An Unusual Case of Acute Cholecystitis with Amyloidosis: A Case Report and Literature Review.

We present an extremely rare case of amyloid A (AA) deposition in the gallbladder and review the literature on similar cases. The patient was a 76-year-old man who had been diagnosed with mild bronchiectasis three years previously, who was admitted to the hospital with right upper quadrant pain and fever. Computed tomography revealed swelling and wall thickening of the gallbladder with a small gallstone.

[Bacillus cereus septicemia and necrotizing fasciitis in a patient with liver cirrhosis: a case report].

A 54-year-old woman with hematemesis was referred to our hospital. She had a history of liver cirrhosis and diabetes mellitus. After inserting a Sengstaken-Blakemore tube, we performed endoscopic variceal ligation for ruptured esophageal varices.

Direct cholangioscopy combined with double-balloon enteroscope-assisted endoscopic retrograde cholangiopancreatography.

Double-balloon enteroscope (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) is an effective endoscopic approach for pancreatobiliary disorders in patients with altered gastrointestinal anatomy. Endoscopic interventions via DBE in these postoperative settings remain difficult because of the lack of an elevator and the use of extra-long ERCP accessories. Here, we report the usefulness of direct cholangioscopy with an ultra-slim gastroscope during DBE-assisted ERCP.

[A case of serous cystadenoma of the pancreas associated with obstructive jaundice during long-term follow up].

A 68-year-old man had been followed up since March, 1997 because of a cystic tumor of the pancreas head. The patient developed obstructive jaundice and was admitted to our hospital in June, 2007. The tumor size on CT scan had increased from 3.

[Histological complete response in a case of advanced gastric endocrine carcinoma treated by irinotecan plus cisplatin].

A 65-year-old man was admitted because of epigastralgia and body weight loss. A 50-mm tumor found at the lesser curvature of the gastric antrum was histologically diagnosed as endocrine carcinoma. A computed tomography (CT) scan showed liver metastasis and multiple lymph node metastasis.

Recurrent chromosomal rearrangements at bands 8q24 and 11q13 in gastric cancer as detected by multicolor spectral karyotyping.

Aim: To identify chromosomal translocations specific to gastric cancer (GC), spectral karyotyping (SKY) analysis was performed on established cell lines and cancerous ascitic fluids.

Methods: SKY analysis of 10 established cell lines and seven cancerous ascitic fluid samples identified recurrent chromosomal breakpoints and translocations in GC, several of which involved chromosomal loci of oncogenes or tumor suppressor genes.

Results: A total of 630 chromosomal breaks were identified.

Differentiation of follicular from mucosa-associated lymphoid tissue lymphoma by detection of t(14;18) on single-cell preparations and paraffin-embedded sections.

A 57-year-old woman was referred to the Kyoto Prefectural University of Medicine because of multiple polypoid lesions in the duodenum. On the basis of the histopathologic findings, mucosa-associated lymphoid tissue lymphoma had been diagnosed. The polypoid lesions did not show any improvement in spite of antimicrobial therapy for elimination of Helicobacter pylori.
