Now you see me, now you don't: Isolated central nervous system recurrence of CD19-negative diffuse large B-cell lymphoma following CD19-directed CAR T-cell treatment

Cytopathology. 2022 Nov;33(6):757-759. doi: 10.1111/cyt.13160. Epub 2022 Jul 1.

Abstract

The authors discuss a case of CD19-negative diffuse large B-cell lymphoma with central nervous system relapse following CD19-directed CAR T-cell treatment. Absence of CD19 expression by the tumour cells presented a challenge for flow cytometry evaluation.

Keywords: CAR T-cell Therapy; CNS Relapse; Cytopathology; Diffuse Large B-cell Lymphoma.
