Angiosarcomas are uncommon, high-grade malignant tumors of endothelial cell origin that can arise via the lymphatics or vasculature. They typically occur spontaneously; however, there have been cases reported of benign vascular transformation. These tumors are more commonly found in elderly men on the head and neck in sun-damaged skin. . This is a late complication, typically occurring about 5-10 years after radiation. Stewart-Treves syndrome, chronic lymphedema occurring after breast cancer treatment with axillary node dissection, increases the risk of angiosarcoma. As a vascular tumor, angiosarcoma spreads hematogenously and carries a poor prognosis if not caught early. Differential diagnoses include other vascular tumors such as retiform hemangioendothelioma. In this specific patient, the differential diagnosis includes Paget’s disease, chronic radiation skin changes, and eczema.
Histopathologically, angiosarcomas exhibit abnormal, pleomorphic, malignant endothelial cells. As the tumor progresses, the cell architecture becomes more distorted and cells form layers with papillary projections into the vascular lumen. Malignant cells may stain positive for CD31, CD34, the oncogene ERG and the proto-oncogene FLI-1. Histology in this patient revealed radiation changes in the dermis, as well as few vascular channels lined by large endothelial cells with marked nuclear atypia, in the form of large nucleoli and variably coarse chromatin. The cells were positive for MYC.
Treatment of angiosarcoma involves a multidisciplinary approach. Resection with wide margins is generally the treatment of choice. However, recurrence is relatively common, which may be a result of microsatellite deposits of the tumor. Perioperative radiation is recommended, and adjuvant chemotherapy often is recommended for metastatic disease. Specifically, paclitaxel has been found to promote survival in some cases of cutaneous angiosarcoma. Metastatic disease may be treated with cytotoxic drugs such as anthracyclines and taxanes. Additionally, targeted therapy including anti-VEGF drugs and tyrosine kinase inhibitors have been tested.
The case and photo were submitted by Mr. Shapiro of Nova Southeastern University College of Osteopathic Medicine, Fort Lauderdale, Fla., and Dr. Bilu Martin. The column was edited by Dr. Bilu Martin.
