What Is Maffucci Syndrome?

Maffucci syndrome is an extremely rare genetic disorder characterized the development of multiple enchondromas (benign cartilage tumors) and hemangiomas (benign blood vessel tumors) in the bones and skin, respectively. First described in 1881 Angelo Maffucci, this syndrome primarily affects children and typically presents in early childhood or infancy.

The exact prevalence of Maffucci syndrome is unknown due to its rarity, but it is estimated to occur in less than 1 in every 100,000 individuals. Both males and females can be affected equally. The syndrome has been reported in various ethnicities and geographical locations, suggesting that it is not associated with any specific population.

Individuals with Maffucci syndrome typically experience the simultaneous development of multiple enchondromas and hemangiomas. Enchondromas usually occur within the long bones of the limbs, such as the femur and tibia, but can also affect the bones of the hands, feet, and spine. These benign tumors can cause bone deformities, growth disturbances, and an increased risk of fractures. They may also become malignant (chondrosarcomas) in rare cases, necessitating careful monitoring and medical intervention.

Hemangiomas, on the other hand, are characterized abnormal growth of blood vessels. They can appear as soft, raised masses on the skin with a reddish or bluish coloration. Hemangiomas associated with Maffucci syndrome can be found in various locations, including the skin, mucous membranes, internal organs, and even the brain. The presence of these tumors can lead to complications such as bleeding, pain, and functional impairments depending on their size and location.

The exact cause of Maffucci syndrome is still unknown, but it is believed to be a result of somatic mutations in the IDH1 or IDH2 genes. These genes encode enzymes that play a crucial role in cell metabolism. When mutations occur in these genes, it disrupts the normal processes of the cells and results in the development of enchondromas and hemangiomas.

Maffucci syndrome is generally considered to be a sporadic condition, meaning that it typically occurs in individuals with no family history of the disorder. However, in rare cases, familial patterns have been observed, suggesting a possible genetic predisposition.

Diagnosing Maffucci syndrome can be challenging due to its rarity and the non-specific nature of its symptoms. A thorough physical examination, radiological imaging, and biopsy of the tumors are usually required to confirm the diagnosis. Genetic testing may also be helpful in identifying the specific mutations in the IDH1 or IDH2 genes.

There is currently no cure for Maffucci syndrome. Treatment focuses on managing symptoms, preventing complications, and surveilling for potential complications, such as malignant transformation of enchondromas. Close monitoring a multidisciplinary team, including orthopedic surgeons, dermatologists, radiologists, and geneticists, is essential to ensure optimal management of the condition.

Surgical intervention may be necessary in some cases to remove or stabilize the tumors, relieve pain, or correct bone deformities. However, surgery carries the risk of complications and should be carefully considered on an individual basis.

Regular follow-up with healthcare professionals is crucial to monitor the progression of the disease and address any emerging symptoms or complications promptly. Psychological support for patients and their families is also important to cope with the challenges associated with Maffucci syndrome.

Maffucci syndrome is an exceedingly rare genetic disorder characterized the simultaneous development of multiple enchondromas and hemangiomas. Its exact cause remains unknown, but it is believed to result from somatic mutations in the IDH1 or IDH2 genes. Diagnosis can be challenging, and treatment revolves around symptom management and surveillance. Maffucci syndrome requires a multidisciplinary approach, including regular follow-up and psychological support, to ensure the best possible care for affected individuals.
