[A case of bilateral testicular tumors with congenital adrenal hyperplasia].

We report a case of congenital adrenal hyperplasia (CAH) occurring in a 21-year-old man. He was found to have 21-hydroxylase deficiency shortly after birth in search for the cause of vomiting and adrenal insufficiency, and placed on steroid therapy. He had an uneventful childhood with normal onset of puberty. At the age of 21 years he was hospitalized with bilateral testicular masses. They were non-tender, firm and nodular on palpation. The levels of adrenocorticotrophic hormone (ACTH), 17 alpha-hydroxyprogesterone (17 alpha-OHP) were found to be elevated. Testicular biopsy revealed that the nodule comprised mainly eosinophilic sheets and nests and polygonal cells with abundant, granular cytoplasm, but no crystals of Reinke were seen. Testicular tumor with congenital adrenal hyperplasia is typically bilateral and develops in untreated or inadequately treated males with CAH.
