Syringoma, a non-cancerous bump or clusters of bumps that is caused by an overgrowth of cells within the sweat glands, can be inherited and often runs in families. It also may occur in patients with Down's syndrome, Marfan syndrome or Ehlers-Danlos syndrome. Typically, syringomas develop in young adulthood but can occur at any age. Additionally, individuals of Asian or African American decent are at a higher risk of developing eruptive syringomas, which appear abruptly in adulthood. Diabetics are also at a higher risk of developing clear-cell syringomas. Currently, there there aren't any ways to prevent syringoma if you have a genetic predisposition for the condition. Also, the causes of the condition are poorly understood, and therefore, few preventative measures can be taken.
