Objective:To explore the clinical features and prognosis of CD20-positive extranodal NK/T cell lymphoma. Methods:To analyze the clinical characteristics and prognosis of 11 ENKTL patients admitted to this hospital. Results:Among the 11 patients, 6 cases with elevated LDH, 6 cases of anemia, and 8 cases with Ki-67≥50%. Two cases survived; 1 case lost contact; 8 cases died, and the average survival time of 8 cases was 22.5 months. Conclusion:The diagnosis of CD20 positive ENKTL is difficult, which requires a combination pathomorphology, immunohistochemistry, EBER and gene rearrangement detection and improve the understanding of the disease.Early diagnosis and active treatment is important.
