Excessive testosterone production in a patient with Nelson syndrome and bilateral testicular tumors.
|
| Abstract |
Bilateral primary testicular tumors are rare and usually consist of either interstitial cells or hypertrophic testicular adrenal remnant tissue. Their differentiation on clinical presentation and histologic examination remains difficult but is essential because of the different therapeutic approaches. We report a rare case of excessive testosterone production by bilateral testicular tumors in a patient with Nelson syndrome (ACTH-secreting pituitary adenoma after bilateral adrenalectomy in patients with Cushing's disease). Increased ACTH stimulation in this patient supports the thesis of pluripotent cells within the testis which can undergo differentiation to cells which are not only morphologically similar to Leydig cells but also have the functional property of these cells. Our clinical findings support the diagnosis of hyperplasia of adrenal remnant or pluripotent cells rather than a true Leydig cell tumor. We emphasize the need for hormonal evaluations which should be assessed in the context of the size of these nodular tumors prior to therapeutic decisions. In cases with elevated serum ACTH and small nodular hyperplasia, we would favor a 'wait-and-see' strategy with appropriate hormonal therapy. In large tumors with clinical signs of hormonal activity, patient noncompliance with steroid replacement regimens or with local symptoms, scrotal exploration and tumor enucleation are indicated.
