A case of pulmonary @entity706 is reported. A 65-year-old @entity1 had no complaint. But chest roentgenography and CT revealed an infiltrating shadow with marked airbronchogram in the left S3. TBLB revealed marked @entity2617 of the bronchial wall. Because the shadow had gradually enlarged, @entity5 was suspected and lobectomy was performed. The resected specimen showed a 60 @entity71948 30 mm greyish-yellow, @entity5 with intrapulmonary @entity3 . Microscopically, well-differentiated small @entity5 cells severely infiltrated the @entity358 , pleura and bronchial cartilage. There was no lymph node @entity3 or extrapulmonary involvement. Immunohistochemical study proved the monoclonality of the K chain. She was treated with chemotherapy postoperatively.
