頭痛を主訴とした17歳女に発症した傍糸球体細胞腫例.本症は,これまでに40数例が報告されているに過ぎない比較的稀な疾患であるWe report a case of juxtaglomerular cell tumor. A 17-year-old female complained of headache with severe hypertension, hypokalemia, and elevated level of plasma renin activity. Computerized tomographic (CT) scan revealed a slightly enhanced tumor at middle pole of right kidney. Angiography showed a hypovascular tumor. A renin secreting tumor of the right kidney was diagnosed and right nephrectomy was performed. The pathological findings showed a juxtaglomerular cell tumor. Postoperatively, prompt normalization of blood pressure and decrease of plasma renin activity level were found. This case was incorporated into a review of the 43 cases previously published and we discussed the clinical characteristics of juxtaglomerular cell tumor in this report.
