It is characterized by the presence of spindle-shaped or stellate chondrocytes, a lobulated growth pattern, myxoid stroma formation, and sometimes multinucleated giant cells. It has been associated with chromosomal rearrangement of 6q13 and 6q25 bands. The most common clinical symptom is mild, localized pain."
