- Angiosarcoma (AS) is a rare, aggressive cancer that starts in endothelial cells, often appearing as skin lesions on the head and neck, making it hard to diagnose due to its variable signs.
- An 87-year-old woman had an asymptomatic neck nodule that worsened and was initially misdiagnosed as cellulitis; it did not respond to typical treatments, highlighting the challenges of identifying AS.
- The prognosis for AS is poor, with a 5-year survival rate of around 35%, and treatment often involves a mix of surgery, radiation, and chemotherapy, tailored to the individual's case.
