CK/LMP1 double positive TECs were never detected in MG and non-MG thymomas (Figure 5), whereas CK/LMP2A double positive cells were only occasionally found in MG-associated thymomas (Figure 5A), whereas rare CK/LMP2A double positive TECs were found in one of the three non-MG thymomas, found positive for EBV DNA and EBER1 [MG (-) T14] (Table 2) (Figure 5B). This evidence concerns the gene PDLIM7 and thymoma.
