摘　　要：BACKGROUND Uterine myoma is the most common benign tumor among women and is often accompanied by anemia.Here,we report the case of a patient with a very large leiomyoma but with a hemoglobin level as high as 197 g/L.After undergoing hysterectomy,all her hematological parameters returned to normal.Immunohistochemical staining of her myoma for erythropoietin showed strong positivity,which suggested that erythropoietin may be the cause of her erythrocytosis.A multidisciplinary team played a significant role in treating the disease.CASE SUMMARY A 47-year-old woman visited our department complaining that her abdomen had been continuously growing for the past 2 years.After careful examinations,she was suspected of having a very large leiomyoma.She was also diagnosed with erythrocytosis because her RBC count was 6.49×10^(12)/L,hemoglobin was 197 g/L.Following a multidisciplinary team consultation,bilateral ureteral stents were placed,and 800 m L blood was removed by phlebotomy.The patient then underwent hysterectomy and bilateral salpingectomy.She recovered well from the operation,and her hemoglobin level decreased sharply following the surgery.Low-molecular-weight heparin was administered daily to prevent postoperative thrombosis.She was discharged from the hospital on the fourth postoperative day.Two months later,all her hematological parameters returned to normal.Pathological analysis of the myoma revealed that it was a benign leiomyoma,with partial hyalinization,and strong positivity for erythropoietin in immunohistochemical staining suggested that erythropoietin may be responsible for the erythrocytosis.CONCLUSION Erythropoietin ectopically produced from the myoma was responsible for the erythrocytosis in this patient.A multidisciplinary team is strongly recommended.
