A 64-year-old man with a history of diabetes and gallstones was admitted to our institution with suspected pancreatic malignancy. Computed tomography (CT) revealed multiple pancreatic cysts and massive ascites, and endoscopic ultrasonography (EUS) revealed a 28×27-mm hypoechoic mass in the pancreatic head. An EUS-guided fine-needle aspiration biopsy was performed, and there were no malignant findings. Based on the test results and imaging findings, type 1 autoimmune pancreatitis was suspected. The patient was administered 30 mg of prednisolone daily. After 11 days, CT revealed that the pancreatic cysts and ascites had reduced in size.

A 44-year-old woman presented with severe anemia. We strongly suspected gastrointestinal bleeding; however, esophagogastroduodenoscopy, colonoscopy, and computed tomography showed no bleeding sources. Video capsule endoscopy revealed an actively bleeding submucosal lesion within the jejunum. Double-balloon enteroscopy revealed a 20-mm continuously bleeding submucosal lesion in the distal jejunum. We suspected small intestinal vascular malformation and performed surgical resection. The resected specimen pathologically comprised dilated, thin-walled lymphatic channels and blood vessels involving the small intestinal submucosa. Therefore, the patient was diagnosed with small intestinal lymphatic-venous malformation. Postoperatively, the patient recovered well, and recurrence was not observed.
