Rare liver tumors
Liver tumors are gastrointestinal malignancies with increasing incidence. Despite imagining techniques and modern treatment options is the mortality almost the same as morbidity. However, the majority of primary liver tumors are hepatocellular cancer and cholangiocellular cancer, there are plenty of other possible histological types, which can be found in the liver parenchyma. All of them are extremely rare, have different biological behavior and therefore also need individual multidisciplinary approach. Fibrolamellar hepatocellular cancer and mixed hepatocellular-cholangiocellular cancer, are both unusual forms of the most common histological types. Hepatoblastoma is primary the cancer of the childhood, but there are several cases described also in adult population. Sarcomas is one huge subgroup of mesenchymal tumors, including plenty of possible histological types, with a different clinical behavior. Extremely rare are primary liver mucosa-associated lymphatic tissue lymphomas and primary liver neuroendocrine tumors.
