Corticotroph tumours, comprising around 15% of pituitary tumours, express ACTH and other peptides originating from TPIT-lineage adenohypophyseal cells. Their tumorigenesis involves a complex interplay of genetic and epigenetic factors and hormonal and growth factor stimulation. Silent corticotroph tumours (SCT) share immunopositivity for ACTH and TPIT with functioning corticotroph tumours (FCT) but do not exhibit evidence of hypercortisolism. Despite their aggressive growth an...
