Pathologic assessment identified 13 cases of solitary fibrous tumor\/hemangiopericytoma (43.3%) and 7 cases of Ewing's sarcoma\/primitive neuroectodermal tumor (23.3%). Two cases (6.7%) were of metastasis. Other lesions included a single case each of non-Hodgkin's lymphoma, undifferentiated sarcoma, solitary plasmacytoma, and granulocytic sarcoma.
