Introduction: Pediatric adrenocortical tumors (pACT), comprising highly malignant pediatric adrenocortical carcinomas (pACCs) and less aggressive adenomas (pACAs), present a rare yet clinically significant challenge. pACTs often pose a diagnostic and therapeutic dilemma due to their elusive differentiation and resistance to therapy. Originating from the adrenal cortex, pACTs are functional and, thus, characterized by a unique urinary steroid metabolome. This s...
