title: Testicular adrenal rest tumors in congenital adrenal hyperplasia: a case report and literature overview.
abstract: OBJECTIVE
  In this paper, the etiology, differential diagnosis, and therapy of testicular adrenal rest tumors (TARTs) is presented based on a patient presentation and an overview of the most recent literature concerning this subject.
  
  
  METHODS
  Retrospective analysis of the clinical and biochemical data of an 18-year-old male patient diagnosed at the age of 2 weeks with the classic salt-wasting form of congenital adrenal hyperplasia that has been monitored in the pediatric and adolescent outpatient department since the age of 4 years.
  
  
  RESULTS
  The results of adrenal hormone tests (17-hydroxyprogesterone, 17-ketosteroids, and pregnanes) had been unsatisfactory, particularly over the previous 5 years. Scrotal ultrasound detected TARTs bilaterally. After increasing the dose of hydrocortisone and introducing dexamethasone, considerable regression of the tumors was noted.
  
  
  CONCLUSIONS
  Lack of complete regression of the lesions is caused by fibrosis and is probably due to decreased sensitivity of adrenocorticotropic hormone and angiotensin II receptors in this tissue.
