[A Case of Spontaneous Rupture of Chromophobe Renal Cell Carcinoma].

Spontaneous rupture of renal cell carcinoma (RCC) occurs in 0.3-0.6% of all RCC cases. A 57-yearold woman presented to the emergency department with a chief complaint of hematuria and lower back pein. Ruptures of a kidney tumor and a kidney capsular hematoma were detected using computed tomography. The patient underwent radical right nephrectomy 22 days post admission, and the pathological diagnosis was chromophobe RCC (ChRCC). To our knowledge, this is the third reported case of ChRCC. The previous two cases did not exhibit postoperative recurrence, and yielded good prognoses. However, in our case, liver metastasis occurred 1 month postoperatively, and the prognosis was poor.
