telangiectatic cancer

A nonspecific term for a well-vascularised malignancy (e.g., a carcinoma with dilated blood vessels) or a sarcoma (e.g., Kaposi sarcoma or angiosarcoma).
Telangiectatic cancer is merely a descriptive term and not a pathological entity unto itself; while it is not part of the working medical parlance, it may be used when discussing certain aspects of cancer with patients.
