Neuroendocrine liver metastases: Contributions of endoscopy and surgery to primary tumor search

Figure 3 Operative specimen from a neuroendocrine tumor patient with bulky disease in the mesentery; no primary tumor could be found pre- or intraoperatively. The mesenteric tumor was resected en bloc, along with the adjacent loop of the ileum (arrow); meticulous histopathological work-up of this ileal loop yielded two foci of neuroendocrine carcinoma.
