CASO 16-3294

Case 3

Summary• Morphology:

– Diffuse pattern. – Small mature cells with round nuclei, clumped chromatin.– Vessels with neoplastic emboli consisting of medium-sized cells,

hyperchromatic nuclei and clumped chromatin .

• Immunohistochemistry:– Small to medium sizes cells: CD20+, CD23+, BCL2+, CCND1-,

BCL6-, Ki67 15%– Neoplastic emboli: CD3+, CD56+, CD8+, CD7+, CD30+, BCL2+,

CD4-, CD2-, Ki67 90%.• CISH:

– EBER positive

Summary

• TCR gene rearrangements:– A clonal product is evident in the analysis in the TCR beta locus– Additionally clonal product is observed in the analysis of TCR

gamma locus– The monoclonal peak appears in the middle of a strong

polyclonal component– Conclusion: positive for detecting a TCR gene rearrangement
