Abstract

Epithelioid Angiosarcoma (EA) is an extremely rare and highly aggressive malignant tumor. It comprises <1 % of all soft tissue sarcomas and is associated with a poor prognosis. In this case report, we are reporting an 85-years-old male who presented with lower back and left hip pain. A computerized tomography (CT) of the lumbar spine and left hip showed a significant fracture of lumbar spine L3 and osteolytic lesions involving the left hip and femur. The patient underwent L1-L5 fusion with cement augmentation and biopsy of L3. Surgical pathology showed a metastatic undifferentiated tumor of unknown primary origin. Histologic analysis of the specimen and immunohistochemistry confirmed EA. Given extensive diffuse bone involvement, our patient was not a candidate for definitive surgical treatment.
