Dear Dee,
I hope the following helps you a bit and maybe some other folks who might be wondering the same thing as well. The info I provide is strictly based on my medical experience and reference materials...so for any serious clarification, your doc might have more specific guidance geared towards YOUR specific case!
Chronic rheumatoid arthritis patients often get rheumatoid pannus (nodules).
These pannus are basically inflammed synovial (synovial=joint fluid) granulation tissue. These rheumatoid nodules are firm, under the skin masses typically found in areas like the extension of your forearm, elbows, and over areas where there is pressure.
If you were ever to look @ one in a biopsie...it's kinda looks like a tapioca pudding bead!!! Just thought that would be a good visual and explanation! hee hee.
How do they form?
We know that with RA, our joints and their fluids are inflammed. In a joint, there is a synovial membrane (a joint capsule) which is responsible for producing the fluid that lubricates our joints. This membrane hypertrophies (gets real thick) over time due to all of this inflammation.
So now we have a very thick "helmut" thingy on the joint of a systemic RA pt...with all the inflammation going on, the blood supply isn't so great. Some areas of this thick "helmut" get blocked off from O2 and blood, and then they kinda "scab" up, or a process called granulation. { I.E. Say for instance you're making a pot roast...after cooking for a long time, you get these burnt crusties that fall off and they make great gravy! Kinda the same process going on! }
Now these pannus gradually float away or extend from the thick joint membrane and we can then see and feel them under the skins surface.
WHERE THE HECK DO I GET MY ANALOGIES FROM? I HAVE NO IDEA!! LOL
RA pannus can also form in other places like the eye (cornea).
They may form in places like the heart, lungs, and spleen too.
Some nodules can be very thick, opaque, painful. They are called Crassus. They hurt because they are getting a lot of blood. (kinda like how a new bruise or cut hurts real bad...all the blood is there making it painful).
Pannus can also be in areas that are very very dry, in excema, rosacea for example. This is called Siccus pannus and the nodule is not vascularized or it's poorly vascularized.
So what do we do now?? We've got these annoying painful balls under our skin.
We treat them with our RA meds; pain meds if they are painful; topical anesthetics; application of heat or ice; paraffin dips; removal if absolutely necessary.
Has your primary doc seen them?? If it is very bothersome to you...be persistant. Keep an eye on them to watch for anything abnormal...like growth, change in color, etc...to be sure you know that that's what you are dealing with and not anything like calcium deposits or fatty tumors or other stuff.
In closing...these little buggers are a good way in diagnosing RA! It is a good tell tale sign...just to leave ya on a positive note.
Well, I hope this comes in handy & puts your mind at ease. Many many people have them and it's part of RA.
Let me know if I can try to find out anything more.
I wish you well & take good care!
Sincerely,
