Hepatoblastoma is a very rare cancerous tumor that originates in the liver. The liver is one of the largest organs in the body. The primary functions of the liver include filtering and storing blood. The liver consists of right and left lobes.
Most hepatoblastoma tumors originate in the right lobe.
This disease primarily affects children from infancy to about 5 years of age. Most cases appear during the first 18 months of life. The most common sites of metastasis are the lungs, into the abdomen and abdominal structures, and rarely to bone, the central nervous system, and the bone marrow. The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm and on top of the stomach, right kidney, and intestines. Shaped like a cone, the liver is a dark reddish-brown organ that weighs about three pounds.
