Patterns of peritoneal spread of tumor in the abdomen and pelvis

Figure 13 Schematic example of the ubiquitous lymphatic channels and nodes along the mesentery. A mass in the rectosigmoid colon (labeled A) can spread superiorly along the lymphatic highway of the sigmoid mesocolon (arrow). Likewise, a mass located in the cecum can spread along the lymphatic channels of the ileocolic mesentery (labeled B).
