In prostatic lesions, the role of mast cell infiltration varies with the type of the lesion. They mediate the biological consequences such as mitogenesis, extracellular matrix degradation and spread of tumors by recruiting various growth factors and cytokines. In BPH, there is significant increase in mast cell count when compared to normal prostate. Mast cells help in progression of nodular hyperplasia by release of their degranulation products and mediators. In Ca-Prostate, the pro-tumor effect of mast cells is due to secretion of histamine and growth factors such as VEGF, PDGF, SCF, Nerve growth factor and metalloprotease, that contribute to majority of proteolytic components necessary for tumor invasiveness. The major pro-tumor effect of mast cells is the angiogenic activity brought about mainly by secreting VEGF which is reflected by increased vascularity in prostate cancer.
