The benign conditions (reactive hyperplasia and lymphadenitis) are usually categorized by the various etiologic factors responsible for adenopathies. Other responses to antigenic stimuli include granulomatous reactions, deposition of interstitial substances, extensive necrosis, plasmacytosis, eosinophilia and formation of immunoblasts. Lymphoid hyperplasia includes follicular hyperplasia (stimulation of B-cell component), paracortical hyperplasia (stimulation of the T cells in the paracortex), histiocytic hyperplasia (mononuclear phagocyte system, including phagocytic histiocytes) and mixed pattern. An infectious agent is usually present in lymphadenitis whereas lymphoid hyperplasia is secondary to antigenic stimulation without infectious etiology. Benign lymphoid lesions include both lymphoid hyperplasia and lymphadenitis. Antigenic stimulation can result in proliferation of B or T cells, sinus histiocytes or specialized cells with the expansion of their corresponding anatomical compartments with subsequent nodal enlargement. At least I know what it feels like now, because I have about 5 more left.The lymph node processes and presents various antigens to either B or T lymphocytes. I kept it to show my doc, but that has to be what it was! I didn’t take pain meds or anything, but the pain inside while it was passing was bad enough I had to lay down for hours, and my lower back hurt the worst. Anyway, there was a black stone in the toilet. ![]() When I finally had to really go, I went and for about 20 seconds, it stung really bad like a cath coming out. I went to the store, bought a bunch of real lemonade and lemons, and chugged a huge glass of that. I guess the pain must have been it passing into my bladder, because when it got to my bladder, it felt like someone was taking a large pin and poking me. I knew I had stones in my kidneys, but never passed one. I thought I was gonna have to go to the ER. My lower back hurt, my entire right side. I was in so much pain for about 2 or 3 hours. Stones this size are not commonly seen intact anymore as most are now treated percutaneously and broken up before being removed.įile photo of another large “staghorn” stone removed by open surgery. The various parts of this stone fill up an entire kidney’s central collecting system, giving it a characteristic shape appearing similar to a deer’s antlers. These have a “jackstone” appearance.įile photo of a large “staghorn” kidney stone removed intact by open surgery.
