However, its identification criteria, form of reporting, and subsequent effects on the clinical course of this disease remain controversial and not fully defined. Here, we report and discuss a case of breast invasive ductal adenocarcinoma with substantial intratumoral heterogeneity, discrepancy between Her2/neu immunostaining and in situ hybridization, and disparity between estrogen receptor status before and after neoadjuvant therapy.}, keywords = {Breast,Estrogen receptor,ErbB-2,Genetic heterogeneity,Personalized Medicine}, url = {https://mejc.sums.ac.ir/article_42138.html}, eprint = {https://mejc.sums.ac.ir/article_42138_45a8895ef94736efe8147ee50365c0a2.pdf} }
