Definition / general
- In U.S., only 2% of hepatic malignancies in noncirrhotic liver are hepatic primaries (i.e. 98% are metastases) vs. 77% are hepatic primaries in cirrhotic liver
- Direct extension is common from tumors of extrahepatic bile ducts, gallbladder, pancreas and stomach
- Metastases in adults often from breast, colon, lung, pancreas; in children from neuroblastoma, rhabdomyosarcoma, Wilms tumor
- Unknown primary is often determined to be from lung, pancreas, stomach
- Metastatic nodules tend to outgrow their blood supply and produce central necrosis and umbilication
- Symptoms often of abdominal pain, ascites and jaundice; portal hypertension less common
- Survival usually less than 1 year, longer if primary is neuroendocrine carcinoma or neuroblastoma; also some cases of colon carcinoma with resection of hepatic metastases
- Should compare metastatic tumor to prior malignancies
Case reports
- 60 year old woman with female adnexal tumor of probable Wolffian origin metastatic to liver (Arch Pathol Lab Med 2000;124:431)
Gross description
- 90% are multiple, variable size, may replace entire liver and locally elevate the capsule or not be visible on external surface
- Often hemorrhage and necrosis; extensive hemorrhage suggests choriocarcinoma, angiosarcoma or thyroid carcinoma
- Cannot determine malignancy based on gross appearance only
