title: [A Case Report : Spontaneous Rupture of Chromophobe Renal Cell Carcinoma].
abstract: A 31-year-old man presented with sudden right flank pain. We found a right renal tumor with a perirenal hematoma on enhanced abdominal computed tomography (CT), which suggested spontaneous rupture of the renal tumor. The tumor was located at the upper pole of the right kidney, and was not enhanced. Magnetic resonance imaging (MRI) showed slightly enhanced renal tumor, and positron emission tomography (PET) showed a hot spot in the renal mass. His anemia was getting worse, and we assumed that the renal mass was malignant. Therefore, we performed a right nephrectomy with a transperitoneal approach. On pathological examination, the tumor was found to be chromophobe renal cell carcinoma. The tumor contained a significant amount of necrotic tissue and a hematoma.
