best of my knowledge birthmark wise Dr Vijay Narinesingh? is the closest to anything vascular
try this email for Dr Lalla: email@example.com
and Dr. Lushington firstname.lastname@example.org
Dr Lushington in particular has an organisation that handle some special cases. I met him once when i was attempting to source help for myself.
Dr Lalla seems very knowledgable about birthmarks. I was impress. I don't know if he's still down in sando. i have not been in touch with him for a while. Had no good news to give him but he was very nice. i am not sure what his speciality is.
send a picture and i hope they can help you. or just go to Mt Hope
