3 Fig 2 Macroscopic findings of the resected right upper lobe. The cut surface of the right upper lobe shows a distinct grayish-white portion and a black portion of the tumor (top). Topographic presentation shows two different components (bottom). (Ad. = adenocarcinoma.)

(b) The large cell carcinoma has a clear cell and a clumped nucleus. (c) Adenocarcinoma is shown as a well-differentiated and papillary type.
