Figure 2

An 8.0-cm MEN-1 pancreatic neuroendocrine tumor displaying biphasic morphology and heterogeneous immunolabeling for DAXX. The more typical pancreatic neuroendocrine morphology is seen on the left; a second morphologic pattern with prominent nucleoli and abundant cytoplasm is seen on the right. Both areas demonstrated the alternative lenghthening of the telomeres phenotype. H&E (a), DAXX (b). All images were taken at × 400 magnification.
