ABSTRACT
Several soft tissue tumors arise within and around blood vessels. These may be benign or malignant and may arise around arteries, veins or capillaries.
Hemangioma Hemangiomas are among the most common STT. Most are present at birth, and regress spontaneously. Rapid growth with impingement on vital structures may occur, however, and treatment with intralesional injection of interferon has been life-saving.78 Pulmonary hemangiomatosis, a rare disorder of diffuse microvascular proliferation in the lung, has been treated effectively with systemic interferon. Cavernous hemangioma refers to a benign lesion consisting of large dilated blood vessels with a flattened endothelium.
