What is Maffucci Syndrome? Maffucci Syndrome is a rare genetic disorder that affects bones and skin. It is marked by multiple enchondromas, which are benign cartilage tumors, and hemangiomas, which are vascular malformations. These symptoms usually appear in early childhood, often between ages 1 and 5. Enchondromas can cause severe bone deformities, leading to fractures and short stature. Hemangiomas, appearing as red or purplish skin growths, can develop anywhere on the body. Although enchondromas are benign, they can become malignant over time, increasing the risk of chondrosarcoma. Regular monitoring and early intervention are crucial for managing this condition.

Genetic Causes and Inheritance
Understanding the genetic basis of Maffucci Syndrome helps in diagnosing and managing the condition.
-
Genetic Cause: Caused by somatic mutations in the IDH1 or IDH2 genes, which produce enzymes involved in cellular metabolism.
-
Somatic Mutations: These mutations occur during a person's lifetime and are not inherited, meaning the condition appears randomly.
-
Mosaicism: The mutations occur in a single cell, leading to mosaicism as the cell divides and multiplies.
-
Non-Hereditary: The condition is not passed down through families and appears sporadically.
Diagnosis and Treatment
Diagnosing Maffucci Syndrome involves a combination of physical exams, imaging, and sometimes surgery. Treatment varies based on symptoms.
-
Diagnosis: Made through detailed history, physical examination, and radiologic assessment. Surgical removal and microscopic study confirm the presence of enchondromas.
-
Treatment: Varies depending on symptoms. Surgical removal of enchondromas and hemangiomas may be necessary. Sclerosing agents can harden and shrink hemangiomas.
-
Surgical Interventions: Surgery is often needed to remove enchondromas and correct bone problems. Orthopedic surgeons address skeletal issues like leg length differences or spine curvature.
Life Expectancy and Quality of Life
While Maffucci Syndrome can lead to serious complications, many individuals live typical lifespans with proper management.
-
Life Expectancy: Generally typical, though longevity depends on the presence of malignancies or other complications.
-
Physical Impairment: Varies based on individual skeletal deformities. Severe deformities can lead to significant physical impairment.
-
Intelligence: Unaffected in individuals with Maffucci Syndrome. They typically have average intelligence with no associated mental abnormalities.
Additional Health Concerns
Maffucci Syndrome can also affect other parts of the body, leading to various health issues.
-
Cardiac Involvement: Patients may experience cardiac symptoms like recurrent syncope, fatigue, and palpitations due to vascular malformations affecting the heart.
-
Vascular Neoplasms: Besides hemangiomas, vascular neoplasms like hemangiosarcomas and lymphangiosarcomas have been reported.
-
Other Malignancies: Associated with pancreatic and hepatic adenocarcinoma, ovarian tumors, brain gliomas, astrocytomas, and other sarcomas.
Recent Discoveries
New genetic findings continue to shed light on the complexities of Maffucci Syndrome.
- ERC2 Mutation: An additional mutation in the ERC2 gene was identified in 2021, contributing to the development of the condition.
Diagnostic Tools
Accurate diagnosis relies on a combination of imaging and microscopic studies.
-
Radiologic Assessment: Imaging scans like X-rays help identify enchondromas and other bone deformities.
-
Microscopic Study: Surgical removal and microscopic study of skeletal lesions confirm enchondromas and distinguish them from chondrosarcomas.
Managing the Risk of Malignancy
Regular monitoring and early intervention are key to managing the risk of cancer in individuals with Maffucci Syndrome.
-
Chondrosarcoma Risk: Higher in individuals with multiple enchondromas, estimated at 15-40%.
-
Age of Neoplastic Change: The average age for neoplastic change is 40 years, highlighting the importance of regular monitoring.
Distribution and Characteristics of Lesions
Understanding the distribution and characteristics of lesions helps in managing the condition effectively.
-
Lesion Distribution: Enchondromas affect only one side of the body in about 40% of patients. Hemangiomas can occur anywhere but are most common on the hands.
-
Calcification: Hemangiomas may become hard, warty, or knotty and can contain calcium stones over time.
-
Internal Structures: Hemangiomas can also develop in internal structures like the membranes covering the brain and spinal cord, the tongue, and the oral mucosa.
Types of Vascular Malformations
Different types of vascular malformations can occur in Maffucci Syndrome, each with unique characteristics.
-
Spindle Cell Hemangioma: A benign vascular tumor often arises in malformed veins, a type of venous malformation.
