(a) Clinically localized prostate cancer Gleason grade 6 (3 + 3) with Paneth cell–like neuroendocrine differentiation (upper inset); BRAF-EPB41 gene fusion was identified in this case by sequencing and was validated by fluorescence in situ hybridization(lower inset showing breakapart of the BRAF gene); (b) diagrammatic representation of novel BRAF rearrangement illustrating preserved kinase domain.
