Bone marrow is an exceptionally uncommon site of metastatic dissemination in angiosarcoma (AS) as only single case reports have been published so far. We report a case of a 72-year-old male with epithelioid angiosarcoma of the liver who subsequently developed erythroblastic anemia. The trephine bone marrow biopsy revealed total replacement of the normal hematopoiesis by diffuse infiltrate of AS. This rare complication of the clinical course of this tumor should be taken into account in the pathological diagnosis of patients with AS presenting with hematological abnormalities.
