Functional adrenal cortical tumors in pediatric patients: A clinicopathologic and immunohistochemical study of a long term follow-up series

Abstract

Our data show that small tumors (less than 100 g) are associated with good outcome; the two patients with the poorest prognosis had Cushing's syndrome and large tumors (more than 100 g). Histologic features are not adequate predictors of outcome and PCNA may be useful in tumors of patients with Cushing's syndrome, but this parameter should not be used alone. Two patients had virilization syndrome, large tumors (185 g and 800 g, respectively), and good outcomes, which contradicts with the concept that these tumors are usually associated with poor prognosis.
