Renal carcinoma with staghorn calculus, perinephric abscess, and xanthogranulomatous pyelonephritis in same kidney. Subcutaneous abscess of thigh as initial presentation.

A case is reported of the simultaneous occurrence of renal carcinoma with staghorn calculus, perinephric abscess, and xanthogranulomatous pyelonephritis in the same kidney, with subcutaneous abscess of the thigh as the initial presentation. The coexistence of these diseases in the same kidney would seem to be important since they are frequently confused with each other.
