Desmoplastic small round cell tumor (DSRCT) is an aggressive soft tissue cancer that typically arises in serous lined surfaces of the abdominal or pelvic peritoneum, and spreads to the omentum, lymph nodes and hematogenously disseminates especially to the liver. Extraserous primary location has been reported in exceptional cases.
Features include very common findings: Abdominal pain, Abnormal peritoneum morphology, Lymphadenopathy, and Abdominal distention and others; and common findings: Weight loss, Nausea and vomiting, Enlarged liver (hepatomegaly), and Ileus and others. 18 total HPO annotations.
