Brown tumors developing in renal transplant recipients with persistent hyperparathyroidism: two case reports and review of literature.
BACKGROUND
Brown tumors, evidence for severe hyperparathyroidism, are rare in end-stage renal disease, and are distinctly uncommon in patients with a functioning renal transplant.


METHODS
We report two cases of brown tumors developing after renal transplantation, and discuss their presentation and treatment. We review the literature.


CONCLUSIONS
We suggest that persistent hyperparathyroidism post-renal transplant requires aggressive intervention to avoid significant consequences.
