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× 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.展开更多

Methods Analyze the changes in the contents of serum AchRab and sIL-2R, lymphocyte subtypes in peripheral blood lymphocytes before and after thymectomy in 69 patients.Results In the study group significant changes were found in serum contents of AchRab and sIL-2R before and after operation and there was also remarkable change in the number and constitution of peripheral blood lymphocyte subtypes. Conclusion Thymectomy is an effective therapy for MG.展开更多

METHODS From 1994-2005, 118 patients with thyroid cancer who had previously been treated with a nodule-resection or subtotal Iobectomy in other hospitals underwent a surgical re-operation. RESULTS The incidence of residual cancer at the primary site was 38.1%. The lymph node metastasis rate at the central area was 39.8%. The rate of lymph node metastasis in patients with enlarged lymph nodes in the ipsilateral internal jugular chain was 37.5%, The rate of laryngeal recurrent nerve injury was 15.2% in other hospitals while that of the second operation in our hospital was 1.6%. CONCLUSION Nodule-resection or subtotal Iobectomy alone is not indicated for patients with thyroid cancer because of the high rate of local residual cancer. It is important to be familiar with the anatomy of the laryngeal recurrent nerve for thyroid surgery. Exploration to the central area is necessary for differentiated thyroid cancer.展开更多
