title: [A case of renal cell carcinoma of horseshoe kidney that produced AFP and caused hypercalcemia].
abstract: A very rare case of renal cell carcinoma of the horseshoe kidney that produced AFP and caused hypercalcemia is reported. The relationship between this renal cell carcinoma and hypercalcemia was obvious, but the mechanism of hypercalcemia was not revealed. The presence of AFP in cancer cells was demonstrated using the "ABC" method.
