Multifocal and skip involvement is quite a rare developmental pattern for primary gastrointestinal lymphomas. A 25-year-old male patient with diffuse large B-cell lymphoma of the small intestine, with macroscopic features and clinical aspects imitating Crohn's disease and attracting attention with cobblestone-like appearance, is presented herein together with the clinical and pathological features. Multiple ulcerated lesions were also observed infiltrating the serosa with polypoid appearance, 2.5 cm in largest diameter, within the resected jejunoileal specimen, which displayed patchy, healthy-appearing mucosal areas. In microscopic . . .examination, a tumoral infiltration was observed comprised of pleomorphic, atypical lymphoid cells with abundant eosinophilic cytoplasm, marked nucleoli and vesicular nuclei. A B-cell phenotype immunoreaction was observed by vimentin, LCA, CD20, and CD79a in those atypical cells. The diagnosis of the case was diffuse large B-cell lymphoma.The possibility of the presence of this disorder, although rare, is emphasized here for patients applying to the hospital with the signs and symptoms of Crohn's disease Daha fazlası Daha az

Endoscopic cannulation of the biliary tract may be challenging in cases with juxtapapillary, duodenal diverticula. A 70-year-old woman admitted to the hospital with the diagnosis of choledocholithiasis and acute cholangitis. She was placed on antibiotic treatment and parenteral fluid resuscitation. On endoscopic retrograde cholangiopancreatography, the papilla could not be cannulated because of the duodenal diverticulum. Various attempts at biliary cannulation failed. Endoscopic clips were used for evertion and fixation of a partially everted papilla from the diverticulum and for securing it in an orientation that allowed direct can . . .nulation of the biliary tree. Cholangiography demonstrated multiple calculi within the choledochus. She was discharged from the hospital on the 9th day following endoscopic retrograde cholangiopancreatography in good condition. With this report, we aimed to remind physicians that the clip-assisted method is a safe and effective technique for pancreatic and/or biliary cannulation, and should be preferred in patients in whom cannulation is extremely difficult due to large periampullary diverticula Daha fazlası Daha az
