PRIMARY OBJECTIVE:~I. To determine the accuracy of depicting extent of disease of cutaneous angiosarcoma before and after neoadjuvant treatment compared to clinical photographs, magnetic resonance imaging (MR) or positron emission tomography (PET)/computed tomography (CT) imaging and surgical pathology both on skin biopsies and surgical excision.~OUTLINE:~Patients undergo microvessel ultrasound imaging on study.
This study evaluates the accuracy of a new ultrasound technology called microvessel imaging for detecting the extent of disease among patients with angiosarcoma of the skin. Microvessel ultrasound imaging uses high frequency waves to visualize vessels in the skin that are not easily seen using other imaging tests.
