A 71-year-old man was admitted to our hospital in September 2009 because of severe headache due to meningeal carcinomatosis. In July 2007, subtotal gastrectomy was carried out for gastric cancer. Because intraabdominal cytodiagnosis was positive, he received systemic chemotherapy for 2 years. Recurrent signs were not found on chest or abdominal CT just before hospitalization. He was given NSAIDs and corticosteroid, but his symptom did not improve. Subsequent intrathecal chemotherapy with MTX and Ara-C improved clinical symptoms dramatically. He received care at home for 3 months before he passed away due to pleural and peritoneal recurrence. Recently, since the frequency of meningeal carcinomatosis is increasing, combination treatment of intrathecal chemotherapy and systemic chemotherapy should be considered not only for improvement of clinical manifestations, but also for prognostic improvement.
Extraskeletal neoplasms with osteoclast-like giant cells are very rare. These tumors are most frequently reported in the breast and pancreas, and but rarely in other sites. We report a case of duodenal malignant tumor with osteoclast-like giant cells. The patient was a 76-year-old man who presented with vomiting. Computed tomography, magnetic resonance imaging, and gastrointestinal endoscopy revealed a giant tumor in the ascending part of duodenum. Biopsy specimens showed an undifferentiated malignant tumor with benign multinucleated giant cells. Immunohistochemical staining indicated that the tumor cells were reactive with vimentin, but not with epithelial markers or the other mesenchymal markers, and the multinucleated giant cells were reactive with CD68. Thus, we diagnosed a malignant tumor of the ascending part of duodenum with osteoclast-like giant cells. To the best of our knowledge, this is the first case of duodenal malignant tumor with osteoclast-like giant cells in Japan.
We describe a 54-year old woman with oxaliplatin-induced autoimmune hemolytic anemia and review the clinical features of similar published cases. The present patient had metastatic colon cancer and was admitted to our hospital with a floating sensation and general malaise on day 4 after undergoing the last of 4 cycles of a 7th round of chemotherapy with XELOX. Laboratory data revealed 4.6g/dl hemoglobin and 8.77mg/dl creatinine. Direct and indirect Coombs tests of a blood sample for blood transfusion were both positive. We diagnosed immune hemolysis with acute renal failure based on the clinical course and blood samples showing haptoglobin <10mg/dl. We treated her with hemodialysis, plasmapheresis and immune suppression with prednisolone, which improved the anemia and renal failure.
A 50-year-old man was admitted to our hospital with a chief complaint of melena. An emergency upper gastrointestinal endoscopic study revealed arterial bleeding from a duodenal submucosal tumor, 1.5cm in diameter and about 2cm in an oral direction from the papilla of Vater. Because it was not possible to stop the bleeding, an emergency resection of the tumor was performed. Macroscopically, the ulcerated tumor was approximately 1.5cm in diameter. Histopathologically, the tumor was determined to be located in the accessory papilla of the duodenum. We report here a rare case of bleeding from the accessory duodenal papilla and discuss the literature.
A 66-year-old woman with a history of alcoholic liver cirrhosis and hepatocellular carcinoma was repeatedly hospitalized for the treatment of encephalopathy. Computed tomography demonstrated a portosystemic venous shunt which continued from portal branch P7 to the right renal vein. Since pharmacotherapy for encephalopathy was ineffective, balloon-occluded retrograde transvenous obliteration (B-RTO) was performed to block the portal-renal flow. Hyperammonemia and encephalopathy improved remarkably after the procedure. Intrahepatic portosystemic venous shunt draining into the right renal vein is a rare condition. To the best of our knowledge, management of this type of shunt by B-RTO has not been previously described. We report this case accompanied by a short review of the related literature.
We report a case of primary hepatic actinomycosis showing elevation of serum protein induced by vitamin K absence or antagonist II (PIVKA-II). A 68-year-old man visited an affiliated hospital with a complaint of high fever and body weight loss. Hematological examination revealed severe inflammatory reactions and liver dysfunction. Abdominal CT showed a heterogeneous low density area composed of cystic and solid part. We suspected the cystic part with band-like enhancement to be a hepatic abscess and performed percutaneous transhepatic abscess drainage. Although inflammatory reactions decreased after the drainage, the solid part did not shrink and blood chemistry revealed elevation of PIVKA-II. Since we could not rule out the possibility of hepatoma, right hepatectomy was performed. Histological examination revealed actinomycetes. Although primary hepatic actinomycosis is a rare disease, it must be kept in mind in the differential diagnosis of the liver tumor.
We reported a case of early cystic duct carcinoma concomitant with xanthogranulomatous cholecystitis (XGC). This case was a 72-year-old man in whom thickening of the gallbladder wall was pointed out an abdominal ultrasonography and elevation of the CA19-9 level was detected at a local clinic. Endoscopic ultrasonography and CT demonstrated a mass in the cystic duct. Mapping biopsy using peroral cholangioscopy (POCS) revealed a diagnosis of cystic carcinoma with superficial flat growth, therefore a pylorus-preserving pancreatoduodenectomy was performed. Histopathological diagnosis was well differentiated papillotubular adenocarcinoma with superficial flat spread and the thickening of the gallbladder wall was XGC. A case of early cystic duct carcinoma concomitant with XGC is extremely rare.
A 64-year-old man was found to have a 15-mm tumor in the pancreatic tail by CT angiography 1 year after resection of a left renal pelvic tumor. Clinically, the tumor was preoperatively suspected to be autoimmune pancreatitis. However, surgical resection was performed under a diagnosis of pancreatic ductal cancer, because atypical epithelial cells were detected by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). Pathological examination of the tumor revealed a mass-forming autoimmune pancreatitis. Mass-forming autoimmune pancreatitis is often difficult to preoperatively differentiate from pancreatic carcinoma. Response to steroid treatment and the detection of extrapancreatic lesions may contribute to an accurate diagnosis, thereby avoiding unnecessary surgery.
