Ossifying chondrolipoma of the thigh: radiographic pathologic correlation

Lipomas are the most common benign soft-tissue tumors occurring in the subcutis or muscular regions. Histologically, lipoma consists of mature adipose cells, similar to normal adipose cells. Lipomas can occasionally have areas of bone or cartilage formation and are classified as osteolipomas or chondrolipomas, respectively.1,2 However, there have been few reported cases of lipoma with both ossification and cartilage formation.3,4 Here, we report an extremely rare case of ossifying intramuscular chondrolipoma in the thigh and review its radiographic and pathologic correlation. According to the guidance of the local institutional review board, the patient and her guardian provided informed written consent.
