Total testosterone and DHEAS levels as predictors of androgen-secreting neoplasms: a populational study

Postmenopausal onset of androgen excess: a diagnostic and therapeutic algorithm based on extensive clinical experience

PURPOSE

Postmenopausal hyperandrogenism is a rare condition that requires identifying those women bearing a life-threatening tumor. We aimed to study diagnostic work-up and management of postmenopausal androgen excess, proposing an algorithm for clinical decision supporting.

METHODS

We conducted an observational cross-sectional study and longitudinal follow-up including 51 consecutive menopausal patients reported for hyperandrogenism between 2003 and 2023 to our clinics. We assessed diagnostic testing accuracy and performance by receiver operating characteristic curves, their respective areas under the curve (AUCROC), and 95% confidence intervals (95%CI), for distinguishing between benign and malignant conditions, and androgen excess source.

RESULTS

Most commonly, postmenopausal hyperandrogenism derived from benign conditions such as ovarian hyperthecosis (n = 9). However, four (8%) patients had borderline/malignant tumors arising at the ovaries (n = 3) or adrenals (n = 1). These latter were more likely to develop virilization than those with benign disorders [specificity(95%CI)]: 0.87 (0.69; 0.92)]. Circulating total testosterone [AUCROC(95%CI): 0.899 (0.795; 1.000)] and estradiol [AUCROC(95%CI): 0.912 (0.812; 1.000)] concentrations showed good performances for discriminating between both conditions. Transvaginal-ultrasonography found two out of three potentially malignant ovarian neoplasms, and another was apparent on a pelvic computed tomography scan. An adrenal computed tomography scan also located an androgen-secreting carcinoma.

CONCLUSIONS

Clinical or biochemical features of an aggressive androgen-secreting tumor should lead to urgently obtaining a targeted imaging. At first, an abdominal-pelvic CT scan represents the best choice to perceive adrenal malignancy, and may identify aggressive ovarian tumors. When warning signs are lacking, a calm and orderly work-up allows properly addressing the diagnostic challenge of postmenopausal hyperandrogenism.

Ovarian steroid cell tumor (not otherwise specified) with subsequent spontaneous pregnancy after tumor removal: a case report and literature review

Steroid cell tumors not otherwise specified are rare sex cord-stromal tumors of the ovary that may produce various steroids and are associated with hirsutism and virilization. We report a rare case of ovarian steroid cell tumor with subsequent spontaneous pregnancy after tumor removal. A 31-year-old woman presented with secondary amenorrhea, hirsutism, and inability to conceive. Clinical and diagnostic evaluations revealed a left adnexal mass and elevated serum total testosterone and 17α-hydroxyprogesterone levels. She underwent a left salpingo-oophorectomy, and histopathological examination confirmed the diagnosis of a steroid cell tumor not otherwise specified. Her serum total testosterone and 17α-hydroxyprogesterone normalized one month after surgery. Her menses resumed spontaneously one month after the operation. She spontaneously conceived 12 months after the surgery. The patient had an uncomplicated pregnancy and delivered a healthy male infant. In addition, we reviewed the literature on steroid cell tumors not otherwise specified with subsequent spontaneous pregnancies after surgery and data regarding pregnancy outcomes.

A Rare Case of Hyperandrogenism Due to Fibrothecoma and Leydig Cell Tumor in a Postmenopausal Woman With Adrenal Adenoma: A Case Report and Literature Review

Hyperandrogenism is an endocrine disorder characterized by an elevated level of androgen in women, which can be due to several etiologies, including ovarian and adrenal causes. Hyperandrogenism can result in hirsutism and virilization in severe cases. Ovarian etiologies can include ovarian hyperthecosis, hilus cell tumors, arrhenoblastomas, and Leydig cell tumors. Diagnosing the specific cause requires comprehensive work, and management is then tailored to address the specific etiology. Treatment may include bilateral oophorectomy and gonadotropin-releasing hormone (GnRH) analogs in combination with antiandrogen therapy. Surgery, medical treatment, and radiation therapy are also options for patients with hypercortisolemia. We present the case of a 58-year-old female who presented with clinical features of hyperandrogenism, which were confirmed with biochemical testing. She was found to have a non-functioning adrenal adenoma with no significant abnormality on ovarian imaging and biochemical hyperandrogenemia due to fibrothecoma and Leydig cell tumor, which resolved after bilateral salpingo-oophorectomy.

