We found a greater gene expression of the inflammatory cytokine markers CD68 (monocytes/macrophages) and CD117 (mast cells/stem cell) in the CAH adrenal and myelolipoma compared to the normal adrenal, suggesting that inflammation may play a role in the poorly controlled CAH adrenal and possibly in the formation of myelolipoma. Here, CD68 is linked to congenital adrenal hyperplasia.
