2 FIGURE 1 A, Chest computed tomography with a 51-mm irregular mass in the right upper lobe (arrow). B, Cut surface of the lobectomy specimen showing a lobulating grayish and yellow-tan solid mass. C, Hematoxylin and eosin staining shows adenocarcinoma with a solid pattern (×200). D, ALK immunohistochemical staining shows diffuse cytoplasmic pattern (×200). E and F, FISH assay of the ALK genomic rearrangement with split 5’- and 3’-probe signals (red and green arrows) with occasionally increased ALK copy number.

3 FIGURE 2 A, Schematic structure of the genomic DNA sequence (upper) and DNA sequence chromatograms (lower) showing fusion points for genomic rearrangement and TPR-ALK fusion transcript cDNA. B, Functional domain structures of TPR, ALK, and TPR-ALK proteins. TPR, translocated promoter region; ALK, anaplastic lymphoma kinase; JM, juxtamembrane.
