EBV-Negative Monomorphic B-Cell Posttransplant Lymphoproliferative Disorder with Marked Morphologic Pleomorphism and Pathogenic Mutations in ASXL1, BCOR, CDKN2A, NF1, and TP53

<div>FISH analysis for TP53 deletion. FISH studies performed on formalin-fixed paraffin-embedded sections of the small bowel tumor using TP53/NF1 probe revealed (a) deletion of TP53 in 14/100 cells and (b) monosomy of chromosome 17 in 20/100 cells. (c) Normal cell.</div>
