    A 65-year-old man was previously admitted to our university hospital thrice in the last 2 years because of acute kidney failure. This time he was admitted because of frequent diarrhea, anorexia, exacerbation of renal function, and hyponatremia. Rectal wall thickening was detected on computed tomography. Subsequently, a rectal polyp with mucous secretion was found on colonoscopy, which was further diagnosed as a subcutaneous villous adenoma on biopsy. Thus, electrolyte depletion syndrome associated with the rectal polyp was thought to be the cause of his symptoms. Finally, the patient underwent abdominoperineal resection of the rectum. Histopathologically, the rectal lesion was diagnosed as a villous/tubularadenoma without malignancy, and this is such a rare case to be reported.

    A 60-year-old female visited our hospital because of the identification of two duodenal tumors on upper gastrointestinal endoscopy performed for the investigation of anemia. The oral ampullary tumor was proven to be a neuroendocrine tumor (NET) on endoscopic biopsy. However, biopsy was not performed for the anal submucosal tumor (SMT) in the third duodenal portion because the tumor was included in the planned resection area. Multiple dermal soft tumors and café-au-lait spots were noted;her mother and daughter showed the same symptoms. The patient was diagnosed with neurofibromatosis type 1 (NF1). Laparotomy revealed more than 10 nodules at the serosal surface of the duodenum and proximal jejunum. Pancreaticoduodenectomy was performed with an additional 30-cm length of the jejunum that included most of the protruding tumors. Pathologically, the ampullary tumor and the other duodenal/jejunal SMTs were NET G2 and gastrointestinal stromal tumors (GISTs), respectively. Here, we report the rare case of simultaneous occurrence of an ampullary NET and multiple duodenal/jejunal GISTs in a patient with NF1.

    A 74-year-old male was diagnosed with transverse colon carcinoma with idiopathic mesenteric phlebosclerosis (IMP). Extended right hemicolectomy with regional lymph node dissection was performed. It has been reported that IMP develops after taking Chinese herbs containing SANSIS for a long time. In this case, the patient had taken such an herb for more than 3 years. In Japan, total 6 cases have been reported on a tumor with IMP, including this case. Immunohistological examination showed that the IMP findings were particularly strong around the tumor. Thus, this case suggests that there is a link between the tumor and IMP.

    An 82-year-old female underwent contrast computed tomography (CT) that revealed multiple ring-like enhanced masses in the pancreatic tail. Additionally, the inside of the masses showed enhancement on contrast endoscopic ultrasound (EUS). She was diagnosed with a pancreatic neuroendocrine tumor on histopathological examination after EUS-guided fine-needle aspiration, and distal pancreatectomy and splenectomy were performed. In the resected specimen, toward the tumor center, tumor cells with lipid droplets and fibrosis were remarkably observed. These rare histopathological features well reflected the image findings of contrast CT and contrast EUS.

    Cirrhotic cardiomyopathy (CCM) is a chronic cardiac dysfunction in patients with cirrhosis and is characterized by altered diastolic relaxation, blunted contractile response to stress, and electrophysiological abnormalities;however, causes of CCM are unknown. Moreover, reduced cardiac afterload due to cirrhosis-related vasodilatation often masks cardiac insufficiency, whereas rapid hemodynamic overload reveals the presence of cirrhotic cardiomyopathy. Herein, we present the case of previously unrecognized cirrhotic cardiomyopathy that became overt with the development of severe acute cardiac failure. The rapidly worsening hepatic hydrothorax increased cardiac preload and intrathoracic pressure, which impaired cardiac filling. Furthermore, cardiac contractile function might have been worsened by hypoxia due to passive atelectasis and concomitant anemia.
