1/47. Use of a long-acting gonadotrophin-releasing hormone analogue in a postmenopausal woman with hyperandrogenism due to a hilus cell tumour.OBJECTIVE: The aim of this study was to prove the utility of GnRH analogues for the suppression of androgen secretion in a postmenopausal woman with a suspected virilizing ovarian tumour. DESIGN AND methods: We present a case of a 72-year-old woman with virilization of recent onset. Hormonal studies revealed a fourfold increase in serum testosterone levels, normal dehydroepiandrosterone sulphate concentrations and high levels of serum 17-hydroxyprogesterone levels. Computed axial tomography scan of the ovaries was normal and the adrenal glands showed a discrete enlargement. The long-acting GnRH analogue, triptorelin, was injected initially (3.75mg i.m.) and serum hormone levels were measured weekly throughout one month. RESULTS: GnRH produced a decrease in serum testosterone levels to normal values, in parallel with the suppression of serum LH and FSH concentrations. The patient was treated for three months with triptorelin and she experienced an amelioration of the hyperandrogenic symptoms. In order to achieve a diagnosis, the patient was submitted to a laparotomy that revealed a small hilus cell tumour in the left ovary. CONCLUSION: GnRH analogues may offer a good therapeutic option in some states of gonadotrophin-dependent hyperandrogenism of ovarian origin.- - - - - - - - - - ranking = 1keywords = ovary (Clic here for more details about this article) |
2/47. Extremely high levels of estradiol and testosterone in a case of polycystic ovarian syndrome. Hormone and clinical similarities with the phenotype of the alpha estrogen receptor null mice.A 19-year-old nulliparous hirsute woman was evaluated for the very high serum levels of testosterone (T) and estradiol (E2) measured in an outside laboratory. menarche had occurred at 11 years and was followed by regular menses. We confirmed the high levels of T (9-16 ng/ml, nv 0.2-0.8) and E2 (>1,000 pg/ml, nv 30-120). LH and FSH were consistently high (73-118 mU/l and 18-29 mU/l, respectively; LH/FSH ratio=4.1-4.7) and responsive to iv GnRH (LH baseline=118 mU/I, 30 min=290; FSH baseline=25 mU/l, 30 min=46). The unstimulated values contrasted with those (LH=12, FSH=8 mU/I) measured in the outside laboratory, suggesting antigenically anomalous gonadotropins. 17-OH-progesterone was normal (0.5 ng/ml). After 1 mg dexamethasone, serum cortisol was normally suppressed (24-->0.4 microg/dl), T declined minimally (9-->8.6 ng/ml) and E2 remained high (>1,000 pg/ml). An exploratory laparotomy was performed, and two enlarged ovaries with multiple cysts as in a typical polycystic ovarian syndrome (PCOS) were seen. Before the wedge resection of the ovaries, hormones were assayed in the ovary veins (right ovary: T=30 ng/ml, Pg=17 ng/ml, E2=>5,000 pg/ml; left: T=14 ng/ml, Pg=14 ng/ml, E2=>5,000 pg/ml). Histologically, the follicle cysts showed luteinization of the theca interna; there was no evidence for ovary tumor in either ovary. After 21 days of 35 microg ethynyl-E2 2 mg cyproterone acetate (CA), E2=3,000 pg/ml, T=1.4 ng/ml, LH=10.5 mU/l and FSH=4.1 mU/I. After three cycles of the said therapy (but with 50 mg CA in the first 10 days of each cycle), E2 was 1,600 pg/ml, T 1.7 ng/ml, LH 7.1 and FSH 4.6 mU/I. Based on similarities with the phenotype of the alpha estrogen receptor knockout female mice (alphaERKO), one possible explanation for the puzzling clinical and biochemical picture of our patient is resistance of (alphaER to estrogens. This is the first case of PCOS with extremely high E2 and T. Thus, the differential diagnosis of high levels of E2 /- T should include PCOS.- - - - - - - - - - ranking = 23.605766721863keywords = polycystic, ovary (Clic here for more details about this article) |
3/47. Laparoscopic management of Sertoli-Leydig cell tumors of the ovary. A report of two cases.BACKGROUND: sertoli-leydig cell tumor is a rare ovarian tumor with an incidence of < .5% of all ovarian tumors. laparotomy is the standard approach to these cases. CASES: Sertoli-Leydig cell tumors were diagnosed in two young, nulliparous, infertile women. Both presented with secondary amenorrhea. Virilization was found in one. Their testosterone levels were high, and sonography revealed a solid, echogenic mass in the fornix. Laparoscopic removal was performed. Both women achieved normal menstruation one month after the operation, and one became pregnant and gave birth to a healthy infant. CONCLUSION: There are very few case reports of laparoscopic removal of such tumors. Laparoscopic surgery, which is minimally invasive and cosmetically acceptable and has a speedy recovery, should be the approach of choice for these patients.- - - - - - - - - - ranking = 4keywords = ovary (Clic here for more details about this article) |
