A 17-year-old man was admitted to our hospital with a chief complaint of right flank pain. Both computed tomography and magnetic resonance imaging demonstrated a tumor hemorrhage in a mass located at the upper pole of the right kidney. He had a high blood pressure of 220/100 mmHg associated with high serum renin activity (36.2 ng/ml/hr). Partial nephrectomy was performed and histopathological examination revealed a juxtaglomerular cell tumor. Postoperatively, his blood pressure was markedly improved and the serum renin activity immediately fell into the normal range. Previously, 32 cases of juxtaglomerular cell tumor have been reported in the Japanese literature, and to our knowledge, this is the first case was found with a tumor hemorrhage. |