Bilateral Leydig Cell Hyperplasia: A Rare Cause of Postmenopausal Hirsutism

Background

Postmenopausal hirsutism could be due to a myriad of causes, including ovarian and adrenal tumours, ovarian hyperthecosis, exogenous androgens, and Cushing's syndrome. We report a patient who was found to have a rare cause of postmenopausal hirsutism. Case Presentation. A 64-year-old postmenopausal woman with a history of hypertension, thyrotoxicosis, and poorly controlled diabetes on multiple oral hypoglycaemic agents presented with gradual onset progressive excessive hair growth without any virilizing features. On examination, she did not have Cushingnoid features or clitoromegaly. Her hirsutism was quantified with Ferriman–Gallwey score which was 9. Her biochemical evaluation showed elevated testosterone levels with normal DHEAS, ODST, 17-OHP, and prolactin. Low-dose dexamethasone suppression test did not suppress testosterone more than 40%. Contrast-enhanced CT of the adrenal and pelvis did not show any adrenal or ovarian mass lesions. Transvaginal ultrasound scan showed bilateral prominent ovaries only. Combined adrenal and ovarian venous sampling was carried out to localize the source of excess androgen, but only the left adrenal vein was successfully cannulated which showed suppressed testosterone level compared to periphery. The patient underwent total abdominal hysterectomy and bilateral salphingo oophorectomy, and her testosterone level normalized postoperatively. Her glycaemic control improved. Histology showed evidence of bilateral diffuse ovarian Leydig cell hyperplasia.

Conclusion

Evaluation of postmenopausal hirsutism needs careful history and examination followed by biochemical evaluation and imaging. While adrenal and ovarian venous sampling can help to arrive at a diagnosis, it is a technically demanding procedure with low success rates even at centers of excellence. Therefore, in such situations, bilateral oophorectomy may be the best course of action which will give the histological confirmation of the diagnosis. Successful treatment of hyperandrogenism can result in improvement of glycaemic control. Bilateral diffuse Leydig cell hyperplasia is a rare but important cause of postmenopausal hirsutism.

Central precocious puberty after resection of a virilising adrenocortical oncocytic tumour

Adrenocortical oncocytic tumours are a histological subtype of adrenal neoplasms with a distinctive morphological appearance. Since these tumours are composed of cells of the adrenal cortex, they may act as functional tumours with excess hormone production. They may cause Cushing's syndrome, inappropriate virilisation or precocious puberty. Though rare during childhood, adrenocortical oncocytic tumours should be suspected in a child with peripheral precocious puberty and marked elevation of dehydroepiandrosterone sulfate levels. We describe a 6-year girl who presented with peripheral precocious puberty due to a functional adrenocortical oncocytic tumour. Three months after tumour removal, she developed true central precocious puberty. This report highlights that peripheral precocious puberty may trigger central precocious puberty, particularly after resolution of the underlying cause of the peripheral precocious puberty.

Sertoli-Leydig cell tumour in a patient with non-classic congenital adrenal hyperplasia: an uncommon duo

Polycystic ovary syndrome is the most common cause of hyperandrogenism in young females. Other causes are congenital adrenal hyperplasia (CAH), androgen-producing tumours and drugs. The severity and tempo of virilisation help in distinguishing the tumoural from non-tumoural causes. We report a rare case of non-classic CAH and androgen-producing ovarian tumour in the same patient, causing hyperandrogenism. A 15-year-old female patient presented with secondary amenorrhea, excessive facial hair growth and clitoromegaly for 6 months. Due to severe virilisation, tumoural aetiology was considered. Investigations showed marked elevation of testosterone and mild elevation of 17 hydroxy progesterone (17OHP). Imaging confirmed right ovarian tumour. Adrenocorticotropic hormone stimulated 17OHP, was elevated confirming the diagnosis of underlying non-classic CAH. Surgical removal of the tumour was followed by improvement in hyperandrogenism, but persistent elevation of 17OHP confirmed the underlying presence of non-classic CAH.

Contemporary Management of Polycystic Ovarian Syndrome

PCOS remains one of the most intriguing endocrine disorders that physicians encounter even though it was first described over 80 years ago. Although the diagnostic criteria, nomenclature, and ideal therapeutic strategies are areas of active and ongoing debate, there is no doubt that we have made tremendous progress in improving the quality of life and reproductive outcomes of women who suffer from this wide-ranging disorder.

Paraneoplastic syndromes and other systemic disorders associated with neuroendocrine neoplasms

Neuroendocrine paraneoplastic syndromes (PNS) consist of metabolic disorders that accompany benign and malignant neoplasms but remain unrelated to mass effects or invasion by the primary tumor or its metastases. The underlying pathogenesis responsible for PNS usual clinical presentation relies on aberrant production of protein hormones, proteins and other substances by the tumor. Prompt recognition of characteristic signs and symptoms combined with serological identification of key substances may result in early diagnosis of PNS and its underlying malignancy. For these reasons, healthcare professionals should familiarize themselves with tumor-induced hypercalcemia, syndrome of inappropriate antidiuretic hormone, carcinoid syndrome, virilisation syndrome, gynecomastia, acromegaly, Cushing syndrome, osteogenic osteomalacia, tumor-induced hypoglycemia, necrolytic migratory erythema, and watery diarrhea, hypokalemia and achlorydria syndrome. Medical awareness for PNS can improve patient outcomes through earlier administration of cancer therapy and treatment, better symptomatic relief and prolong overall survival.

An unusual circulating steroid profile in a virilized postmenopausal woman

BACKGROUND

Virilism is a female disorder in which secondary male sexual characteristics develop, caused by an excessive adrenal or ovarian androgen secretion.

