Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare form of liver cancer that typically affects young adults with no prior liver disease. FL-HCC is characterized by fibrous tissue and cancerous cells forming a distinct mass in the liver, which can lead to a range of symptoms including abdominal pain, nausea, and jaundice. There are no true synonyms for FL-HCC, as the term specifically refers to the unique combination of fibrous tissue and cancerous cells found in this type of liver cancer. However, some related terms may include hepatic fibrosis, hepatic carcinoma, and liver cancer.
