Crescentic Glomerulonephritis in Association With Renal Cell Carcinoma: A Case Report

Clear renal cell carcinoma (RCC) is the most common primary renal tumor originating within the renal cortex. It is responsible for 75% to 85% of all primary renal neoplasms. Multiple risk factors are associated with the development of RCC, the most common being smoking. On some occasions, RCC has been linked to some autoimmune conditions, but data is limited. Especially, its association with glomerulonephritis (GN) is rare in literature and not fully understood. In this case report, we discuss a presentation of RCC associated with crescentic GN.
