Spontaneous and fast growing cluster of Hemangioma

My grandaughter is 10 and a hemangioma formed on her shoulder within six weeks to the size of a large egg, It becane necrotic on the outside yetcontinued to growfrom a small base of about t/4 inch in diameter. The growth would bleed off and on and hurt her as well as having a foul odor because of the dying portion. We finally found a pediactric plastic sergeon to remove it at Loma Linda Childrens hospital, At first the incision healed as normal, then, small red raised dots began forming all around where the scar tissue was and now there are at least ten new hemangiomas growing all getting larger and raised up from the skin like little  peas in size, when they first appeared they were only pink dots on her back. How can these be removed so they don;t come back as they are uncomfortabke, itch and bleed. Where would be a good place ro go?  Thank you for considering this.

Thank you

I would also like to ask, what is the normal cause of hemangiomas that suddenly appear first on at age 9, not there at birth, and is there anything to stop more from growing (there are now 34 spots, specks and about 12 are 3 dimensional up to pea sized? How can they be removed permanently?

Thank you very, very much. It took visits to three different doctors who all said they would get back with us (never did) then finally the emergency room visit to Loma Linda when the first one was the size - literally - of an egg perched on her shoulder blade that was necrotic/bleeding on the outside and still growing from the inside,  to find someone who was willing to remove it. That doctor has now finished his residency and is no longer there.
