Abstract
A splenic tumor is reported with the light microscopic, immunohistochemical, and ultrastructural features of a hemangiopericytoma. The findings in this case are compared with the only previously reported splenic hemangiopericytoma. Differences in the clinical presentation and the gross appearance of the two cases are described, and similarities in the microscopic features are discussed.
