Pediatric Adrenocortical Tumors: Clinicopathological Features—An Update

摘要

Pediatric adrenocortical tumors (ACTs) are rare in children. Most tumors are hormonally active with overproduction of androgens and glucocorticoids, and less frequently mineralocorticoids and estrogens. Patients usually present with clinical signs of virilization or Cushing syndrome, while only a minority of ACTs are incidentally discovered. Unfortunately, the clinical behavior of pediatric ACTs is often unpredictable, and the distinction between benign and malignant tumors is still challenging. The present review deals with the main clinical and laboratory features which can help to diagnose pediatric ACTs, with special emphasis on the pathological criteria useful to stratify patients into three different prognostic categories: (1) patients with benign tumors; (2) patients with malignant tumors; and (3) patients with borderline tumors (tumors with indeterminate malignancy). In this regard, general guidelines and histological illustrations are provided to offer a practical approach for a correct identification of morphological predictors of clinical outcome.
