Angiosarcoma

rare malignant tumour arising from the endothelial cells of almost any organ, including the skin. The scalp is a common site of origin. This tumour is also called haemangiosarcoma. Angiosarcomas are rapidly growing neoplasms and tend to grow deeply into adjacent soft tissues, invading bone and cartilage. The prognosis is poor. On CT and MRI these tumours appear as aggressive, well-enhancing mass lesions. Kaposis sarcoma is a variant of angiosarcoma.
