| 1 | Cystic lymphangioma of the pancreas显示文摘Lymphangioma of the pancreas is an extremely rare benign tumour of lymphatic origin,with fewer than 60 published cases. Histologically,it is polycystic,with the cysts separated by thin septa and lined with endothelial cells. Though congenital,it can affect all age groups,and occurs more frequently in females. Patients usually present with epigastric pain and an associated palpable mass. Complete excision is curative,even though,depending on the tumour location,surgery may be simple or involve extensive pancreatic resection and anastomoses. The authors present a 49-year-old woman in whom a polycystic septated mass,35 mm x 35 mm in size,was discovered by ultrasonography (US) in the body of the pancreas during investigations for epigastric pain and nausea. At surgery,a well circumscribed polycystic tumor was completely excised,with preservation of the pancreatic duct. The postoperative recovery was uneventful. Histology confirmed a microcystic lymphangioma of the pancreas. Immunohistochemistry showed cystic endothelial cells reactivity to factor Ⅷ -RA (++),CD31 (+++) and CD34 (-). Postoperatively,abdominal pain disappeared and the patient remained symptomfree for 12 mo until now. Although extremely rare,lymphangioma of the pancreas should be taken into consideration as a differential diagnosis of a pancreatic cystic lesion,especially in women. | Radoje B Colovic Nikica M Grubor Marjan T Micev Henry Dushan E Atkinson Vitomir I Rankovic Mihajlo M Jagodic | 2008 | World Journal of Gastroenterology2008，14，44： | 6 |
| 2 | Perigastric extraskeletal Ewing's sarcoma: A case report显示文摘Ewing's sarcoma (ES) is a neoplasm of undifferentiated small round cells, which occurs in the bones and deep soft tissues of children and adolescents. We present a rare case of a 44-year-old woman with gastric ES presenting with epigastric pain and weight loss. Ultrasound and computed tomography scans indicated a solid/cystic mass in the pancreatic tail. At laparotomy, the tumor was found attached to the posterior surface of the stomach, completely free from the pancreas, with no lymphadenopathy or local metastases. The polynodal, partly pseudocystic, dark-red soft tumor was excised. Histopathology revealed an anaplastic small-round-cell tumor with strong membranous CD99 immunoexpression. Additionally, there was patchy immunostaining for S-100 protein, vimentin, protein gene product (PGP) 9.5 and neuron-specifi c enolase, and weak focal CD117 cytoplasmic immunoreactivity. The patient had no adjuvant chemotherapy; her postoperative recovery was uneventful, and she remains symptom-free, and without any sign of recurrence at 20 mo. To the best of our knowledge, this is only the third ever case of gastric ES. | Radoje B Colovic Nikica M Grubor Marjan T Micev Slavko V Matic Henry Dushan Edward Atkinson Stojan M Latincic | 2009 | World Journal of Gastroenterology2009，15，2： | 2 |
| 3 | Two synchronous somatostatinomas of the duodenum and pancreatic head in one patient显示文摘Somatostatinomas are extremely rare neuroendocrine tumors of the gastrointestinal tract,f irst described in the pancreas in 1977 and in the duodenum in 1979.They may be functional and cause somatostatinoma or inhibi-tory syndrome,but more frequently are non-functioning pancreatic endocrine tumors that produce somatostatin alone.They are usually single,malignant,large lesions,frequently associated with metastases,and generally with poor prognosis.We present the unique case of a 57-year-old woman with two synchronous non-function-ing somatostatinomas,one solid duodenal lesion and one cystic lesion within the head of the pancreas,that were successfully resected with a pylorus-preserving Whipple's procedure.No secondaries were found in the liver,or in any of the removed regional lymph nodes.The patient had an uneventful recovery,and remains well and symptom-free at 18 mo postoperatively.This is an extremely rare case of a patient with two synchro-nous somatostatinomas of the duodenum and the pancreas.The condition is discussed with reference to the literature. | Radoje B olovi Slavko V Mati Marjan T Micev Nikica M Grubor Henry Dushan Atkinson Stojan M Latini | 2009 | World Journal of Gastroenterology2009，15，46： | 1 |
