case_images: Representative IHC results of Case 1 (Polymorphic PTLD) are shown in Fig. 1. The neoplastic cells were positive for CD2, CD3, CD7, CD8, and CD43 (Fig. 1A-E), partially positive for CD79a, Granzyme B, and TIA-1 (Fig. 1F-H), and negative for CD5, CD20, and CD30. Scattered lymphocytes were positive for EREB (Fig. 1I). The Ki-67 of these cells was approximately 60% (Fig. 1J).
