title: [Congenital adrenal hyperplasia complicated by testicular adrenal rest tumors: one-case clinical analysis].
abstract: OBJECTIVE
  To investigate the early diagnosis and treatment of congenital adrenal hyperplasia (CAH) complicated by testicular adrenal rest tumors (TART).
  
  
  METHODS
  We retrospectively analyzed the clinical data of 1 case of late-onset CAH complicated by TART diagnosed and treated in Xiamen Women and Children Health Care Hospital.
  
  
  RESULTS
  The patient was a 15 years old boy, short statured and dark skinned, with skin pigmentation in the gum and external genital, secondary sex characteristics of the adult and irregular tubercles palpable in the bilateral testes. Laboratory examinations showed obviously increased levels of ACTH, 17-KS, DHEA-S and progesterone and evidently decreased levels of FSH, LH and CO. The low-dose dexamethasone suppression test reduced ACTH and DHEA-S to normal. Imaging examinations revealed soft tissue density in the bilateral adrenal glands, especially on the right, and irregularly increased volume of the bilateral testes, particularly on the left, with heterogeneous signals and septas and surrounded by the fluid signals. Histopathological examinations showed the eosinophilic cytoplasm to be polygon- or round-shaped, interstitium-like cells arranged in line, and lipopigment in the endochylema. Immunohistochemical results were negative for testicular interstitial cell tumor. The clinical signs of the patient were improved after 3 months of dexamethasone treatment, the hyperplastic nodules in the left testis decreased obviously and those in the right testis disappeared after 6 months, and the hyperplastic nodules in the adrenal glands vanished after 9 months.
  
  
  CONCLUSIONS
  Based on the clinical manifestations and the results of auxiliary examinations, this case was diagnosed as late-onset CAH complicated by TART, which was attributed to the continued surge of ACTH induced by corticoadrenal insufficiency. Sufficient dexamethasone treatment could make the TART decrease or disappear and the CAH vanish; it could also improve the clinical symptoms and bring the laboratory results to normal.