CASE PRESENTATION

Here, we report an unusual case of an ovarian steroid cell tumor, not otherwise specified (NOS), in a 68-year-old female who presented with androgenic alopecia, clitoromegaly and an increased muscle mass. Laboratory investigations revealed both ovarian and adrenal hyperandrogenism with an elevation of androgen precursors mimicking congenital adrenal hyperplasia. A left adnexal mass was confirmed by imaging techniques. A laparoscopic bilateral salpingo-oophorectomy was performed and histopathology confirmed the diagnosis of an ovarian steroid cell tumor NOS. After surgical intervention, circulating androgen levels and their precursors returned to normal values in the postmenopausal woman.

CONCLUSIONS

A detailed anamnesis and physical examination are key to the correct diagnosis in a woman with hyperandrogenism independent of her circulating androgen profile.

Diagnostic Dilemma in Two Cases of Hyperandrogenism

Hirsutism is a common endocrine complaint affecting about 10 percent of women. It may be caused by multiple etiologies including adrenal and ovarian disorders. Usually, it is a result of a benign entity such as PCOs and idiopathic hirsutism. However, sometimes especially when it is severe and rapid in progression an androgen-secreting tumor should be excluded. Sertoli-Leydig cell tumors constitute fewer than 0.5 percent of ovarian tumors and it may be benign or malignant. In this article, we present two cases of hyperandrogenism caused by occult ovarian Leydig cell tumors. one of them was confounded by the presence of coincidental bilateral adrenal nodules that complicated the diagnostic process. Tumor dissection was curative in both cases and the diagnosis was confirmed by pathological and hormonal testing after surgery.

Case report: an identical twin with Sertoli-Leydig cell tumor

Our report details the workup and management of a 43-year-old woman with an identical twin who presented with 2 years of virilization and secondary amenorrhea. Serum total testosterone was elevated. An MRI did not identify adnexal or adrenal pathology. Subsequent ovarian vein sampling demonstrated unilateral testosterone elevation. The patient underwent laparoscopic unilateral oophorectomy resulting in the diagnosis of Sertoli-Leydig cell tumor (SLCT). Although SLCT is a rare sex-cord ovarian tumor, it is associated with endometrial hyperplasia and malignancy. Our goals are to review the workup of androgen-secreting tumors and discuss the clinical importance of the DICER1 mutation in the context of SLCT. In this case, an identical twin underwent DICER1 testing which was one of the essential steps in her clinical management.

An ovarian Leydig cell tumor of ultrasound negative in a postmenopausal woman with hirsutism and hyperandrogenism: A case report

RATIONALE

The incidence of severe hyperandrogenism associated with masculinity in women is very low. While rare and difficult to diagnose, androgen secreting tumors should be suspected in women with hyperandrogenism and hirsutism, especially in the postmenopausal population. Herein we present one case of ovarian Leydig cell tumor (LCT) with markedly elevated serum testosterone levels and frank hirsutism.

PATIENT CONCERNS

A 60-year-old woman, presented with increased hair growth and androgenic alopecia and the hormonal laboratory examination showed that she had elevated serum testosterone level and normal dehydroepiandrosterone sulfate (DHEAS), androstenedione, 17- hydroxyprogesterone, cortisol and thyroid stimulating hormone (TSH).

DIAGNOSES

The diagnosis of possible testosterone secreting tumor was performed when pelvic computed tomography (CT) and magnetic resonance image (MRI) showed a right adnexal mass of 15mm×16mm indicative of sex cord- stromal tumors.

INTERVENTIONS

The patient received laparoscopic total abdominal hysterectomy and bilateral salpingo-oophorectomy.

OUTCOMES

After operation, testosterone got back to the normal level and clinical symptoms subsided.

LESSONS

It is common that postmenopausal androgen excess is a state of relative or absolute androgen excess originating from the adrenal gland and/or ovaries. In either case, doctors need to assess such patients and exclude relatively rare potential causes of tumors. Any woman who has hirsutism or frank evidence of markedly increased testosterone should exclude this kind of possibility of androgen producing tumors. It is possible to determine the origin of androgen hypersecretion with the severity of symptoms, the extent of androgen excess, and the relevant imaging studies. Since LCT are rare ovarian sex-cord stromal tumors, it can be beneficial for diagnosis with careful research of patient history of the defeminization followed by virilization, and a CT and MRI image.

Total testosterone levels are often more than three times elevated in patients with androgen-secreting tumours

Hirsutism is present in up to 25% reproductive aged women and is most often caused by polycystic ovary syndrome. Less than 5% of patients with hirsutism are diagnosed with rare endocrine diseases including ovarian or adrenal androgen-producing tumours, but these tumours may be malignant and need surgery. Terminal hair growth on lip and chin gradually increases after menopause, which complicates distinction from normal physiological variation. Precise testosterone assays have just recently become available in the daily clinic. We present three women diagnosed with testosterone-producing tumours. Gold standard techniques were used to measure testosterone levels. All tumours originated from the ovaries. Based on the present cases and the existing literature, we suggest that androgen-producing tumours should be suspected in patients with rapid progression of hyperandrogen symptoms, particularly when total testosterone levels are above three times the upper reference limit.