4/47. polycystic ovary syndrome: a case presentation.polycystic ovary syndrome (PCOS) is a disorder of excessive adrenal hormone production that results in characteristic features. It is associated with hyperinsulinemia and, if left untreated, carries a risk for developing such complications as diabetes and heart disease. The clinical features are described here by means of a case presentation. Using the Ferriman-Gallwey score, the degree of hirsutism is identified. Differential diagnoses and recommended treatments are discussed. The role of the advanced practice nurse in the diagnosis and care of patients with PCOS is included.- - - - - - - - - - ranking = 433.58187721327keywords = ovary syndrome, ovary (Clic here for more details about this article) |
5/47. Intraoperative testosterone assay for virilizing ovarian tumor topographic assessment: report of a Leydig cell tumor of the ovary in a premenopausal woman with an adrenal incidentaloma.Ovarian virilizing tumors are rare and can lead to assessment difficulties because of their small size. A 41-yr-old female was referred for evaluation of hirsutism that had increased within the previous 3 yr. menstrual cycle length was normal. plasma testosterone was 3.9 ng/ml (normal range, 0.2-0.8 ng/ml), was not suppressible by 2 mg dexamethasone (4.3 ng/ml), and was increased (6.3 ng/ml) after three daily injections of hCG (5000 IU). Abdominal computed tomography scan showed an adrenal nodule (13 x 6 mm) that remained unchanged after 3 months. Ultrasound examination of the pelvis was normal. Ovarian and adrenal venous catheterization did not yield additional information. Topographic assessment was made by intraoperative measurement of testosterone in the samples taken from each ovarian vein (competitive chemiluminescent immunoassay ADVIA Centaur; right ovarian vein, 105 ng/ml; left ovarian vein, 5 ng/ml; peripheral blood, 7 ng/ml). Right annexectomy resulted in normalization of testosterone levels (0.22 ng/ml). Histopathological examination found a Leydig cell tumor of hilar type (1.5 cm). This observation illustrates the usefulness of intraoperative measurement of testosterone by a rapid automated technique for topographic assessment of ovarian virilizing tumor in premenopausal women.- - - - - - - - - - ranking = 4keywords = ovary (Clic here for more details about this article) |
6/47. Androgen-secreting adrenal adenomas.BACKGROUND: The androgen source in women with hirsutism and signs of virilism may be the ovary or adrenal gland. CASES: Three patients with androgen excess are reported. Two had hyperandrogenemia and cushing syndrome with an adrenal mass greater than 5.5 cm; the third had a small adrenal adenoma secreting only testosterone and responsive to human chorionic gonadotropin. In all cases, the pathologic report from surgery and the long-term resolution of symptoms confirmed the benign nature of the tumors. CONCLUSION: Basal and dynamic hormonal tests cannot precisely differentiate ovarian from adrenal tumors. Adrenal adenomas must be considered as a cause of hyperandrogenic syndrome.- - - - - - - - - - ranking = 1keywords = ovary (Clic here for more details about this article) |
7/47. insulinoma presenting with hyperandrogenism: a case report and a literature review.An 18-year-old woman presented with a 6-month history of amenorrhoea and hyperandrogenism. Three months later she developed several episodes of fasting hypoglycaemia and was subsequently diagnosed with an insulinoma. Hyperinsulinaemia was observed in association with an elevated serum testosterone level. Surgical removal of the insulinoma resulted in resolution of the clinical and biochemical features of the polycystic ovarian syndrome (PCOS). Polycystic ovarian syndrome is unusual in a patient having an insulinoma. The rarity of this association may be the result of the late age of onset of this type of tumour, intermittent secretion of excessive insulin by the tumour, the degree of hyperinsulinism or other factors extrinsic to the insulin receptor that may facilitate insulin activity. However, we could not discover how our patient differs in having had PCOS from the majority of women with insulinoma who do not. If other patients with insulinoma are subsequently found to have hyperandrogenism, then this tumour might be added to the differential diagnosis of causes of anovulatory cycles and hyperandrogenaemia, although rare the association would be uncommon.- - - - - - - - - - ranking = 3.9211533443726keywords = polycystic (Clic here for more details about this article) |
