    Abstract:
    A 74-year-old man was admitted to our hospital because of a treatment for his right renal tumor. The abdominal CT scanning revealed a mass in the right kidney, and a right selective renal arteriography demonstrated a hypervascular tumor. On admission, urinalysis revealed proteinuria (3-4 g/day) and microscopic hematuria, and serum electrolytes were normal. Serum creatinine and urea nitrogen levels were 1.6 mg/dl and 30 mg/dl, respectively. A percutaneous right renal biopsy specimens showed crescentic glomerulonephritis. Direct immunofluorescence studies showed strong linear staining for IgG and IgA along the glomerular capillary walls. Electron microscopy showed increased mesangial matrix and swollen epithelial cells, but no dense deposits in the para-mesangial area and in the glomerular basement membrane. The patient underwent right radical nephrectomy. Histologic examination of the resected specimen revealed renal cell carcinoma. Postoperatively, he developed rapidly progressive renal failure and the renal function could not be recovered. Using the indirect immunofluorescence technique, we could not confirm the presence of a serum anti-glomerular basement membrane antibody, although the examination could not be carried out until the initiation of hemodialysis therapy. Some cases of glomerulopathies associated with renal cell carcinoma were previously reported, but the case of crescentic glomerulonephritis was very rare.
