We evaluated the clinicopathological features of patients who developed intestinal complications following surgery for gastrointestinal non-Hodgkin's lymphoma (NHL) and determined the risk factors for complications. We retrospectively analyzed 28 patients with gastrointestinal NHL who were treated at our institution between January 2007 and June 2012. Seven patients (25.0%) underwent surgery for bleeding, perforation, or ileus caused by the gastrointestinal NHL, particularly those with involvement of the jejunum or ileum. Half the patients with small intestinal NHL required surgery for complications; patients with this form of NHL were therefore considered to be at a high risk of complications. Those with semicircular ulcerative lesions, a protruding deformity, or systemic NHL involving the small intestine were also considered to be at a particularly high risk of intestinal complications.
A 27-year-old man was admitted to a hospital with a complaint of epigastric discomfort. Upper gastrointestinal endoscopy and endoscopic ultrasonography revealed an elevated lesion on the posterior wall of the upper gastric body, and a diagnosis of ectopic gastric pancreas was made. Follow-up endoscopy performed 5 years later revealed an increase in the size of the mass to approximately 5cm in diameter. The location, shape, and clinical course of the mass aroused a suspicion of malignancy; therefore, partial gastrectomy was performed. Histopathologically, the resected mass was diagnosed as ectopic gastric pancreas with chronic inflammation, fibrosis, and bleeding around the acinar cells.
An 85-year-old man with epigastric pain and anorexia was admitted to our hospital. His serum α-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist II (PIVKA II) levels were markedly elevated. Gastrointestinal endoscopy revealed a large mass near the fundus, and computed tomography revealed multiple liver tumors. Intraperitoneal bleeding followed rupture of a liver tumor and was successfully stopped by transarterial embolization; however, regrowth of multiple tumors followed, resulting in liver failure and death within a short period. Autopsy revealed hepatoid adenocarcinomas originating in the stomach that had metastasized to the liver. Hepatoid adenocarcinomas are hypervascular, rapidly growing tumors that may result in the spontaneous rupture of metastatic liver lesions. Transarterial embolization may be a feasible option for the treatment of these ruptured tumors.
A female in her 50s with a four-year history of myotonic dystrophy was admitted to our hospital with hematochezia. She was diagnosed with synchronous colonic cancer of the transverse and sigmoid colon, for which she underwent partial transverse and sigmoid colectomy, respectively. Postoperative respiratory failure resulted in prolonged stay in the intensive care unit. Her liver and renal function gradually deteriorated, and she eventually died from these sequelae on postoperative day 26. Intraoperative liver biopsy revealed cirrhosis arising from non-alcoholic steatohepatitis (NASH). Although myotonic dystrophy is believed to be a multisystem disease, its association with cirrhosis has not been reported in Japan. We therefore report this rare case of liver cirrhosis arising from NASH in a patient with myotonic dystrophy.
An elderly man in his 70s presented with pain in the right hypochondrium. Computed tomography revealed thickening of the gall bladder wall and liver invasion. In addition, fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) revealed an abnormal accumulation in the gall bladder, leading to a suspicion of gall bladder carcinoma. To confirm the diagnosis, endoscopic ultrasound-guided fine-needle aspiration was performed, which revealed a diagnosis of xanthogranulomatous cholecystitis (XGC). FDG-PET revealed decreased wall thickness and standardized uptake value a month later. Cholecystectomy was performed on the basis of a histological and clinical diagnosis of XGC. Histological examination revealed inflammatory and foamy cells and exuberant granulation of the gall bladder wall, confirming XGC.
A 63-year-old man was admitted to Saitama-Kyodo Hospital for the management of obstructive jaundice. Gastrointestinal endoscopy revealed a tumor of the duodenal papilla, and tumor biopsy suggested adenosquamous cell carcinoma. Computed tomography revealed multiple tumors in both the liver and lung, and these were diagnosed as metastases using bronchoscopy-guided lung biopsy and ultrasound-guided liver biopsy, respectively. The patient was treated with gemcitabine therapy after successful management of the jaundice by percutaneous transhepatic cholangiodrainage. However, he died three months after hospitalization. Autopsy confirmed a tumor of the duodenal papilla that had invaded both the pancreas and bile duct; moreover, multiple liver and lung metastases were observed. The pathological diagnoses were adenosquamous cell carcinoma. Histopathological findings revealed a mixture of adenocarcinoma and squamous cell carcinoma and promotion of multiplication of the adenocarcinoma. Adenosquamous cell carcinoma of the duodenal papilla is rare and preoperative diagnosis is challenging. Our case is unique because biopsy suggested the diagnosis before treatment.
A 42-year-old man was admitted to our hospital with a lower extremity rash, general fatigue, and abdominal discomfort. Laboratory findings revealed elevated serum transaminases as well as positivity for the hepatitis B surface antigen and the immunoglobulin M type anti-hepatitis B core antibody. He was diagnosed with a rash typical of Gianotti-Crosti syndrome due to acute infection with hepatitis B virus, genotype A. After admission, the rash gradually decreased; however, serum transaminases and jaundice increased. Entecavir therapy was initiated on day 11 of admission, and his liver function subsequently improved over two weeks. Gianotti-Crosti syndrome is rarely seen in adult patients. It may be important to pay attention to the typical rash of Gianotti-Crosti syndrome because it may provide an important clue to an otherwise asymptomatic acute hepatitis B infection.
We report a case of double liver cancer in an elderly woman with chronic hepatitis C. The patient was diagnosed with two liver tumors when she was in her 70s, and she underwent hepatectomy for the same. Histopathological examination determined that the two tumors were distinct. One was a well-to-moderately differentiated hepatocellular carcinoma (HCC) and the other was a combined hepatocellular carcinoma and mucinous cholangiocarcinoma (ChC). The HCC component was positive for cytokeratin 19, and it infiltrated into the portal vein and artery and the gall bladder. The ChC component was positive for hepatocyte paraffin 1 (HepPar1) staining and infiltrated into the bile duct. There has been no cancer recurrence at 6 months after surgery. Double cancer of the liver with these histological types is extremely rare and interesting, given the origin and differentiation of liver cancer.
