The tumour cells in areas with pleomorphic polygonal epithelioid type cells spread in sheets without ductal morphology showed diffuse strong immunopositivity for EMA,p63 and p40 but immunonegative for Keratin 7, AR, GCDFP-15, Her2Neu, BerEp4, S100, SMA and calponin (Fig. 2a–d). This evidence concerns the gene SMN1 and neoplasm.
