Image Description
Primary cutaneous angiosarcoma that is not associated with radiation or lymphedema is the most common form of angiosarcoma and accounts for about 50% of all cases.
Clinical Features: Most patients are elderly Caucasians. The usual locations are scalp, forehead, face, and neck. The lesions appear as multifocal, ill-circumscribed bruise-like red-purple plaques or papules. High-grade tumors, especially in advanced stages, show induration, nodularity and ulceration and bleed readily. The tumor is frequently larger than is clinically apparent.