Hyperandrogenism in post-menopausal women: a diagnosis challenge

A 79-year-old woman, presented with increased hair growth in the chin and the upper lip but no in other androgen-dependent areas of her body. Hormonal evaluation showed markedly elevated serum testosterone level (>1.7 ng/ml) and normal DHEA-S, androstenedione, 17-hydroxyprogesterone, cortisol and TSH levels. The diagnosis of probable pure testosterone secreting tumor was made. Transvaginal ultrasound and magnetic resonance image revealed a 16 mm × 12 mm nodular formation indicative of an atypical adenoma in the left adrenal gland and a tube-shaped, fluid-filled, thin-walled image measuring 28 mm × 14 mm suggestive of a hydrosalpinx in the right ovary. Differential diagnosis between the coexistence of an androgen-producing ovarian tumor (occult) associated with a finding of an adrenal image (Incidentaloma) or an adrenal tumor secreting testosterone only was done. Since cortisol levels went down, but total testosterone inhibition did not occur after suppression with dexamethasone. An ovarian androgen secreting tumour was suspected and surgery was performed. Histological examination showed a Leydig cells hyperplasia. After the operation testosterone returned to normal with regression of clinical symptoms.

Leydig cell hyperplasia and Leydig cell tumour in postmenopausal women: report of two cases

Leydig cell hyperplasia and Leydig cell tumours of the ovary are rare. We present two cases in which patients had increased blood levels of testosterone and frank hirsutism. Imaging showed minimal abnormalities. After adrenal disease had been ruled out, they underwent a bilateral oophorectomy. One case showed a Leydig cell hyperplasia, the other a Leydig cell tumour. An androgen producing tumour should be excluded in every woman with evidence of hirsutism or frank virilization and markedly elevated testosterone levels. Adrenal disease with androgen hypersecretion can be suspected by detailed clinical, laboratory and radiologic imaging. Although DHEAS has a good sensitivity in the detection of adrenal origin of hyperandrogenism (and hence a good negative predictive value) it is not specific (specificity ranging from 85 to 98%). Imaging of the ovaries can be helpful but does not rule out ovarian disease if normal. Indeed, diffuse stromal Leydig cell hyperplasia and Leydig cell tumours (usually small) may escape imaging and in some cases diagnosis can only be made on pathology. As these clinical entities represent a diagnostic and therapeutic challenge, oophorectomy should be considered in postmenopausal women with hirsutism and elevated testosterone levels, after the exclusion of adrenal causes. The procedure is relatively safe and effective. Follow-up remains indicated.

Malignant ovarian Sertoli-Leydig cell tumor localized with selective ovarian vein sampling

Sertoli-Leydig cell tumors (SLCT) are rare, comprising less than 0.5% of ovarian neoplasms. They are most often diagnosed in premenopausal women and may produce androgens, resulting in hirsuitism, voice deepening, frontal balding, terminal hair growth, and clitoromegaly. SLCT are malignant in 15%-20% of cases. We discuss a 25-year-old patient with persistent hyperandrogenemia. Noninvasive imaging cannot conclusively differentiate between SCLT and other diagnoses such as polycystic ovary syndrome, ovarian hyperthecosis, idiopathic hyperandrogenism, idiopathic hirsuitism, and 21-hydroxylase-deficient nonclassic adrenal hyperplasia. Selective ovarian vein sampling revealed a 15-fold greater testosterone production from the right ovary compared with the left, which guided appropriate surgical management.

How to diagnose and treat medically women with excessive hair

Excessive hair growth in women is common and due to a broad spectrum of causes. Management options comprise different pharmaceuticals, epilation methods, and aesthetic approaches. Because excessive hair growth in women may cause psychological and psychosocial problems, a holistic treatment approach, including support and emotional coping strategies, should be recommended. In this article, diagnostic procedures and treatment options for excessive hair growth in female patients are discussed.

Severe hyperandrogenemia and insulin resistance in a 12-year-old girl

BACKGROUND

Signs of androgen excess are common complaints of adolescents and young adults. Rapid onset/progression of hyperandrogenism or virilization should prompt further investigation to exclude an androgen-secreting tumor.

CASE

We report the case of an obese young adolescent girl who presented with hirsutism, deepened voice, oligomenorrhea, marked acanthosis nigricans, and rapidly increasing testosterone and insulin levels. Imaging studies were negative for both ovarian and adrenal masses. She was successfully treated with continuous combined oral contraceptives. Investigation, treatment, and outcome are reviewed.

SUMMARY AND CONCLUSION

This case demonstrates that patients with PCOS may present with a testosterone > 200 ng/dL and that severe hyperinsulinemia can be associated with rapid progression of hyperandrogenism.

