I would sugest that you contact Dr. Waner in NYC. I don't know if he could do this himself or if he would need to refer you to someone else. Also, you may try the Ask A Doctor here on this site. Here is the link http://www.birthmark.org/ask_the_doctor.php
TO find it on the site go to the HOME Page and click on contact the VBF. THen click on Ask A Doctor. I am sorry that I could be more help.
