An incidental finding of chronic lymphocytic leukaemia in a patient with pulmonary tuberculosis

Abstract

In this case report, we described a 48-year-old human immunodeficiency virus-negative man with pulmonary tuberculosis (TB) who had an incidental finding of concurrent chronic lymphocytic leukaemia. We highlighted the importance of considering other differential diagnoses when patients present with TB or haematological malignancies. We also discussed the difficulties in diagnosis when both of these conditions co-exist and how this affected treatment and management.
