Coeliac disease is associated with an increased risk of small bowel lymphoma and adenocarcinoma.' The earliest association between coeliac disease and malignant lymphoma was reported by Fairley and Mackie (1937).2 Histological stains enabled the identification of T-cell lymphoma, now designated as enteropathy-associated T-cell lymphoma (EATL) as the most common neoplasm (96%) associated with co...

Introduction: Primary gastric lymphoma (PGL) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (IHC) and genetic analysis. Case Presentation: A 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise IHC and staging in another center. Inappropriate IHC after surgery showed diffuse large B-cell lymphom...

primary non-hodgkin’s lymphoma of the cranial vault is extremely rare. this case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. biopsy revealed a diagnosis of diffuse large b cell lymphoma (dlbcl)...

BACKGROUND Enterotoxigenic strains of Bacteroides fragilis (ETBF) have been implicated in diarrhoeal illness in livestock and children, but their role in adult human colonic disease is unknown. AIMS To investigate responses by primary adult human colonic epithelial cells to purified B fragilis toxin (BFT). METHODS BFT was purified from culture supernatant of a highly toxigenic strain of ETB...

Colonic epithelial stem cells are believed to be located at the crypt base where they have previously been shown to express musashi-1. The colonic stem cell niche, which includes extracellular matrix and myofibroblasts (together with other cell types), is likely to be important in maintaining the function of the progenitor cells. The aims of our studies were to characterize stem cells in isolat...
