Pathology of left thoracic mass: (a) Hematoxylin and eosin staining slide at *400 magnification. The cells of thoracic mass showed the structure of spleen that was adjacent to the lung tissue. (b) immumohistochemical stain at *400 magnification. Cells of masses were CK(−)、CD3(T cell+)、CD20(B cell+)、TTF-1(−)、Syn(−)、Ki-67(+,5%)、CD34(sinusoid+)、CD8(sinusoid+)、CD1a(−)、S-100(−)、CD68(sinusoid+)
