Granulomatous inflammation of the inner half of the media centered on the internal elastic membrane.  . Left atrium round thrombus. and thrombotic masses. Thromboendocarditis (H.DEGENERATIVE SYSTEMIC CONNECTIVE TISSUE PATHOLOGY Microspecimens  59.E. In the cytoplasm of glomerular endothelial cells tubuloreticular inclusions can be seen. This process can lead to fibrinoid necrosis. 19. similar to the changes seen in other glomerulopathies with nephrotic syndrome. . Fragmentation of the internal elastic lamina. Glomerulonephritis in SLE. and central necrosis. Diffuse cardiosclerosis. Periarteritis nodosa (H. It has a circumscribed collection of mononuclear inflammatory cells.Accumulation of glycosaminoglycans among collagen fibres with their subsequent swelling. • Nodular thickenings with reduction of the lumen. are more evident.E. Fibrinoid intumescence of the connective tissue.). Collagen fibers retain their normal structure and transverse strip (mucoid edema. with waved aspect and intersections. including some large histiocytes with prominent nucleoli and a prominent binuclear histiocyte. regularly curved and spaced deposits. there are seen like parallel.E. it is believed that they are an effect of the interferon. In podocytes we can see effacement of podocyte foot processes. Thrombosis. Macrospecimens       Rheumatic mitral malformation.). • valvulitis. mixomatosis). inflammatory infiltration and edema in the stroma of the valves with superimposed presence of rheumatic vegetations. interfibrilare spaces are considerably wider. With this technique some small subendothelial deposits. but they are extensive and predominant only in class V lesions. and they can also be seen in HIV and renal allograft rejection. . they are not specific of lupus nephritis. Rheumatic granulomatous endocarditis (H.  Electronomicrography  18. • Microscopic appearance of Aschoff body. Fibrinous pericarditis. in classes II and V. Electron dense deposits are demonstrated with a distribution similar to the one of the immune deposits. some subepithelial deposits are evidenced in many cases.). Nonbacterial verrucous endocarditis Thromboendocarditis.  125. these structures are similar to the described ones in cryoglobulinemia and seem to correspond to cryoglobulins.Irreversible disarrangement of connective tissue characterized by destruction of the fundamental substance and collagen fibers and fibrinoid formation.
