Primary lymphoma of pancreatic mucosa-associated lymphoid tissue (MALT) is extremely rare. Initial suspicion of primary pancreatic lymphoma is hampered by its low incidence. However, it should always be included in a differential diagnosis of pancreatic mass with unusual features, because an accurate diagnosis can avoid unnecessary surgical intervention. A 70-year-old woman presented with melena associated with a mass on the pancreatic head. Endoscopic ultrasonography-guided core-needle biopsy of the pancreatic mass revealed MALT lymphoma. The patient is currently undergoing radiation therapy. We present a case of primary lymphoma of the pancreatic MALT with a review of the literature.

Choriocarcinoma is an aggressively growing and widely metastasizing tumor that originates from trophoblastic cells. A primary gastric choriocarcinoma (PGC), however, is very rare. A 76-year-old female patient visited the emergency department of Wonkwang University Hospital with abdominal discomfort and melena. Esophagogastroduodenoscopy revealed a huge ulceroinfiltrative mass lesion with blood clots on the boundary between the greater curvature side and the posterior wall side of the stomach lower body. CT showed a 3-cm exophytic mass lesion with heterogeneous enhancement, an ulcer lesion at the posterior wall side of the stomach lower body, and multiple enlarged lymph nodes at the splenic artery and left gastric artery nodal stations. She underwent a radical subtotal gastrectomy with a D2 lymph node dissection. The final diagnosis was PGC coexisting with adenocarcinoma based on the pathology results. This paper reports a rare case of primary gastric choriocarcinoma coexisting with adenocarcinoma and discusses the characteristics of this neoplasm with reference to the literature.

Gastric tuberculosis accounts for approximately 2% of all cases of gastrointestinal tuberculosis. Diagnosis of gastric tuberculosis is challenging because it can present with various clinical, endoscopic, and radiologic features. Tuberculosis manifesting as a gastric subepithelial tumor is exceedingly rare; only several dozen cases have been reported. A 30-year-old male visited emergency room of our hospital with hematemesis and melena. Abdominal CT revealed a 2.5 cm mass in the gastric antrum, and endoscopy revealed a subepithelial mass with a visible vessel at its center on gastric antrum. Primary gastric tuberculosis was diagnosed by surgical wedge resection. We report a rare case of gastric tuberculosis mimicking a subepithelial tumor with acute gastric ulcer bleeding.

SUMMARY OF EVENT: Melena with abdominal pain were developed in a patient who had undergone endoscopic retrograde cholangiopancreatography (ERCP) with common bile duct stones removal and endoscopic retrograde biliary drainage (ERBD) using a plastic biliary stent. He subsequently underwent laparoscopic cholecystectomy. For the diagnosis and treatment of hemobilia caused by a plastic biliary stent, selective angiography for gastroduodenal artery with subsequent embolization for small pseudoaneurysm of pancreaticoduodenal artery was done successfully. TEACHING POINT: A plastic biliary stent induced pseudoaneurysm can be a cause of hemobilia after ERCP with ERBD procedure. Selective angiography with embolization for bleeding pseudoaneurysm can be an effective treatment for this situation.

Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) are a group of malignant tumors with varying degrees of neuroectodermal differentiation. Although it may develop in any organs, ES/PNET originating from small intestine is exceedingly rare. We experienced a 9-year-old girl presenting with abdominal pain, melena, and iron deficiency anemia. Imaging work-up showed multiple masses in the small bowel and omentum with disseminated peritoneal seeding nodules, indicating lymphoma as the most likely diagnosis. Pathological reports from explorative diagnostic laparoscopic biopsy showed tumors comprising small round cells with CD99 expression and EWS-FLI1 translocation leading to the diagnosis of ES/PNET. Tumor burden decreased gradually during five consecutive cycles of systemic chemotherapy. The patient received segmental resection of jejunum, followed by adjuvant chemotherapy. This is the first pediatric case of ES/PNET found in small intestine in Korea.

Leptomeningeal carcinomatosis (LMC) is rare metastatic form of gastric cancer. Most cases are diagnosed in the final stage after multiple distant metastasis. An 84-year-old woman was admitted with melena, headache and vomiting. Esophagogastro-duodenoscopy showed an ulceroinfiltrating lesion at the stomach (Borrmann class III), and biopsy revealed a signet ring cell carcinoma. The abdominal-pelvic CT showed no evidence of metastasis. A sudden decrease of consciousness was noted, but the brain CT showed no active lesion while the brain MRI revealed enhancement of leptomeninges. A lumbar puncture was performed and the cerebrospinal fluid study revealed malignant neoplastic cells. With family consent, no further evaluation and treatment were administered and she died six weeks after the diagnosis of gastric cancer. We report an extremely rare case of a patient who initially presented with neurologic symptoms, and was diagnosed LMC from advanced gastric cancer without any evidence of metastasis in abdomen and pelvis.

Dieulafoy lesions, vascular anomalies typically found along the gastrointestinal tract, have been viewed as rare and obscure causes of sudden intestinal bleeding, especially in pediatric patients. Since their discovery in the late 19th century, the reported incidence has increased. This is due to an increased awareness of, and knowledge about, their presentation and to advanced endoscopic diagnosis and therapy. Our patient was a three-year-old male, without a complex medical history. He presented to the emergency department with acute hematemesis with blood clots and acute anemia requiring blood transfusion. Endoscopy revealed four isolated Dieulafoy lesions along the lesser curvature of the stomach, which were treated with an epinephrine injection. The Dieulafoy lesion, although thought to be rare, should be considered when investigating an acute gastrointestinal bleed. These lesions have been successfully treated endoscopically. Appropriate anticipation and preparation for diagnosis and therapy can lead to optimal outcomes for the pediatric patient.

We report of a patient with metastatic adenocarcinoma of the esophagus and stomach from lung cancer. The patient was a 68-year-old man receiving radiotherapy and chemotherapy for stage IV lung cancer, without metastases to the gastrointestinal (GI) tract at the time of the initial diagnosis. During the treatment period, dysphagia and melena newly developed. Upper GI endoscopy revealed geographic erosion at the distal esophagus and multiple volcano-shaped ulcers on the stomach body. Endoscopic biopsy was performed for each lesion. To determine whether the lesions were primary esophageal and gastric cancer masses or metastases from the lung cancer, histopathological testing including immunohistochemical staining was performed, and metastasis from lung cancer was confirmed. The disease progressed despite chemotherapy, and the patient died 5 months after the diagnosis of lung cancer. This is a case report of metastatic adenocarcinoma in the esophagus and stomach, which are very rare sites of spread for lung cancer.

Primary aortoenteric fistula is a direct communication between the aorta and intestinal lumen and it represents a rare but potentially lethal complication of an abdominal aortic aneurysm. However, it may occur less frequently in a naive non-aneurysmatic aorta. Diagnosis is often difficult and delayed in most cases, unless there is a high level of clinical awareness. Urgent surgery is still the recommended treatment. We describe the case of primary aortoenteric fistula of a saccular aneurysm. A 55-year-old woman was referred to our center with hematemesis, melena, and severe anemia who was dignosed previously with unknown saccular abdominal aneurysm.
