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.
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
Benign tumors of bone can be similar macroscopically and require a combination of a clinical history with cytogenetic, molecular, and radiologic tests for diagnosis. [23] Three common forms of benign bone tumors with are giant cell tumor of bone, osteochondroma , and enchondroma ; other forms of benign bone tumors exist but may be less prevalent.
Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
Hepatic hemangiomas are the most common site for internal organ damage. Hepatic hemangiomas may be difficult to identify, because it can be inaccurately diagnosed as a hyper-vascular malignancy. These malignancies can live alongside other liver tumors such as hepatic cysts, hepatic angiosarcoma, focal nodular hyperplasia, and a myriad of others.
Hemangioma Hemangioma is a benign vascular tumor of the endothelial cells of blood vessels. Too much endothelial cell growth typically leads to a messy clump of blood vessels, all filled with blood, similar to Kaposi sarcoma. The tumor is usually found on the skin, but can happen pretty much anywhere.
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]
Cavernous hemangiomas are erroneously called the most common benign tumors of the liver. [14] Usually one malformation exists, but multiple lesions can occur in the left or right lobe of the liver in 40% of patients. [3] Their sizes can range from a few millimeters to 20 centimetres. Those over 5 cm are often referred to as giant hemangiomas. [3]
