Angiosarcoma

QUESTION 60

A 75-year-old woman is evaluated by the dermatology inpatient consult service for an enlarging growth on her forehead. She states that this area initially started as a small bruise on the right forehead, but rapidly progressed with swelling and the appearance of violaceous, hemorrhagic plaques and nodules with ulceration (60). She also states that it is very itchy and painful. Biopsy revealed infiltration of the dermis by vascular spaces lined by piled-up endothelial cells splitting apart collagen bundles.
