A 53-year-old man with a 1-year history of chronic lymphocytic leukaemia (CLL) presented with a left bicep mass. Biopsy and staging workup revealed Richter’s transformation (RT) Ann Arbor stage 1E diffuse large B-cell lymphoma in the bicep. The patient was treated with combination chemotherapy with cyclophosphamide, doxorubicin, Vincristine and prednisone followed by site radiation and did well thereafter. His CLL progressed and required treatment on two more occasions 11 and 18 years after his initial diagnosis with fludarabine, Cytoxan and Rituxan and then with bendamustine and rituximab. 23 years after initial presentation, he developed diffuse lymphadenopathy and B-symptoms. A biopsy of an enlarged cervical lymph node demonstrated only CLL for which he was started on ibrutinib. Treatment was shortly discontinued thereafter due to intolerance and worsening symptoms. A second biopsy was performed which revealed concurrent CLL and Hodgkin’s lymphoma representing a second and histologically distinct RT.
