Approach Considerations

The lead physician must conduct regular physical examinations and monitor for any changes that may suggest the development of chondrosarcomas, the most common neoplasm in this syndrome.

Radiologic evaluation of suspicious areas should be conducted. Evidence of malignant transformation includes cortical destruction, endosteal cortical erosion, and zones of lucency within a previously mineralized area. Note the image below.

A biopsy should then be performed on suspicious radiologic areas. Needle biopsy should provide a diagnosis. Bone biopsy may be needed if the enchondroma is undergoing any changes.

CT and/or MRI can help in the evaluation of the lesion and its surrounding soft tissue.

Chondrosarcomas, the most common malignant neoplasm associated with Maffucci syndrome, are diagnosed by poorly differentiated pleomorphic chondrocytes. [11, 12]
