A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma , known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.
Approximately 5% of adults have liver hemangiomas in the United States, but most are asymptomatic. [30] Liver hemangiomas usually occur between the ages of 30 and 50 and more commonly in women. [4] Cases of infantile liver cavernomas are extremely rare. Cavernous hemangioma of the eye is more prevalent in women than men and between the ages of ...
Cavernous hemangiomas (also called hepatic hemangioma or liver hemangioma) are the most common type of benign liver tumor, found in 3%– 10% of people. [2] They are made up of blood clusters that are surrounded by endothelial cells. [5] These hemangiomas get their blood supply from the hepatic artery and its branches. [5]

In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein .
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus. [6] and formerly known as a cavernous hemangioma.
Diagram showing two epithelial tumors. The upper tumor is a benign tumor that is non-invasive. Benign tumors are usually round in shape and encapsulated by fibrous connective tissue. The lower picture depicts a malignant tumor. It is irregularly shaped, vascular, and it is invasive, crossing the basement membrane.
