This week's artwork was donated by Lonny, a pediatric cancer patient who received treatment at The Children's Hospital of Philadelphia . Laparoscopic treatment of duodenal carcinoid tumor. Wedge resection of the duodenal bulb under endoscopic control. Goblet cell carcinoid of the appendix endoscopically diagnosed and examined with p53 immunostaining. Immunohistologic analysis of gastrointestinal and pulmonary carcinoid tumors.
Gastric carcinoid expresses the gastrin autocrine pathway.
No statistical differences between these two groups were found in the male to female ratio, serotonin activities and Grimelius argyrophilia. Although no generally acceptable definite criteria and definition for atypical carcinoid varieties have yet established, neoplasias of this category seem to have a wide range of histological, histochemical, immunohist- ochemical, ultrastructural and biochemical features that may mostly be placed in between ordinary carcinoids and ordinary carcinomas. Wedge resection of the duodenal bulb under endoscopic control. The tumor measured 8 mm in size, and showed submucosal involvement but no metastasis to the liver and regional lymph nodes. After laparoscopic exposure and lifting of the duodenal wall around the tumor, wedge resection of the duodenal bulb including the tumor was performed successfully with a laparoscopic endostapler under direct endoscopic control.
