The biopsy looks to see if lymphocytes have infiltrated the salivary glands. There is specific criteria as to the infiltration for a Sjogren's diagnosis. There must be at least one focus (an aggregate of 50 or more lymphocytes, histiocytes, and plasma cells) within a 4 mm sq area for a positive result. There are several doctors that can perform the biopsy (dermatologist, ENT, and oral surgeon are the most common). It's just as important to have someone with experience do the biopsy as it is the pathologist that reads it. It is not a common procedure so ask about experience. I will be honest, many times the biopsy leaves a small numb area in the lower lip and sometimes a small knot as well. They can be permanent. I have both, but they are not bothersome.

Sjogren's can explain the dry eyes, mouth, PN and many other things as well. I don't know if your ophthalmologist told you, but using a small amount of baby shampoo on a washcloth and washing around your eyes can help control the blepharitis.

If you have any questions, ask away. I'll do my best to answer. If you are on the east coast, Johns Hopkins has a good Sjogren's Center.