Hyperandrogenism sensitizes mononuclear cells to promote glucose-induced inflammation in lean reproductive-age women

Hyperandrogenism and chronic low-grade inflammation are related in polycystic ovary syndrome (PCOS), but it is unknown whether hyperandrogenemia can activate inflammation. We determined the effect of oral androgen administration on fasting and glucose-stimulated nuclear factor-κB (NF-κB) activation and expression and related markers of inflammation in mononuclear cells (MNC) of lean reproductive-age women. Sixteen lean, ovulatory reproductive-age women were treated with 130 mg of DHEA or placebo (n = 8 each) for 5 days in a randomized, controlled, double-blind fashion. Nuclear activation of NF-κB, p65 and p105 NF-κB subunit RNA, TNFα and IL-1β mRNA, and NF-κB p65 and inhibitory-κB (IκB) protein were quantified from MNC obtained while fasting and 2 h after glucose ingestion, before and after DHEA or placebo administration. Before treatment, subjects receiving DHEA or placebo exhibited no differences in androgens or any inflammatory markers while fasting and after glucose ingestion. Compared with placebo, DHEA administration raised levels of testosterone, androstenedione, and DHEA-S, increased the percent change in fasting and glucose-challenged activated NF-κB, p65, p105, TNFα, and IL-1β RNA and p65 protein, and decreased the percent change in fasting and glucose-challenged IκB protein. We conclude that elevation of circulating androgens to the range observed in PCOS upregulates the NF-κB inflammation pathway in lean reproductive-age women. Thus, hyperandrogenemia activates and sensitizes MNC to glucose in this population.

How should postmenopausal androgen excess be evaluated?

Evidence of clinical and/or biochemical androgen excess connotes a unique differential diagnosis in postmenopausal women. Providers need to be able to discriminate between changes of the normal ageing process compared to potential pathology in older women. The evaluation and treatment of postmenopausal hirsutism and hyperandrogenism is reviewed. Androgen excess may have long-term negative health consequences and as such should be detected and treated.

A premenopausal woman with virilization secondary to an ovarian Leydig cell tumor

BACKGROUND

A 33-year-old woman presented to an endocrinology clinic with a 5-year history of secondary amenorrhea. 2 years before presentation, she had noticed progressively worsening signs of virilization.

INVESTIGATIONS

Measurement of levels of serum free and total testosterone, androstenedione, dehydroepiandrosterone sulfate and gonadotropins; transvaginal ultrasonography, abdominal and pelvic MRI and (18)F-fluorodeoxyglucose PET imaging.

DIAGNOSIS

Virilization secondary to an ovarian Leydig cell tumor.

MANAGEMENT

The patient underwent a left salpingo-oophorectomy that confirmed the diagnosis of a unilateral Leydig cell tumor. Complete normalization of androgens and gonadotropin levels was achieved after surgery.

Androgen- and estrogen-secreting adrenal cancers

Androgen-secreting adrenal cancers are extremely rare malignancies, accounting for only a tiny proportion of the total number of women presenting with signs of androgen excess. Estrogen-secreting adrenal cancers are rarer still. Understanding how these tumors work benefits from an appreciation of adrenal steroid biosynthesis, as it is said that secretion in cancers is an anarchic version of normal adrenal function. Selection of patients in whom we should have a high suspicion of a malignancy is vital, so that biochemical investigation and imaging is deployed appropriately. When an adrenal tumor is found to secrete androgens or estrogens to excess, it can be difficult to confirm that it is a cancer, as there is significant overlap in the secretory patterns and imaging appearances of benign and malignant disease. The most reliable indicator of malignancy in these tumors remains the presence of metastases. Treatment is essentially surgical, although the role of mitotane is one undergoing evaluation.

Polycystic ovary syndrome (PCOS)

1. The Rotterdam classification should be used to define PCOS in the event of: menstrual cycle anomalies; amenorrhoea, oligomenorrhoea or long cycles, clinical and/or biochemical hyperandrogenism and ultrasound appearance of polycystic ovaries. 2. The presence of two of these three criteria is sufficient once all other diagnoses have been ruled out. 3. Diagnosis of hirsutism should not be based on the Ferriman-Gallway score. 4. The ultrasound definition of PCOS contains precise criteria that must be included in the report: presence of at least 12 follicles in each ovary measuring 2-9 mm in diameter, and/or increase in ovary size>10 ml. 5. Screening for elevated plasma LH no longer necessary. Testing for GnRH serves no purpose. 6. Routine screening for metabolic abnormalities should be carried out systematically based on weight, height and BMI, waist circumference, blood pressure and laboratory parameters: plasma glucose, triglycerides, HDL cholesterol. 7. In the case of obesity (BMI>30 kg/m(2)), oral glucose tolerance testing (OGTT) is recommended where fasting serum glucose is normal. 8. Clomiphene citrate (CC) remains the first-line therapy for ovulation induction. In patients with BMI>30, it should be preceded by improvement of metabolic status through appropriate lifestyle modifications.

Virilizing luteinized thecoma of the ovary in a 15-year-old female: a case report

BACKGROUND

Only 30% of luteinized thecomas are found in women under the age of 30, and they are typically benign. Only 11% of luteinized thecomas show clinical signs of androgen production. We present an unusual case of a 15-year-old female who presented with secondary amenorrhea and virilization and was subsequently diagnosed with a benign luteinized thecoma of the ovary. This is the youngest nonmalignant luteinized thecoma reported to date.

