Endogenous CS is classified into 2 main categories: ACTH-dependent and ACTH-independent disease. (invisionzone.com)
In ACTH-dependent disease, the source of ACTH can further be subdivided into either the pituitary gland or an ectopic source [ 2 ]. (invisionzone.com)
Hence, the measurement of such ACTH precursors warrants further evaluation, especially in the context of ACTH-dependent hypercortisolism. (uanl.mx)
