Targets include leukemias, lymphomas, gliomas, melanoma, and peritoneal carcinomatosis. Other neoplastic causes include leptomeningeal carcinomatosis. Several methods of classification have been used to investigate the extent of carcinomatosis. In older patients DSRCT can resemble lymphoma, peritoneal mesothelioma, and peritoneal carcinomatosis. He was later diagnosed with carcinomatosis, cancer that had spread throughout his body. Previously, the finding of lymphangitis carcinomatosis meant about a six-month life expectancy. The extent of carcinomatosis represents one of the most important prognostic factors. Peritoneal carcinomatosis is the most common peritoneal neoplastic condition. Peritoneal tuberculosis may mimic peritoneal carcinomatosis on CT scan. Although rare, meningeal carcinomatosis can arise from cervical cancer. Peritoneal carcinomatosis explains the liver failure and paraneoplastic syndrome explains everything else. Leptomeningeal carcinomatosis occurs when the cancer cells invade and proliferate in the cerebrospinal fluid.
