User:Mr. Ibrahem/Vascular tumor

Vascular tumors are a type of growth that forms from cells that make blood vessels or lymph vessels. In around 30% of cases they are visible at birth while most of the rest form later in childhood. Many will grow and than resolve spontaneously. Symptoms may include bleeding or pain. Complications of some types include blood-clotting problems.

The most common type is infantile hemangioma. Other types include congenital hemangioma, tuft angioma, pyogenic granuloma, angiofibroma, lymphangioma, hemangioendothelioma, Kaposi sarcoma, and angiosarcoma. They can be benign or cancerous. Diagnosis is by examination, medical imaging, and occasionally biopsy.

Treatment depends on the specific type of tumor. Options may range from observation, to beta blockers, steroids, photocoagulation, embolization, surgery, radiation therapy, or chemotherapy. NSAIDs may be used to help with pain.

Infantile hemangiomas occur in about 5% of babies. Other vascular tumors are rare. Lymphangiomas representing about 4% of vascular tumors. Vascular tumors were historically described as "birthmarks". In the mid 1800s Rudolf Virchow created the first classification system, while the current classification system was originally proposed in 1982.
