Glomerulonephritis, MembranousA disease of the glomerulus manifested clinically by proteinuria, and sometimes by other features of the nephrotic syndrome. It is histologically characterized by deposits in the glomerular capillary wall between the epithelial cell and the basement membrane and a thickening of the membrane. Also characteristic are outward projections of the membrane between the epithelial deposits in the form of "spikes". There is some agreement that the deposits are antigen-antibody complexes.
DiseaseA definite pathologic process with a characteristic set of signs and symptoms. It may affect the whole body or any of its parts, and its etiology, pathology, and prognosis may be known or unknown.
