Primary Scalp Angiosarcoma With Metastasis to the Liver in an Orthotopic Liver Transplant Patient

Angiosarcoma is a rare malignant neoplasm of vascular endothelial cells. A majority are primarily in the skin. Angiosarcoma of the head and neck is the most common form, but only constitutes 0.1% of all head and neck malignancies. We present an extraordinary case of a 71 year-old male six months status post orthotopic liver transplant secondary to end stage liver disease from cryptogenic cirrhosis, who presented to the liver clinic with a rapidly growing scalp tumor and hypodense lesions within the liver. Further work-up and biopsies confirmed the first documented case of primary scalp angiosarcoma with metastasis to the liver in an orthotopic liver transplant patient.
