[Testicular adrenal rest tumor in the background of congenital adrenal hyperplasia].

The prevalence of testicular adrenal rest tumours varies in different forms of congenital adrenal hyperplasia. Patients with 21-hydroxilase deficiency usually have bilateral and palpable testicular nodules. Although adrenal rest tumours are well documented in the literature, the diagnosis and management require a multidisciplinary approach: the cooperative work of endocrinologists, urologists, pathologists and radiologists is essential. In the case of an early diagnosis, appropriately increased corticosteroid treatment may reduce the tumour mass. In advanced stages, tumours can lead to irreversible parenchymal damage causing infertility. The importance of an early and accurate diagnosis cannot be emphasized enough, since the therapy differs significantly from other benign or malignant testicular neoplasia. A case of a testicular adrenal rest tumour is presented along with the multidisciplinary perspectives of the diagnosis and management of these lesions.
