The limited knowledge about male MGTs prompted the application of many different IHC markers, including hormone receptors: oestrogen receptor alpha, progesterone receptor, such cytokeratins as 5/6, 7, 8/18, 15 and proteins p53, p63, calponin, and GATA3 to gain new knowledge of the tumour behaviour (Table 1). This evidence concerns the gene PGR and neoplasm.
