Figure 4. Cytogenic FISH with detection of PDGFB gene rearrangement (A-D).
Immunofluorescent areas on cytogenic FISH indicate positive PDGFB gene rearrangement expression. A-D are four different slices of the specimen revealing positive PDGFB expression.
FISH: Fluorescence in situ hybridization; PDGFB: Platelet-derived growth factor subunit B
