The T cells have variable expression of CD3, bright CD45, CD1a, cCD3, and a subset of double CD4/CD8 positive group, and uniformly positivity on CD5 and CD7(Fig. 1, Fig. 2, Fig. 3, Fig. 4). The immunophenotypic features were favorable for Type B2 thymoma with imaging suggestive of a Masaoka-Koga
TdT coexprression in T cells. Consistent with thymic tissue.

The T cells have variable expression of CD3, bright CD45, CD1a, cCD3, and a subset of double CD4/CD8 positive group, and uniformly positivity on CD5 and CD7(Fig. 1, Fig. 2, Fig. 3, Fig. 4). The immunophenotypic features were favorable for Type B2 thymoma with imaging suggestive of a Masaoka-Koga
MRI of the chest with red arrows pointing to the thymoma. (A) Sagittal view, (B) Coronal view. (C) Inferior transverse view. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article).
