A 68-year-old man with interstitial pulmonary fibrosis underwent bilateral lung transplantation. Histopathologic examination of hilar lymph nodes in the explanted lungs showed effacement of normal nodal architecture by the proliferation of small lymphocytes, consistent with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL). Unexpectedly discovered malignancies at the time of lung transplantation is uncommon, especially in the lymph nodes. The clinical management was challenging because of attempts to balance treatment of CLL and immunosuppressive treatment to prevent graft rejection. Here, we report a case of incidentally detected CLL in hilar lymph nodes with explanted lungs and review the relevant literature.
