Tumores testiculares bilaterais por hiperplasia congênita de restos adrenais Bilateral testicular tumors caused by congenital adrenal rest hyperplasia

1 , ABSTRACT Objectives: Testicular tumors are a rare condition associated with congenital adrenal hyperplasia (CAH), originated from intratesticular adrenal rest tumors, and they are rarely associated with malignant tumors. Their histological differentiation from Leydig-cell tumors is quite difficult, whi - ch would lead to inappropriate orchiectomies. Thus the objective of this report was to present this diagnostic dilemma. Methods: Reported the case of 16-yr-old boy with previous diagnosis of CAH with bilateral testicular enlargement who was recommended to be submitted to a bi- lateral orchiectomy. Results: Considering this findings, it was decided to treat conventionally with prednisone with significant reduction of testicular volume, and normalization of androgens levels. Conclusion: This case shows the importance of intratesticular adrenal rest tumors in the differential diagnosis of testicular tumors. Cautious approach during investigation and treatment are recommended to avoid inappropriate orchiectomies. Arq Bras Endocrinol Metab. 2009;53(8):1052-8
