一名有糖尿病(DM)和肥胖病史的47岁女性入院进行血糖控制。根据日本高血压学会(JSH)指南的标准,基于高水平的醛固酮/肾素比值和直立呋塞米负荷试验结果,检测到患者患有高血压(HT),并诊断为原发性醛固酮增多症(PA)。电脑断层显示左肾肿瘤和肾上腺皮质腺瘤。她接受了左肾切除术和肾上腺切除术。病理结果为透明细胞肾细胞癌(RCC)和非功能性肾上腺皮质腺瘤。她的非肿瘤性肾上腺组织组织学检查显示CYP 11B 2阳性多发性肾上腺皮质微结节(MN)和伴随的肾小球异常增生。因此,MN被认为是该患者PA的原因。术后,HT改善,根据JSH指南,术后12个月的直立呋塞米负荷试验结果不符合PA标准。然而,促肾上腺皮质激素刺激试验呈阳性;考虑到右肾上腺可能轻微醛固酮过量,开始给予螺内酯。在此,我们报告一个罕见的情况下,肾细胞癌与PA组织学相关的MN。
A 47‐year‐old woman with a history of diabetes mellitus (DM) and obesity was admitted to our hospital for glucose control. She was detected to have hypertension (HT) and diagnosed with primary aldosteronism (PA) based on the high level of aldosterone to renin ratio and the results of the upright furosemide‐loading test according to the criteria of the Japanese Society of Hypertension (JSH) guidelines. Computed tomography revealed left renal tumor and adrenocortical adenoma. She underwent left nephrectomy and adrenalectomy. The pathological findings were clear‐cell renal cell carcinoma (RCC) and nonfunctional adrenocortical adenoma. Her nonneoplastic adrenal tissue histologically revealed CYP11B2‐positive multiple adrenocortical micronodules (MNs) and concomitant paradoxical hyperplasia of the zona glomerulosa. Therefore, MNs were thought to be responsible for PA in this patient. After surgery, HT was improved, and the result of upright furosemide‐loading test after 12 months of surgery did not fulfill the criteria of PA according to the JSH guidelines. However, the adrenocorticotrophic hormone stimulation test was positive; considering the possibility of slight aldosterone overproduction from the right adrenal gland, the administration of spironolactone was started. Herein, we report a rare case of RCC in conjunction with PA histologically associated with MNs.
