Juiz de Fora, MG, Brasil. En bloc resection and bone graft: The polyostotic form is rarer and mainly occurring in long bones 610 and possibly associated with McCune-Albright syndrome, which is characterised by the presence of coffee-milk cutaneous pigmentation and endocrinopathy 136 – 1016 World J Surg Oncol.
