Autopsy photographs illustrating macroscopic growth patterns in tumor models. A) In passage 4 of PMP-1 some non-adherent mucinous ascites was observed , but adherent tumor tissue dominated the picture with tumor lesions identified on the surface of the urinary bladder, liver hilum and mesentery of the small intestine. B) Passage 0 of the PMP-2 model exhibited almost exclusively large, "solid" tumors adherent to intraperitoneal surfaces such as liver hilum, retroperitoneum and urinary bladder.
