2 Fig 1 (A) A magnetic resonance image shows that the tumor has invaded the nasopharyngeal wall (yellow arrow). (B, C) Hematoxylin and eosin staining of a biopsy specimen shows a nonkeratinizing carcinoma with lymphocyte infiltration (B, ×80; C, ×200). (D) In situ hybridization shows diffuse positive staining of Epstein-Barr virus mRNA (×200).

3 Fig 2 (A) Chest computed tomography before treatment for nasopharyngeal cancer revealed two small nodules in the right lower lobe of the lung (red arrows). (B–F) Six nodules appeared within 1 year after treatment initiation (red arrows). All the nodules were present in the right lower lobe.

4 Fig 3 (A, B) Hematoxylin and eosin staining of a resected lung nodule shows pulmonary metastasis of the nasopharyngeal cancer (A, ×80; B, ×200). (C) In situ hybridization shows diffuse positive staining of Epstein-Barr virus mRNA in all resected lung nodules (×200). (D) An intraalveolar floating cancer cell cluster is separate from the primary tumor (×200).
