It is composed of a varying admixture of hyaline cartilage that has features resembling growth plate cartilage, fascicles of spindle cells, woven bone, and hemorrhagic cysts. Treatment consists mainly of surgical excision, which is usually curative. We present 3 new cases, which demonstrated interesting findings, including multicentricity, involvement of the sternum, and local recurrence, and we discuss these findings in the context of a literature review.
