A malignant neoplasm occurring in young children, primarily in the liver, composed of tissue resembling embryonal or fetal hepatic epithelium, or mixed epithelial and mesenchymal tissues. A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested. (HEP-a-toe-blas-TOE-ma) A type of liver tumor that occurs in infants and children. Hepatoblastoma is a malignant liver neoplasm that occurs almost exclusively in infants, although isolated instances in older children and adults have been reported. Grossly, hepatoblastoma is solid, well circumscribed, and more often solitary than multiple. Microscopically, most of the tumors are composed exclusively of immature hepatocytic elements. About a fourth of hepatoblastomas contain a stromal component which may be undifferentiated or develop into bone or cartilage. The treatment of choice of hepatoblastoma is surgical excision with adjuvant therapy. Liver transplantation is being increasingly used as well. --2002 (hep-a-TOE-ma) A liver tumor. A malignant tumor that arises from hepatocytes. Hepatocellular carcinoma is relatively rare in the United States but very common in all African countries south of the Sahara and in Southeast Asia. Most cases are seen in patients over the age of 50 years, but this tumor can also occur in younger individuals and even in children. Hepatocellular carcinoma is more common in males than females and is associated with hepatitis B, hepatitis C, chronic alcohol abuse and cirrhosis. Serum elevation of alpha-fetoprotein occurs in a large percentage of patients with hepatocellular carcinoma. Grossly, hepatocellular carcinoma may present as a single mass, as multiple nodules, or as diffuse liver involvement. Microscopically, there is a wide range of differentiation from tumor to tumor (well differentiated to poorly differentiated tumors). Hepatocellular carcinomas quickly metastasize to regional lymph nodes and lung. The overall median survival of untreated liver cell carcinoma is about 4 months. The most effective treatment of hepatocellular carcinoma is complete resection of the tumor. Lately, an increasing number of tumors have been treated with liver transplantation. --2002 155.0 is a specific code that can be used to specify a diagnosis 155.0 contains 26 index entries View the ICD-9-CM Volume 1 155.* hierarchy Alternate Terminology Carcinoma: liver, specified as primary hepatocellular liver cell Hepatoblastoma  Index entries containing 155.0: Cancer (M8000/3)-see also Neoplasm, by site, malignant hepatocellular (M8170/3) 155.0 Carcinoma (M8010/3) - see also Neoplasm, by site, malignant bile duct type (M8160/3) and hepatocellular, mixed (M8180/3) 155.0 embryonal (M9070/3) liver 155.0 hepatic cell (M8170/3) 155.0 hepatocellular (M8170/3) 155.0 and bile duct, mixed (M8180/3) 155.0 hepatocholangiolitic (M8180/3) 155.0 liver cell (M8170/3) 155.0 Cholangiocarcinoma (M8160/3) and hepatocellular carcinoma, combined (M8180/3) 155.0 Cholangiohepatoma (M8180/3) 155.0 Embryoma (M9080/1) - see also Neoplasm, by site, uncertain behavior liver (M8970/3) 155.0 malignant (M9080/3) - see also Neoplasm, by site, malignant liver (M8970/3) 155.0 Hepatoblastoma (M8970/3) 155.0 Hepatocarcinoma (M8170/3) 155.0 Hepatocholangiocarcinoma (M8180/3) 155.0 Hepatoma (malignant) (M8170/3) 155.0 benign (M8170/0) 211.5 congenital (M8970/3) 155.0 embryonal (M8970/3) 155.0 Kupffer cell sarcoma (M9124/3) 155.0 Sarcoma (M8800/3) - see also Neoplasm, connective tissue, malignant Kupffer cell (M9124/3) 155.0 Teratocarcinoma (M9081/3) - see also Neoplasm, by site, malignant liver 155.0 Teratoma (solid) (M9080/1) - see also Neoplasm, by site, uncertain behavior embryonal (M9080/3) - see also Neoplasm, by site, malignant liver 155.0 liver (M9080/3) 155.0 adult, benign, cystic, differentiated type, or mature (M9080/0) 211.5 malignant (M9080/3) - see also Neoplasm, by site, malignant liver (M9080/3) 155.0 Tumor (M8000/1) - see also Neoplasm, by site, unspecified nature embryonal (mixed) (M9080/1) - see also Neoplasm, by site, uncertain behavior liver (M9080/3) 155.0 mesodermal, mixed (M8951/3) - see also Neoplasm, by site, malignant liver 155.0
