of cyclin D1-positive B cells with mantle cell lymphoma phenotype in the inner mantle zones of morphologically inconspicuous lymph nodes has been described and termed mantle cell lymphoma ‘in situ’. Prevalence and clinical significance of this lesion and related minimal mantle cell lymphoma infiltrates in reactive lymphoid tissues(More)
OBJECTIVE Nonalcoholic fatty liver (NAFL) is thought to contribute to insulin resistance and its metabolic complications. However, some individuals with NAFL remain insulin sensitive. Mechanisms involved in the susceptibility to develop insulin resistance in humans with NAFL are largely unknown. We investigated circulating markers and mechanisms of a(More)
