Figure 5
Immunohistochemical staining of the pulmonary metastatic lesion showed strong and diffuse positivity for vimentin, α1-antitrypsin, and CD10 (a–c), patchy positivity for desmin, CD56, and BCL2 (d–f), rare staining for CD68 (g), and negative for myogenin and AE1/AE3 (h and i). The entrapped bronchiolar epithelium was highlighted by AE1/AE3 (i) (arrow) (immunoperoxidase; original magnification: (c, d, g, and i) ×100; (a, b, e, f, and h) ×200).
