title: [Poor outcome due to spontaneous rupture of renal cell carcinoma : a case report].
abstract: A 54-year-old man experienced sudden onset of severe pain in his left lower back. Because the pain persisted for two days, he visited our hospital. Abdominal computed tomography revealed a hematoma around his left kidney, which was diagnosed as spontaneous rupture of a renal tumor. He was immediately admitted and was scheduled to undergo elective surgery. However, because his hemoglobin level decreased suddenly on Day 9 and rebleeding from the renal tumor was suspected, we chose to perform left radical nephrectomy following emergency transcatheter arterial embolization of his left renal artery. The resected specimen was a solid brownish-red mass surrounded by hematoma, and the histopathological findings revealed that it was a renal clear cell carcinoma (G3＞G2, INFα, pT1b, and pV0). On Day 51, he was found to have a local recurrence of carcinoma, and died five months after surgery. Spontaneous rupture of renal cell carcinoma is relatively rare : this is the 104th report on surgery for this carcinoma in Japan.
