What are the signs and symptoms of a cystic hygroma?

A cystic hygroma is a noncancerous (begnin) mass. It often appears as a painless soft bulge under the skin, however it can bleed or become infected, which may cause the mass to enlarge and cause pain. A viral or bacterial infection may also cause swelling. A potentially serious complication of cystic hygroma in the neck area, is airway restriction or blockage.[1]
