I would suggest that you contact Dr. Delfanian, the VBF KT Expert for advice. You might want to include a photo. also. Here is the link: http://www.birthmark.org/expert/ask_the_kt.php
The VBF Vascular Birthmarks brochure has information on KT and other types of birthmarks and related conditions, and can be found here: http://www.birthmark.org/parents_publications.php
There are also a couple of KT organizations that you can check for more information.
Please let me know if there is anything else I can help you with, and please keep us posted on your daughter's condition.
