Am J Surg Pathol. 1979 Oct;3(5):449-55. doi: 10.1097/00000478-197910000-00007.


A case of chondroblastoma involving the left ischium, lower wing of left ilium and inferior ramus of left pubis is presented. The tumor showed aggressive features and repeated recurrences over a 30-year period and ultimately developed the cytologic features of a malignant neoplasm. However, no metastases have developed.
