An Update on Cutaneous Angiosarcoma Diagnosis and Treatment

Cutaneous angiosarcoma (CAS) is a rare aggressive malignancy that most commonly manifests in White men older than 60 years and often appears as an enlarging ecchymosis on the head, neck, or scalp. Surgery with negative margins is the first-line treatment. The role of Mohs micrographic surgery (MMS) is uncertain but can be used in smaller, well-circumscribed lesions on the head and neck. The greatest impact that dermatologists can have in the management of CAS is through a thorough total-body skin examination and heightened awareness resulting in a shortened time to diagnosis. Until quality evidence allows for the creation of consensus guidelines, multidisciplinary care at a cancer center that specializes in rare difficult-to-treat tumors is essential in optimizing patient outcomes.
