1/48. Surgical excision of a metastatic adrenal lesion in a patient with prostatic cancer.BACKGROUND: A 64-year-old Japanese man with stage D2 prostatic cancer, after having responded dramatically to androgen ablation, demonstrated a solitary adrenal metastasis without disease progression to any other site. methods: A surgical excision of the lesion and adjuvant systemic chemotherapy was performed. RESULTS/CONCLUSIONS: The patient has since remained alive without any evidence of recurrence 21 months after surgery.- - - - - - - - - - ranking = 1keywords = androgen (Clic here for more details about this article) |
2/48. hypertension and virilization caused by a unique desoxycorticosterone- and androgen-secreting adrenal adenoma.We describe a rare androgen and desoxycorticosterone (DOC)-secreting adrenal tumor in a non-Cushingoid 14 year-old Haitian girl with secondary amenorrhea, hypertension and virilization. Her steroid pattern simulated an 11 beta-hydroxylation defect with notable elevation of adrenal androgens, 11-desoxycortisol (S), DOC, 17 alpha-hydroxyprogesterone and pregnenelone. Exogenous ACTH stimulated steroidogenesis. A CAT scan unfortunately failed to delineate an adrenal mass. dexamethasone (DEX) was administered, therefore, which partially suppressed androgen levels, reduced DOC and S by 80% and 82% respectively, and normalized blood pressure. Nevertheless, the response to glucocorticoid was incomplete and an MRI was obtained, which revealed a right adrenal tumor. Post surgery, the patient promptly resumed menses and became normotensive. This case illustrates that ACTH and DEX cannot reliably differentiate tumor from hyperplasia, whereas the simultaneous increase of delta 4 and delta 5 steroids, present here, may favor a tumor. This case also allows speculation that the hypersecretion of DOC may result from inhibition of 11 beta-hydroxylase activity by excess androgens. The importance of appropriate imaging for diagnosis is underscored.- - - - - - - - - - ranking = 8keywords = androgen (Clic here for more details about this article) |
3/48. Adrenal adenocarcinoma and empty sella syndrome in a 37-year-old woman.The case of a 37-year-old woman with secondary amenorrhea and clear signs of hyperandrogenism is reported. The patient underwent hormonal evaluation including circadian rhythm of cortisol, gonadotropin-releasing hormone/thyroid-stimulating hormone (GnRH/TRH) test, corticotropic-releasing hormone (CRH) test and dexamethasone suppression test. She also underwent pelvic and adrenal ultrasound examination, adrenal computed axial tomography (CAT) scan and cranial nuclear magnetic resonance (NMR). A mass about 10 cm in size was detected in the left adrenal region. The sella was empty and the pituitary displaced downward. Suspected adrenal adenocarcinoma was confirmed by histological examination after surgical removal of the mass. This case is of interest for physicians because of the mixed androgen and cortisol secretion of the adenocarcinoma in a hyperprolactinemic patient with empty sella. Moreover, it suggests the need to investigate the adrenal gland in patients with hyperprolactinemia and hirsutism.- - - - - - - - - - ranking = 2keywords = androgen (Clic here for more details about this article) |
4/48. A young female patient with an androgen-secreting tumor: a rare malignant disease.A 23-year-old female patient presented with hirsutism and fatigue nine months after delivery. Endocrine assessment showed high testesterone, DHEA-S and androstenedione levels. Abdominal computed tomography and ultrasonography revealed the presence of a large tumor in the right renal region. Right adrenalectomy was performed resulting in a diagnosis of a functional adrenal tumor. Pathological examination showed a steroidogenically active tumor. Adjuvant chemotheraphy was administered postoperatively. At three months following surgery all endocrinological tests normalized, but liver metastases were detected by abdominal CT. Eight months after the operation the patient died of hepatic and renal failure. Androgen-secreting adrenal tumors are seen very rarely, yet the prognosis is poor due to their agressive nature.- - - - - - - - - - ranking = 4keywords = androgen (Clic here for more details about this article) |
5/48. Adrenal tumor presenting as precocious puberty.We present a case report of a two and a half-year-old boy who presented with precocious puberty. A clinical diagnosis of congenital adrenal hyperplasia was made. Patient was investigated and found to have an adrenocortical tumor. The tumor was about 7 cms in diameter. The tumor was secreting androgens, 17OHP and cortisol. This is an unusual array of hormones to be secreted by an adrenal tumor.- - - - - - - - - - ranking = 1keywords = androgen (Clic here for more details about this article) |
