@annieecruz – Good morning. Do you know what is causing this? Or are you asking for someone else? I'm not familiar with this particular disease. I'm a lung cancer survivor of 21+ years.
This is what I could find:
https://www.mayoclinic.org/diseases-conditions/chronic-granulomatous-disease/symptoms-causes/syc-20355817
I am hoping that anyone else in this group who is familiar with this can help you find a doctor.

Hello, @annieecruz – the information that @merpreb provided, https://www.mayoclinic.org/diseases-conditions/chronic-granulomatous-disease/symptoms-causes/syc-20355817, includes a section on doctors and departments at Mayo Clinic, which may be helpful in getting the information you asked about related to who treats granulomas at Mayo Clinic.
