Two cpACs had faint stromal staining for VEGF and PDGFRα whereas; PDGFRβ had distinct strong stromal tumor staining in 92% (11/12) with faint positive cytoplasmic staining and rare membranous staining of the neoplastic cells in 75% (9/12) (Figure 2 and Table 2). This evidence concerns the gene VEGFA and neoplasm.
