Objective To investigate the clinical and pathological characteristics of CD20 positive vascular immunoblastic T-cell lymphoma (AITL). Method: The clinical pathological characteristics and prognosis of one case of CD20 positive AITL diagnosed and treated at the First People's Hospital of Foshan City, Guangdong Province, and four cases reported in the literature were analyzed. Among the 5 AITL patients, there were 4 males and 1 female, with an average age of 61 years. Three cases were negative for CD20 at initial diagnosis and only expressed CD20 at recurrence. Three cases were misdiagnosed, of which two were misdiagnosed as non-specific peripheral T-cell lymphoma and one was misdiagnosed as diffuse large B-cell lymphoma. 3 cases received rituximab treatment, 2 cases were effective, and 1 case was unable to evaluate the efficacy. Conclusion: The clinical pathological characteristics of CD20 positive AITL patients are easily confused with B-cell lymphoma, and pathological morphology, immunohistochemistry, and TCR gene rearrangement testing can reduce misdiagnosis. It is not yet clear whether rituximab is beneficial, and effective treatment plans should be actively sought to improve the cure rate and patient prognosis.
