Introduction: Male patients with congenital adrenal hyperplasia may develop testicular adrenal rest tumors, with an increasing prevalence rate observed during and after puberty. The etiology of these benign lesions is unclear, but possibilities include adrenal rests and pluripotent ectopic adrenal cortex remnant cells of the testicular stroma which differentiate and grow under the influence of chronically elevated adrenocorticotropic hormone.
Methods: Case report based on literature review.
Results and conclusion: We report a case of a 12-year-old male patient with the neonatal diagnosis of congenital adrenal hyperplasia and a 6-hour history of acute scrotal pain after a minor blunt trauma during rugby practice. Physical examination was normal. Ultrasound revealed one round and homogeneously hypoechoic nodule in each testicle, interpreted as testicular adrenal rest tumors. One year after the diagnosis, the patient is asymptomatic and the size and number of lesions remain stable at follow-up ultrasound. The recognition of this benign entity in the adequate clinical context will help prevent unnecessary orchiectomies.
