Plasmablastic lymphoma (PBL) is an aggressive lymphoma with limited treatment strategies. Tuberculosis (TB) infection poses a high risk for patients with hematologic malignancies, especially those treated with immune agents but were never reported post-daratumumab treatment. Herein, we reported a TB infection in a 57-year-old male diagnosed with HIV-negative PBL receiving daratumumab-based treatment, who showed atypical lung infection and yielded Mycobacterium tuberculosis and cytomegalovirus (CMV) in the bronchoalveolar lavage fluid. Anti-TB therapy was administered, and the following daratumumab treatment was complete with good tolerance. In this case, we demonstrated that TB infection might occur after daratumumab therapy, and adequate attention should be paid to atypical symptoms.
