Splenic Angiosarcoma Diagnosed on Bone Marrow Biopsy: Case Report and Literature Review.

Primary splenic angiosarcoma carries a poor prognosis and is among the rarest forms of malignancy. An overwhelming majority of patients with splenic angiosarcoma will develop metastases. However, osseous metastatic disease is rare. We present an 83 year old hispanic female who was diagnosed with primary splenic angiosarcoma on bone marrow biopsy performed for a hematologic workup. We highlight key historical, laboratory, imaging, and pathological features of splenic angiosarcoma. The synthesis of both imaging features and clinical history is essential for establishing early diagnosis in these patients.
