Role of electronmicroscopy in the classification of lupus nephritis

The role of transmission electronmicroscopy in the clarification of the pleomorphic lesions of lupus nephritis is reviewed. Emphasis is placed on the WHO classification of glomerular lesions and in the importance of electronmicroscopy, particularly the precise identification of the milder forms of glomerular involvement. This is essential for the proper therapeutic management of patients with lupus nephritis and to establish a more accurate prognosis.
