title: [Characterization of ovarian adrenal rest tumors in children and adolescent females with congenital adrenal hyperplasia due to 21-hydroxylase deficiency].
abstract: OBJECTIVE
  To summarize the characterization of ovarian adrenal rest tumors (OART) in children and adolescent females with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD).
  
  
  METHODS
  We have diagnosed 4 cases of CAH 21-OHD with OART in the recent 5 years in pediatric endocrinology unit of the first affiliated hospital of Sun Yat-Sen University. Clinical characterizations were summarized, including symptoms, growth patterns and bone age advancements, serum steroid concentrations, imaging results and the follow-up data.
  
  
  RESULTS
  The 4 cases of OART accounted for 2.5 % of the CAH 21-OHD girls, which was much lower than the detection rate, 29.5%, of testicular ART in our patient group during the same period. The 4 cases included 3 salt wasters and 1 with simple virilizm. OART were diagnosed at the age of 8.9 years, 15.8 years, 21.4 years and 9.3 years, respectively. Before the diagnosis of OART, their daily hydrocortisone doses reached 16 mg/(m(2)·d)to 24 mg/(m(2)·d). The patients presented with deteriorated acne, deepened voice, amenorrhea (2 cases), accelerated growth and advanced bone age, ΔBA/ΔCA reached 1.2(during GnRHa treatment)and 2.0. Their serum adrenal steroids increased significantly and hyperplasia of adrenal glands were found in all patients. The diagnosis could be confirmed before the operation in only 1 case. The diagnosis could not be made until the planned sub-total adrenalectomy in the other 3 cases. The follow-up periods of OART were 4.8, 4.7, 3.8 and 2.7 years, respectively. Removal of OART resulted in symptoms relief at least partialy and lowered daily hydrocortisone doses, 14 to 19 mg/(m(2)·d).
  
  
  CONCLUSIONS
  The detection rate of OART was much lower than testicular ART. Before the diagnosis of OART, the patients presented with deteriorated virilescence, accelerated growth and advanced bone age, elevated serum adrenal steroids and hyperplasia of adrenal glands. Removal of the OART resulted in symptoms relief at least partialy.
