Introduction: Tumors in bone marrow are usually hematolymphoid or epithelial in origin. Metastatic sarcoma to bone marrow is relatively rare. Angiosarcoma is an uncommon malignant sarcoma of endothelial cells in origin, and principally spread hematogenously. Lung is the most common site for metastases, and other rarer sites for metastases include liver, lymph nodes, and the brain . Metastasis to bone marrow is rarely reported.
Case Report: This is a case of bone marrow involvement by metastatic angiosarcoma in an 80-year-old Chinese man. He presented with persistent thrombocytopenia few years after the diagnosis of angiosarcoma at the scalp and temporal region. The case is described with a review of literature. Clinical information, histological and immunohistochemical features are described. Histological exam of the bone marrow trephine biopsy confirmed the diagnosis of metastatic angiosarcoma.
Conclusion: Angiosarcoma is a highly aggressive vascular neoplasm. In patients with known history of angiosarcoma, clinicians should always bear in mind the possibility of bone marrow metastasis as the cause of persistent thrombocytopenia. Prompt investigations including bone marrow trephine biopsy should be performed.
Keywords: Angiosarcoma, Bone marrow, Metastasis
