Objective To explore the clinical characteristics,diagnosis and treatment of benign liver tissue ectopia in adrenal tumor,so as to improve the understanding of this disease.Methods We reported the data of a rare patient with ectopic liver tissue to adrenal gland admitted in the Department of Urology,Liaocheng Second Hospital Affiliated to Shandong First Medical University and discussed it in conjunction with literature.Results The patient was a 32-year-old male who sought medical attention for more than half a year due to elevated blood pressure and detection of a tumor in the right adrenal gland.Ultrasound and CT examinations showed a tumor in the right adrenal gland,suggesting myeloid lipoma.Laparoscopic right adrenalectomy was performed,and the postoperative pathology showed benign liver tissue ectopia in adrenal tumor,hepatocyte proliferation,steatosis,and slight lymphocyte infiltration.Immunohistochemistry suggested Hep-1(+).During the follow-up of 12 months,the patient recovered well with no complications.Imaging examinations showed no signs of recurrence.Conclusion Benign liver tissue ectopia in adrenal tumor is very rare and is difficult to diagnose preoperatively.Diagnosis is mainly based on pathology,and surgical resection is usually chosen.
