Flashcards in 62. Other liver tumors Deck (10):
Liver tumor that biopsy is contraindicated ( and why )
cavernous hemangioma ---> risk of hemorrhage metstasis
cavernous hemangioma - frequency / behavior / epidimiology
common , benign liver tumor typically occurs at 30-50 ( NO BIOPSY --> hemorrhage)
liver angiosarcoma - definition / risk factors
mallignant tumor of endothelial origin asociated with arsenic, vinyl chloride
hepatic adenoma - definition/ risk factors
rare, benign liver tumor, often related to oral contraceptive or anabolic steroid use
Hepatic adenoma - course
may regress spontaneously or rupture ( abdominal pain and shock)
• Under what circumstances would a liver biopsy for a patient with a liver tumor be contraindicated?
If the tumor is thought to be a cavernous hemangioma due to potential aspiration causing a life-threatening hemorrhage
• A patient on oral contraceptives is discovered to have a benign liver tumor. What is she most likely to have?
• A patient often works with arsenic and polyvinyl chloride. He is found to have a malignant liver tumor. What liver tumor do you suspect?
• A patient on anabolic steroids has a benign liver tumor. What are two outcomes for this tumor?
The tumor (a hepatic adenoma) either can regress spontaneously or can rupture, causing abdominal pain or shock
