Epithelioid hemangioendothelioma arising within the spleen. (a) Axial MRI scan showing liver hemangiomata (white masses) and vascular splenic lesions. (b) Gross specimen following splenectomy. White arrows correspond to imaging findings in (a). (c) H&E staining demonstrated a highly cellular, atypical complex vascular lesion with rare mitotic figures. (d) MIB-1 staining illustrates a proliferation index of approximately 10%. (e) Immunophenotyping with CD31.
