Objective: Large response of steroids precursors, including 17-hydroxyprogesterone and 11-deoxycortisol, to ACTH has been described in adrenocortical tumors, suggesting the existence of intra-tumoral enzymatic deficiencies. This study aimed to compare steroidogenic enzymes activity in unilateral and bilateral benign tumors using serum steroid profiling in HPLC-MS/MS in basal state and after ACTH 1-24 stimulation.Design and Methods: A serum profile of sev...
