    The prevalence of Crohn's disease (CD) in Japan is increasing, and so is the incidence of colorectal and small bowel cancers associated with CD. However, few reports have described the malignant transformation of duodenal lesions; moreover, such a diagnosis is rarely possible preoperatively. We present a case of malignant degeneration in the duodenal mucosa associated with CD. A 54-year-old man had been receiving treatment for CD for more than 20 years. Seven years ago, he was diagnosed with duodenal stenosis related to CD. He was asymptomatic, and biopsy results from the proximal stricture showed inflammatory changes without malignant transformation. The lesion was then monitored during follow-up. In 2013, he underwent an endoscopy, which revealed an ulcerated, nodular mucosa, immediately proximal to a high-grade obstruction of the descending duodenum. A biopsy of the ulcer lesion confirmed a diagnosis of adenocarcinoma. The patient then underwent duodenopancreatectomy. Histopathological results from the resected duodenum confirmed a poorly differentiated adenocarcinoma that had invaded the subserosa. The patient recovered, and no recurrence has been observed. Although the duodenum can be accessed without difficulty during endoscopy, it is challenging to preoperatively diagnose malignant transformation. There are only four reported cases of duodenal cancer stemming from CD-associated stricture, and only one of them received a preoperative diagnosis of malignancy based on endoscopic biopsy results. Progressive duodenal narrowing and ulceration in patients with CD should indicate a need for careful endoscopic evaluation and biopsy in order to exclude malignant degeneration of Crohn's duodenitis. Early diagnosis of cases of CD-associated cancers is necessary. We report the features of a rare and illustrative case of duodenal adenocarcinoma in a patient with CD.

    A 62-year-old man with right upper abdominal swelling was admitted to our hospital. Abdominal computed tomography (CT) revealed a hepatic abscess. He was treated with percutaneous abscess drainage along with antibiotic therapy. After the treatment, the patient was discharged. However, we failed to notice a fish bone, which had been revealed in the CT scan. One year and five months later, the same patient presented with right lower abdominal pain and vomiting. Abdominal CT showed a subcutaneous abdominal abscess of the right lower abdomen, with the same fish bone penetrating out of the ileum. Accordingly, the patient was subjected to surgical abscess drainage, and the fish bone was successfully removed. The findings of this case suggest that the source of infection of the hepatic abscess should be identified, searching not only the nearby organs but also the distally located organs, including the lower gastrointestinal tract. The findings also suggest that the surgical removal of a fish bone should be considered.

    A 17-year-old boy developed prominent mediastinal and subcutaneous emphysema while receiving treatment with 5-aminosalicylic acid (5-ASA) and oral corticosteroids for severe ulcerative colitis. We ruled out infection and initiated oral administration of tacrolimus, after which both the underlying disease and mediastinal and subcutaneous emphysema improved. However, he continued to experience repeated bouts of ulcerative colitis, so we ultimately opted for surgical intervention. Although mediastinal and subcutaneous emphysema is rare, it is one of the known extra-intestinal complications and can be particularly concerning. In this patient, mediastinal and subcutaneous emphysema might have been caused by the vulnerability of pulmonary alveolar walls to steroid medication and the increase of pulmonary alveolar pressure with abdominal pain and breath holding. Here, we report a case of inflammatory bowel disease with mediastinal and subcutaneous emphysema, along with a review of the literature.

    A 58-year-old man was suspected of having a gastric polyp based on an upper gastrointestinal series. Esophagogastroduodenoscopy showed a gastric polyp, approximately 7mm in diameter, located at the greater curvature of the upper gastric body. Helicobacter pylori testing yielded negative results, and there was no atrophy of the gastric mucosa. Biopsy revealed a well differentiated tubular adenocarcinoma (Group 5). Endoscopic submucosal biopsies were performed, and histopathology revealed a well differentiated tubular adenocarcinoma coexisting with a hyperplastic polyp. Complete en bloc resection was performed, in accordance with the current Japanese guidelines.

    A 79-year-old woman was admitted for investigation of epigastric pain and jaundice. Abdominal computed tomography showed a common bile duct stone with a needle-like calcification. Endoscopic sphincterotomy was performed, and the stone was extracted from the common bile duct. After endoscopic sphincterotomy, laparoscopic cholecystectomy was performed. Pathological findings and component analysis of the stone suggested that it was formed from a fish bone. We report a rare case of a common bile duct stone formed from a fish bone.

    A 61-year-old man was admitted to our hospital with extreme weight loss. Abdominal ultrasonography revealed an 8-cm tumor of the pancreatic head. Further investigation revealed orbital, pulmonary, pancreatic, colonic, and bone marrow lesions. A histopathological examination of the pancreatic tumor specimen obtained using endoscopic ultrasound-guided fine-needle aspiration revealed mucosa-associated lymphoid tissue (MALT) lymphoma. Monoclonal rearrangement of immunoglobulin heavy chain was found in the pulmonary, pancreatic, colonic, and bone marrow lesions. We diagnosed multi-organ disseminated MALT lymphoma, with the largest lesion located in the pancreatic head. Chemo-radiation therapy resulted in complete remission.