CASE

A 15-year-old Sri Lankan female presented with increasing hair growth, a hoarse voice, and secondary amenorrhea. On physical examination, there was marked hirsutism and clitoromegaly. Investigations found an elevated free testosterone level and an enlarged, homogenous left ovary with absent normal ovarian architecture. A laparotomy and unilateral salpingo-oophorectomy was performed. The final diagnosis was a luteinized ovarian thecoma, with no evidence of malignancy. Postoperatively, testosterone levels normalized and menstrual cycles resumed. Although laser treatment helped with her hirsutism, her other virilizing symptoms (deepening of voice, clitoromegaly) did not improve postoperatively.

CONCLUSION

This case of a virilizing ovarian luteinized thecoma emphasizes the need for timely evaluation, diagnosis, and treatment of patients presenting with symptoms of excess androgen secretion in order to avoid irreversible unwanted effects. Possible ovarian causes of excess androgen secretion should not be overlooked when considering possible causes of hyperandrogenism and secondary amenorrhea.

Hyperandrogenism due to a testosterone-secreting Sertoli-Leydig cell tumor associated with a dehydroepiandrosterone sulfate-secreting adrenal adenoma in a postmenopausal woman: case presentation and review of literature

OBJECTIVE

To report a case of hyperandrogenism attributable to the presence of an adrenal adenoma secreting dehydroepiandrosterone sulfate (DHEA-S) and an ovarian Sertoli-Leydig cell tumor secreting testosterone in a postmenopausal woman.

METHODS

The laboratory, radiologic, and pathologic findings in our case are described. In addition, the pertinent literature is reviewed.

RESULTS

A 56-year-old woman presented with a history of gradual increase in facial and body hair, scalp hair loss, male pattern baldness, and deepening of her voice, beginning a few years after spontaneous menopause at age 49 years. She had hypertension, obesity, and type 2 diabetes mellitus. Laboratory tests showed elevated levels of total testosterone (348 ng/dL) and DHEA-S (2,058 microg/dL), and a left adrenal tumor (3 by 4 cm) was detected on abdominal computed tomographic scan. Laparoscopic left adrenalectomy was performed, and the pathologic diagnosis was adrenal adenoma. The DHEA-S returned to normal levels, but the serum testosterone concentration remained elevated. Transvaginal ultrasonography disclosed an ovarian tumor. Bilateral oophorectomy was performed, and an ovarian Sertoli-Leydig cell tumor was diagnosed. The hormonal and clinical picture normalized after this surgical intervention.

CONCLUSION

After extensive review of the literature, we believe that this is the first reported case of a coincidental DHEA-S-secreting adrenal adenoma and a testosterone- secreting ovarian Leydig cell tumor causing signs of virilization.

The Androgen Excess and PCOS Society criteria for the polycystic ovary syndrome: the complete task force report

OBJECTIVE

To review all available data and recommend a definition for polycystic ovary syndrome (PCOS) based on published peer-reviewed data, whether already in use or not, to guide clinical diagnosis and future research.

DESIGN

Literature review and expert consensus.

SETTING

Professional society.

PATIENTS

None.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

A systematic review of the published peer-reviewed medical literature, by querying MEDLINE databases, to identify studies evaluating the epidemiology or phenotypic aspects of PCOS.

RESULT(S)

The Task Force drafted the initial report, following a consensus process via electronic communication, which was then reviewed and critiqued by the Androgen Excess and PCOS (AE-PCOS) Society AE-PCOS Board of Directors. No section was finalized until all members were satisfied with the contents, and minority opinions noted. Statements were not included that were not supported by peer-reviewed evidence.

CONCLUSION(S)

Based on the available data, it is the view of the AE-PCOS Society Task Force that PCOS should be defined by the presence of hyperandrogenism (clinical and/or biochemical), ovarian dysfunction (oligo-anovulation and/or polycystic ovaries), and the exclusion of related disorders. However, a minority considered the possibility that there may be forms of PCOS without overt evidence of hyperandrogenism, but recognized that more data are required before validating this supposition. Finally, the Task Force recognized and fully expects that the definition of this syndrome will evolve over time to incorporate new research findings.

Helpful diagnostic markers of steroidogenesis for defining hyperandrogenemia in hirsute women

HYPOTHESIS

Androgen excess carries varied clinical manifestations in women. Although testosterone and dehydroepiandrostendionesulfate (DHEAS) determination is considered useful in diagnostic workup, there is no laboratory definition that sufficiently describes androgen excess.

DESIGN

We studied 464 hirsute women with a Ferriman and Gallwey score of at least 8 between 2000 and 2005. Our examination included clinical data, total testosterone (T), sex hormone-binding globulin (SHBG), the free androgen index (FAI), and DHEAS. Additionally, androstendione, 17alpha-hydroxyprogesterone (17OHP), dehydroepiandrostendione (DHEA), and 11-deoxycortisol were determined at baseline and 60min after corticotropin challenge (250microg synacthen).

