Maffucci’s Syndrome is a rare, non-hereditary disorder that affects both the bones and skin, often leading to significant physical challenges. It is marked by the presence of multiple enchondromas (benign cartilage tumors) and vascular malformations, such as dark red or purplish skin lesions. These growths can cause deformities, discomfort, and—over time—an increased risk of developing malignant tumors.

Although a diagnosis of Maffucci’s Syndrome can be emotionally overwhelming, with consistent medical care and monitoring, many people are able to manage the condition and maintain a good quality of life.

Causes of Maffucci’s Syndrome

The exact cause of Maffucci’s Syndrome is still unknown, but current research suggests it results from sporadic mutations that occur during early fetal development. These mutations affect the way cartilage and blood vessels develop, leading to the characteristic bone and skin changes.

Unlike some other bone and skin disorders, Maffucci’s Syndrome is not inherited—it occurs randomly and is extremely rare.

Symptoms of Maffucci’s Syndrome

The symptoms of Maffucci’s Syndrome vary from person to person but may include:

  • Multiple enchondromas—benign cartilage tumors in the bones of the hands, feet, or limbs, which may lead to:
    • Skeletal deformities
    • Bone fractures or fractures that heal poorly
    • Uneven limb length
  • Vascular anomalies, such as:
    • Red or purple patches on the skin (often soft and compressible)
    • Soft tissue swelling in affected areas
  • Increased cancer risk:
    • Individuals with Maffucci’s Syndrome have a higher chance of developing chondrosarcoma (a type of bone cancer) and other malignancies, including in the skin, brain, and internal organs.

Treatment for Maffucci’s Syndrome

There is no cure for Maffucci’s Syndrome, but symptoms can be managed with a combination of monitoring and medical intervention:

Non-surgical Management

  • Regular imaging (X-rays, MRIs, etc.) to monitor the size and growth of enchondromas
  • Dermatological evaluations for skin changes or vascular anomalies
  • Physical therapy to maintain mobility and reduce discomfort

Surgical Options

  • Corrective orthopedic surgeries to address deformities, stabilize fractures, or equalize limb length
  • Tumor removal or biopsy if malignancy is suspected
  • Cosmetic procedures for vascular growths that cause discomfort or aesthetic concerns

When to See a Doctor

If you or a loved one has been diagnosed with Maffucci’s Syndrome—or is showing signs such as frequent fractures, bone deformities, or vascular skin growths—consult with a specialist in orthopedics, oncology, or genetic disorders.

Early detection and consistent monitoring are key in reducing complications and improving outcomes for individuals with this condition.
