Primary lymph node gastrinoma in jejunal mesentery.
Primary gastrinomas have been reported in lymph nodes within the gastrinoma triangle. We report a 56-year-old woman with possible primary lymph node gastrinoma in the jejunal mesentery. Six months after excision of the tumor, she is asymptomatic and serum gastrin level is normal.

متن کامل[Factors predictive of retroperitoneal lymph node metastasis in endometrial cancer].
INTRODUCTION It has been suggested that a complete staging may be safely omitted in endometrial carcinoma patients at low risk for lymph node metastasis. The purposes of our study were to explore the prognostic significance of pathologic factors for pelvic and paraaortic nodal spread and to validate the Mayo algorithm in order to identify patients in whom lymphadenectomy may be avoided. MATER...
متن کاملPredictive Factors for Lymph Node Metastasis in Submucosal Gastric Cancer
Purpose: Lymph node metastasis is an important prognostic factor in patients with early gastric cancer. Therefore, we analyzed the predictive factors for lymph node metastasis in submucosal gastric cancer and explored the feasibility of minimally invasive surgery. Methods: The clinicopathological features of 317 patients with submucosal gastric cancer, who underwent radical gastrectomy with lym...
