Maffucci syndrome

What is Maffucci syndrome?

Maffucci syndrome is a disorder that primarily affects the bones and skin. It is characterized by multiple enchondromas (benign enlargements of cartilage), bone deformities, and hemangiomas (tangles of abnormal of blood vessels). The abnormal growths associated with Maffucci syndrome may become cancerous (malignant). In particular, affected individuals may develop bone cancers called chondrosarcomas, especially in the skull. They also have an increased risk of other cancers, such as ovarian or liver cancer. The underlying cause of Maffucci syndrome is unknown. No specific genes related to this disorder have been identified. Researchers suggest that the condition may be associated with abnormalities occurring before birth in the development of two embryonic cell layers called the ectoderm and the mesoderm.

How might Maffucci syndrome be treated?

Management aims at relief of symptoms and early detection of malignancies.

Individuals with Maffucci syndrome may benefit from consultations with the following specialists:

  • Radiologist: Radiography or CT scanning performed periodically to evaluate bone changes.
  • Orthopedic surgeon: An orthopedic surgeon may be consulted to evaluate bone changes and skeletal neoplasms and to help in treatment of fractures associated with the disease.
  • Dermatologist: A dermatologist may be consulted to evaluate hemangiomas associated with the condition and to identify any new lesions on the skin.
