Figure 5.
PCR studies of PTCL-NOS, follicular variant, containing HRS-like cells (Case 5). TRG PCR identifies two identical peaks, consistent with a clonal rearrangement in all three specimens tested: soft tissue 2011 (A), inguinal lymph nodes 2006 (B) and 2004 (C). This confirms that the same disease process is present in different sites and at different time points at molecular level. Color code of interrogated joining segments of TCR locus: black – J1/2; green – JP1/2 and blue – JP.