RESULTS

Of 464 women, 77.6% fulfilled the clinical criteria for hyperandrogenemia. Of these 360 women, 78.1% had hyperandrogenic hirsutism. Of these 281 women, 43.4% showed increased stimulation of 17OHP to 250microg of synacthen. Another 37.4% showed adrenal steroid biosynthesis defects other than 21alpha-hydroxylase deficiency, such as defective 11beta-hydroxylation or 3beta-hydroxysteroid dehydrogenase malfunction. The diagnosis of polycystic ovary syndrome was applicable to 12.4%. In addition, our results show that 72% of 281 patients with secondary hirsutism had normal T concentrations, and 55% had a normal FAI. Only 5% of hirsute patients with a normal FAI had elevated DHEAS values. However, 40% showed elevated DHEA levels, while 26% of the women with normal FAI showed androstendione values over the maximal levels in the 79 controls.

CONCLUSIONS

Our data suggest that in addition to testosterone and FAI, androstendione and DHEA are significantly helpful parameters in diagnosing hyperandrogenemia in hirsute women. DHEAS was not found to be helpful.

Virilization caused by an ectopic adrenal tumor located behind the iliopsoas muscle

OBJECTIVE

Virilization due to androgen-secreting neoplasms in women is a result of androgen overproduction from benign or malignant tumors that are found in the ovaries or rarely in the adrenal glands. Virilizing tumors that arise from ectopic adrenal tissue are extremely rare. We describe a very rare case of an ectopic androgen-producing adrenal tumor.

DESIGN

Case report study.

SETTING

Endocrinology outpatient department of university-affiliated teaching hospital.

PATIENT(S)

A 45-year-old woman with symptoms of virilization of abrupt onset and rapid progression, with high serum androgen hormone levels and normal glucocorticoid secretion.

INTERVENTION(S)

Basal hormonal levels, stimulation and suppression tests, imaging techniques, and selective venous sampling.

MAIN OUTCOME MEASURE(S)

Localization and surgical removal of the source of androgen production.

RESULT(S)

An ectopic mass was detected behind the left iliopsoas muscle. The patient was operated on and an oblong-shaped lesion, weighing 6 g, was removed. Histologically, the tissue was identified to be of adrenal origin. Postoperatively the androgen levels decreased to normal levels.

CONCLUSION(S)

This case illustrates difficulties in detecting and localizing the rare contingence of an ectopic adrenocortical androgen-secreting tumor.

Performance Characteristics of a Novel Tandem Mass Spectrometry Assay For Serum Testosterone

Background: Commercial immunoassays for testosterone (Te) may give inaccurate results for samples from women and children, leading to misdiagnosis and inappropriate treatment. We developed a sensitive and specific tandem mass spectrometric assay for measurement of Te at the concentrations encountered in women and children.

Methods: Te was extracted with methyl tert-butyl ether from 100 μL of serum or plasma, derivatized to form an oxime, and reextracted by solid-phase extraction. Instrumental analysis was performed on an API 4000 HPLC tandem mass spectrometer in the multiple-reaction monitoring (MRM) mode. The MRM transitions (m/z) were 304→124 and 304→112 for Te and 307→124 and 307→112 for d3-Te.

Results: Within- and between-run CVs were <12% and 7.9%, respectively. The limit of quantification was 0.0346 nmol/L (1 ng/dL). Reference intervals for sex hormone–binding globulin and total, free, and bioavailable Te were established for children of Tanner stages 1 through 5 and adult males and females.

Conclusions: The sensitivity and specificity of the method are adequate for analysis of Te in samples from women and children. The method requires small sample volumes, has adequate precision, and is not subject to interferences.

SETTING

Academic tertiary-care medical center.

PATIENT(S)

Three hundred forty women with hirsutism as the referral diagnosis.

INTERVENTION(S)

Hormone analyses and ACTH tests during cycle days 2-8, 2 hours of oral glucose tolerance test (OGTT), and vaginal ultrasound.

MAIN OUTCOME MEASURE(S)

End diagnosis, fasting, 30-, 60-, and 120-minute oral glucose-stimulated levels of insulin and capillary blood glucose.

RESULT(S)

Two hundred one patients were diagnosed as having idiopathic hirsutism (IH) and 134 as having polycystic ovary syndrome (PCOS). End diagnosis: prolactinoma: n = 1, Cushing's syndrome: n = 1, androgen-producing ovarian tumor: n = 1, late-onset 21-hydroxylase defects: n = 2. During OGTT, 4.9% (13 of 263) had previously undiagnosed diabetes; no significant difference in diabetes prevalence was found between idiopathic hirsutism and PCOS. For 50.8%, fasting insulin values were in the upper quartile for a reference population.

CONCLUSION(S)

Initial evaluation of hirsute patients with irregular menses should include serum (s)-17alpha-hydroxyprogesterone, s-prolactin, s-Testosterone (T), and s-sex hormone-binding globulin. Further evaluation is needed in patients with markedly elevated s-T or with clinical Cushing's syndrome. Hirsute patients have a high risk of diabetes, although this could be due to the high number of overweight patients among this population.

