Rituximab-based combination therapy and Bruton's tyrosine kinase (<i>BTK</i>) inhibitors have greatly improved the prognosis of WM. Despite the high response rate and good tolerance of <i>BTK</i> inhibitors in treatment of WM, a proportion of patients still experience disease progression. <b>Case presentation:</b> We report a 55-year-old man with relapsed WM. The patient achieved partial remission after six courses of CHOP chemotherapy and multiple plasma exchanges in initial treatment. He was admitted to the hospital with abdominal distension, and was diagnosed with relapsed WM and subsequently started on zanubrutinib.
