Maffucci Syndrome

Maffucci syndrome is a rare disorder that affects the bones, skin and blood vessels. The abnormal growths may become cancerous over time. These individuals are also prone to cancer in other parts of the body. Signs of the syndrome may not be evident at birth, but typically manifest by the age of 5. It is not an inherited condition.

Characteristics of the syndrome include:

Multifocal hemangiomas
