I truly believe the problem is that granuloma is treated as a skin condition when it is NOT a skin condition. It is a blood condition like left-shift Leukocytosis (increased white blood cells). There have been no direct studies that I know of but I do know that a dermatologist can not cure it. Perhaps a hematologist can treat the Leukocytosis and that will cure the symptom, I.e., the white blood cells clumping up to the surface of the skin appearing as a rash.
