Matthew Shared "Musculo- Dermatology" - 21 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.

Angiosarcoma
- Rare blood vessel malignancy typically occurring in the head, neck, and breast areas. Endothelial origin.
- Usually in elderly, on sun-exposed areas.
- Associated with radiation therapy and chronic postmastectomy lymphedema.
- Hepatic angiosarcoma associated with vinyl chloride (like in PVC pipes) and arsenic exposures. Also associated with Thorotrast exposures.
- Very aggressive and difficult to resect due to delay in diagnosis
- Usually asymptomatic, may have RUQ pain or may impinge on nearby structures; excellent prognosis with resection
