focal glomerulonephritis

fo·cal glo·mer·u·lo·ne·phri·tis

glomerulonephritis affecting a small proportion of renal glomeruli that commonly presents with hematuria and may be associated with acute upper respiratory infection in young males, not usually due to streptococci; associated with IgA deposits in the glomerular mesangium and may also be associated with systemic disease, as in Henoch-Schönlein purpura.

Thus, it appears that in majority of cases of chronic focal glomerulonephritis, there are diffuse intercapillary deposits associated with the focal lesions.
He had undergone kidney transplantation more than 20 years previously following the diagnosis of focal glomerulonephritis. Renal function was stable under immunosuppressive therapy with cyclosporine A (CSA) and the patient was usually normotensive.
Although on light microscopic examination, histologic features such as proliferative glomerular lesions and necrotizing or crescentic lesions may be focal (focal glomerulonephritis) with some glomeruli being normal, on IF and EM examination, usually immune complex deposition is diffuse and involves even the light microscopically normal-appearing glomeruli.
