Demonstration of co-expression of VEGF and Flt-1 in neoplastic myelomonocytic leukemia cells in a patient with CMML.
(upper left) Hematoxylin and eosin staining. (upper right) IHC for VEGF demonstrating strong protein expression. (lower left) Same patient demonstrating co-expression of the Flt-1/VEGFR-1 receptor. (lower right) Rare KDR/VEGFR-2 positive cells were observed (1000 × magnification).