8/47. diagnosis of a small, androgenizing Brenner cell tumor in a postmenopausal woman aided by laparoscopic salpingo-oophorectomy. A case report.BACKGROUND: Rapidly progressive hirsutism or virilization in the postmenopausal woman raises the suspicion of an androgen-secreting tumor. Hormonal testing and imaging studies usually rule out an adrenal tumor. However, small, androgenizing ovarian tumors may not be detectable by imaging studies. CASE: A postmenopausal woman presented with rapidly progressive hirsutism and elevated androgens. Imaging studies did not localize the tumor. Bilateral laparoscopic oophorectomy was performed, and a small, androgenizing Brenner cell tumor of the left ovary was demonstrated on histologic examination. CONCLUSION: Because of the low morbidity associated with laparoscopic salpingo-oophorectomy, it may be reasonable to remove the ovaries of postmenopausal women who display virilization or rapidly progressive hirsutism and elevated androgens, even if imaging studies do not detect the ovarian tumor.- - - - - - - - - - ranking = 1keywords = ovary (Clic here for more details about this article) |
9/47. Sclerosing stromal tumor of the ovary: a case report.Sclerozing stromal tumor of the ovary is an extremely rare neoplasm occurring predominantly in the second and third decades of life. Most patients have menstrual irregularities and pelvic pain. infertility and endometrial pathology have also been described. A 34-year-old woman presented with hirsutism and oligomenorrhea of three months duration. Ultrasound examination showed a heterogeneous right ovarian tumor consisting of predominantly solid tissue with several loculated cysts. On T2-weighted pelvic MR images, signal intensities of the cystic components were high and those of the solid components were heterogeneous, ranging from intermediate-high to high. Dynamic MRI marked early enhancement of solid components in the right ovary. The specimen obtained from endometrial curettage showed proliferative endometrium. Preoperative serum levels of tumor markers were in normal range: preoperative serum levels of testosterone (T) (2.42 ng/ml; normal for adult females 0.1-0.8 ng/ml) and dehydroepiandrosterone-sulphate (DHEA-S) (232.4 microg/dL; normal for adult female, 35-430 microg/dL) were measured and the T value was found increased. At laparotomy, a left ovarian mass was found attached to the right infundibulopelvic ligament and a left oophorectomy was performed. The mass was described as benign by frozen analysis. Definitive histopathological diagnosis was sclerozing stromal tumor of the ovary (SST). The histologic features included a pseudolobular pattern with focal areas of sclerosis and a two-cell population of spindled and polygonal cells. Immunohistochemical studies showed positive smooth muscle actin and negative cytokeratin, keratin, S100 and desmin. The T value decreased postoperatively (0.57 ng/ml).- - - - - - - - - - ranking = 7keywords = ovary (Clic here for more details about this article) |
10/47. Coincidental diagnosis of an occult hilar steroid cell tumor of the ovary and a cortisol-secreting adrenal adenoma in a 49-year-old woman with severe hyperandrogenism.OBJECTIVE: To report an exceptional association between an occult ovarian steroid cell tumor and a cortisol-secreting adrenal adenoma. DESIGN: Case report. SETTING: endocrinology and nutrition unit at a general hospital in spain. PATIENT(S): A 49-year-old woman who presented with persistence of severe hyperandrogenism after removal of a left adrenal adenoma. INTERVENTION(S): An endocrine study evaluating serum androgens, adrenal function, and tumor markers was ordered. Transvaginal sonography was done to rule out an ovarian tumor. Finally, a selective catheterization of ovarian veins allowed the correct diagnosis. MAIN OUTCOME MEASURE(S): Clinical and endocrine description of the patient and preoperative localization of the source of T secretion. RESULT(S): After adrenal surgery, urinary free cortisol levels decreased to normal values, but serum T remained within the tumoral range (3.04 ng/mL). Selective catheterization of ovarian veins revealed a gradient of T concentration in the right ovary. After bilateral annexectomy, a microscopic steroid cell tumor of hilar type was found in the right ovary. serum T fell within the normal range, and hirsutism progressively improved. CONCLUSION(S): This unusual association between an occult-virilizing ovarian steroid cell tumor and a cortisol-secreting adrenal adenoma illustrates the value of an accurate preoperative workup in women with severe hyperandrogenism.- - - - - - - - - - ranking = 6keywords = ovary (Clic here for more details about this article) |
