ABSTRACT
In Korea chronic lymphocytic leukemia(CLL) is a rare diesase with evidence immunologic incompetence. The immunodeficiency of patients with CLL could place them at increased risk of new cancers. The incidence of secondary malignancy, including lung cancer has increased in patients with CLL and this should be also considered in the differential diagnosis of a new pulmonary infiltrate appearing in patients with known CLL. A-73-year old male patient with CLL was admitted to our hospital because of dyspnea. Chest X-ray showed multiple scattered small nodules in both lung fields and alveolar consolidation mass at right lower lung.
Histopathological examination of the bronchoscopic biopsy specimen demonstrated that he had a moderatly differentiated adenacarcinoma of lung. Since we experienced a case of metachronous adenocarcinoma of lung in patient with known CLL, we report this with a review of literatures.