6/48. 17alpha-hydroxylase deficiency accompanied by adrenal myelolipoma.A 45-year-old woman was admitted because of hypertension and hypokalemia. Primary amenorrhea from birth was noted. plasma renin activity (PRA), 17alpha-hydroxyprogesterone and androgen levels were low, but progesterone, 11-deoxycorticosterone, corticosterone and adrenocorticotropic hormone (ACTH) were elevated, resulting in a diagnosis of 17alpha-hydroxylase deficiency. Abdominal magnetic resonance imaging revealed a round mass in the left adrenal region, the specimen of which was diagnosed as myelolipoma. After removal of the tumor, the blood pressure, serum potassium and hormone levels were unchanged, indicating an adrenal non-functioning tumor. Excessive ACTH secretion over a long period may stimulate the development of adrenal myelolipoma.- - - - - - - - - - ranking = 1keywords = androgen (Clic here for more details about this article) |
7/48. testosterone-secreting gonadotropin-responsive adrenal adenoma and its treatment with the antiandrogen flutamide.A 55-year-old woman with virilization had an appreciably elevated testosterone level, which was not suppressed by dexamethasone, but was increased by stimulation with human chorionic gonadotropin (hCG). ultrasonography and computed tomography revealed an adenoma 2.5-3.0 cm in diameter in the right adrenal gland. The patient was treated with the antiandrogen flutamide in a daily dose of 500 mg for 4 months. A substantial regression of her hirsutism was observed during flutamide administration, but the serum testosterone level remained high. Right adrenalectomy was performed. Histologically, the tumor proved to be an adrenocortical adenoma of zona reticularis type. The adenoma tissue contained specific hCG receptors (187 fmol/g). The steroid concentration in the tumor tissue was examined by means of high pressure liquid chromatography-radioimmunoassay (HPLC-RIA). A significantly increased testosterone content was detected, and the levels of its precursors, androstenedione and dehydroepiandrosterone, were also elevated. Following adrenalectomy, serum testosterone concentration decreased to the normal level. The mechanism of the inappropriate regulation in the testosterone production of the adrenal tumor has not been fully elucidated.- - - - - - - - - - ranking = 5keywords = androgen (Clic here for more details about this article) |
8/48. Hyperandrogenemia associated with insulin resistance mimicking an androgen producing tumor.The finding of a serum testosterone level greater than 200 ng/dl in a woman with virilization raises concerns about an androgen producing tumor. This case report demonstrates that chronic annovulation in association with insulin resistance can cause significant elevations in the level of serum testosterone, and describes the therapeutic benefit of insulin sensitizing agents in reversing hyperandrogenemia.- - - - - - - - - - ranking = 10keywords = androgen (Clic here for more details about this article) |
9/48. Unilateral adrenal tumor, erectile dysfunction and infertility in a patient with 21-hydroxylase deficiency: effects of glucocorticoid treatment and surgery.In untreated congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHDS) the presence of adrenal and testicular tumors had been described; however little is known about the effect of the enzymatic defect on fertility in males. We studied a male adult patient affected by 21OHDS for infertility, after a long period of discontinuation of glucocorticoid therapy and then during resumption of treatment and 8 months after monoadrenalectomy. The initial spermatic count revealed azoospermia and testicular needle aspiration showed a cytological picture consistent with prepuberty. The morphofunctional study revealed a right adrenal mass with reduced uptake at radioscan. Treatment was resumed with onset of impotency, which improved after reduction of the dose of glucocorticoids. The patient was monoadrenalectomised and his spermatic count increased. The patient shows that corticosteroid therapy in 21OHDS should be continued lifelong to avoid adrenal hyperplasia with possible areas of autonomy and to allow regular fertility. Impotence during treatment is probably due to a decrease of excessive adrenal androgens while testicular androgen production is still suppressed.- - - - - - - - - - ranking = 2keywords = androgen (Clic here for more details about this article) |
10/48. Manifestation of thyrotoxic periodic paralysis in two patients with adrenal adenomas and hyperandrogenaemia.Hypokalaemic periodic paralysis is a fairly common complication of hyperthyroidism in Asian populations, but a rare event in Caucasians. In the present work we describe 2 male Caucasian patients with thyrotoxic periodic paralysis (TPP) as initial clinical manifestation of Graves' disease. Further diagnostic procedures demonstrated unilateral adrenal adenoma and hyperandrogenaemia in both patients. To date, only few data are available concerning the hormonal status of Caucasian patients with TPP. The constellation of TPP and adrenal adenomas with increased levels of androgens has not been described previously. Since androgens are capable of inducing sodium-potassium ATPase, which is thought to be centrally involved in the pathogenesis of TPP, hyperandrogenaemia may have triggered the manifestation of paralytic attacks in our patients. It may be of interest to focus not only on thyroid dysbalances in patients with TTP but also to investigate other hormonal disturbances.- - - - - - - - - - ranking = 8keywords = androgen (Clic here for more details about this article) |
