Spontaneous rupture of renal cell carcinoma: A case report

A 29-year-old woman was transported to the Emergency Clinic of our institution because of increasing right abdominal pain. CT scan revealed right perirenal hemorrhage due to a renal tumor and the inferior vena cava (IVC) was markedly compressed by the huge hematoma. No sign of fat tissue was found in tumor lesion and therefore the clinical diagnosis was spontaneous rupture of renal cell carcinoma. Immediate right radical nephrectomy was performed. Histopathological study revealed clear cell renal cell carcinoma. Blood hemoglobin was reduced to 4.8 g/dl at the third day postoperatively, after which it recovered to the normal level without blood transfusion. No evidence of recurrence has been observed for 16 months since the operation.
