目的:探讨肾上腺嗜酸细胞腺瘤的临床及病理特点。方法:回顾性分析1例肾上腺嗜酸细胞腺瘤患者的临床资料:男,54岁,体检时B超发现左肾上腺区肿物,CT检查发现6.0cm×5.3cm肾上腺区肿物。肾素、醛固酮、儿茶酚胺实验值均正常。行肾上腺肿物切除术。结果:术中发现肿物体积较大,包膜完整光滑,与周围组织无粘连,肿物表面血管较为丰富,术中触碰肿物,血压无波动,遂完整切除肿物。术后病理检查显示肿瘤细胞嗜酸性,内部充满颗粒,诊断为肾上腺嗜酸细胞腺瘤。随访6个月无复发。结论:肾上腺嗜酸细胞腺瘤是一种具有潜在恶性的良性肿瘤,可手术切除,但术后需密切随访。 Objective: To investigate the clinical and pathological characteristics of adrenal eosinophilic adenoma. Methods: A retrospective analysis of 1 patient with adrenal eosinophilic adenoma clinical data: male, 54 years old, physical examination, the left adrenal area was found by B ultrasound, CT examination found 6.0cm × 5.3cm adrenal area tumor. Renin, aldosterone, catecholamines were normal experimental values. Adrenal removal. Results: During the operation, the volume of the tumor was large, the capsule was smooth and complete, and there was no adhesion with the surrounding tissues. The blood vessels on the surface of the tumor were more abundant. The tumor touched the tumor during operation, and the blood pressure did not fluctuate. Postoperative pathological examination showed eosinophilic tumor cells, the internal full of particles, the diagnosis of adrenal eosinophilic adenoma. Follow-up 6 months without recurrence. Conclusion: Adrenal acidophilic adenoma is a potentially malignant benign tumor that can be surgically removed but closely followed up.
