Depends what specialty you see. I was told the infiltrates of my biopsy did NOT affect the gland. I have seen at least 10 rheumatologists since 2000 when my biopsy was done and most of them blew off my biopsy. Some looked at it a bit more closely after my ANA went positive.

AAG is definitely a stand alone disease.

Autoimmunity can attack any organ system, but when it attacks the autonomic system, it attacks the control center of the entire body, hence causing a huge amount of symptomotolgy.

Rheumatology has yet to define many of it's diseases very well. Sjogren's is everything from sicca to AAG.
