Figure 1

Frequencies of IRF4 FISH abnormalities and IRF4 protein expression, stratified by T-cell lymphoproliferative disorder subtype. (a) IRF4 translocations were limited to cutaneous anaplastic large cell lymphomas (20%) and a single case of lymphomatoid papulosis (3%). (b, c) Other IRF4 FISH abnormalities and IRF4 protein expression were widely distributed over T-cell lymphoproliferative disorder subtypes.
