Description
Anna-Sophia Leven and co-authors report two cases of a rare skin cancer in a 2026 paper. Cutaneous angiosarcoma grows fast, spreads early, and makes up only a small share of soft tissue cancers. On the head and neck it is hard to treat, and five-year survival is low even with surgery, radiation, and drug treatment together.
Both patients had wide disease on the scalp. They received an immune drug that blocks the PD-1 checkpoint, paired with radiation. In both cases the cancer cleared fully. The authors note why this cancer may respond to immune drugs: it carries many mutations and often shows the very markers those drugs target. The cases suggest a path for patients who cannot have wide surgery.
