The long-term sequelae on the growth pattern in successfully resected virilizing adrenal tumors (ACT) have not been clearly defined. We report on 10 years follow-up of a boy with virilizing ACT until the attainment of final height. This is the first clinical description in a boy with a marked advancement of bone age, indicating that despite advanced physical and skeletal maturity the prognosis on growth is good, provided that regression of virilization is obtained.
