This condition can be diffused, also. My condition started with Cystic Hygroma of the right axillary. It has progressed slowly to other area's of my body. Experts in this field who could speak better to this are ENT's and Vascular Clinics. The Vascular Clinic at Children's Hospital in Boston has some of the leading EXPERTS on this condition. I would start there with getting your question answered. You can also, google Cystic Hygroma Support and you should receive a link to a site with a guest book running for years on this condition. A lot of people there with the condition and I have posted there with information on another group with other adults with the condition.