Hirsutism and acne in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the most common endocrine abnormality affecting reproductive age women. Population-based studies estimate a prevalence of 5-10% [Obstet Gynecol 101 (2003) 995; Aust N Z J Obstet Gynaecol 41 (2001) 202]. The clinical characteristics of PCOS include hyperandrogenism, chronic anovulation, insulin resistance and infertility. Hyperandrogenism is generally manifested as hirsutism and acne. Both these clinical symptoms are treated with similar drug therapies, including oral contraceptive pills (OCPs), topical medications or antiandrogens such as spironolactone, flutamide and finasteride, as well as topical medications. Recent studies have shown that lower doses of these medications are as efficacious as high doses and have the advantage of decreased cost and an improved side-effect profile. Although hirsutism and acne can be considered cosmetic in nature, they cause significant social embarrassment and emotional distress. Physicians should be sensitive to these issues and approach patients in a caring and sympathetic manner.

Revised 2003 consensus on diagnostic criteria and long-term health risks related to polycystic ovary syndrome

Since the 1990 National Institutes of Health-sponsored conference on polycystic ovary syndrome (PCOS), it has become appreciated that the syndrome encompasses a broader spectrum of signs and symptoms of ovarian dysfunction than those defined by the original diagnostic criteria. The 2003 Rotterdam consensus workshop concluded that PCOS is a syndrome of ovarian dysfunction along with the cardinal features hyperandrogenism and polycystic ovary (PCO) morphology. PCOS remains a syndrome, and as such no single diagnostic criterion (such as hyperandrogenism or PCO) is sufficient for clinical diagnosis. Its clinical manifestations may include menstrual irregularities, signs of androgen excess, and obesity. Insulin resistance and elevated serum LH levels are also common features in PCOS. PCOS is associated with an increased risk of type 2 diabetes and cardiovascular events.

Is ovarian and adrenal venous catheterization and sampling helpful in the investigation of hyperandrogenic women?

OBJECTIVE

To audit our practice of performing ovarian and adrenal venous catheterization and sampling in hyperandrogenic women who fail to suppress their elevated androgen levels following a 48-h low-dose dexamethasone suppression test (LDDST). We considered the technical success rate of catheterization, the extra information obtained in addition to the standard biochemical tests and imaging findings, and the impact of sampling on management decisions.

DESIGN

A retrospective analysis of the results of all ovarian and adrenal venous catheterizations performed at St Bartholomew's Hospital, London, in the years 1980-1996.

PATIENTS AND METHODS

Baseline ovarian and adrenal androgens were measured in all women presenting with symptoms and signs of hyperandrogenism. Those patients who failed to suppress their elevated testosterone (T), androstenedione (A4) and/or dehydroepiandrosterone-sulphate (DHEAS) levels following a LDDST to within the normal range or to less than 50% of the baseline value were investigated further with adrenal computed tomography (CT), ovarian ultrasound, and ovarian and adrenal venous catheterization and sampling.

RESULTS

Results were available in 38 patients. The overall catheterization success rate was: all four veins in 27%, three veins in 65%, two veins in 87%. The success rate for each individual vein was: right adrenal vein (RAV) 50%, right ovarian vein (ROV) 42%, left adrenal vein (LAV) 87% and left ovarian vein (LOV) 73%. Eight patients were found to have tumours by means of imaging (adrenal CT and ovarian ultrasound), three adrenal and five ovarian, seven of which underwent operation. In six of these patients the clinical presentation was suggestive of the presence of a tumour; in addition, the combination of imaging findings allowed the detection of suspicious adrenal and ovarian masses in all eight cases. The five patients with ovarian tumours had serum testosterone levels > 4.5 nmol/l. In a further eight patients, laparotomy was performed based on a combination of diagnostic and therapeutic indications; in two of these patients the catheterization results were suggestive of an ovarian tumour. All these eight patients were shown histologically to have polycystic ovarian syndrome (PCOS), and no occult ovarian tumour was identified. None of the patients with nontumourous hyperandrogenism had a baseline testosterone level in excess of 7 nmol/l (median 4.4 nmol/l, range 2.5-7 nmol/l).

CONCLUSIONS

Our results suggest that ovarian and adrenal venous catheterization and sampling should not be performed routinely in women presenting with symptoms and signs of hyperandrogenism, even if they fail to suppress their elevated androgen levels to a formal 48-h LDDST. All patients presenting with symptoms and signs of hyperandrogenism and elevated androgen levels, and where the suspicion of an androgen-secreting tumour is high, should have adrenal CT and ovarian ultrasound imaging to detect such a tumour. Venous catheterization and sampling should be reserved for patients in whom uncertainty remains, as the presence of a small ovarian tumour cannot be excluded on biochemical and imaging studies used in this series alone. Its use should be restricted to units with expertise in this area.

The value of the low-dose dexamethasone suppression test in the differential diagnosis of hyperandrogenism in women

We studied 211 hyperandrogenic women with respect to clinical presentation, basal androgen levels, and the degree of cortisol and androgen suppression during a 48-h low-dose (2 mg) dexamethasone-suppression test (LDDST) to exclude ovarian and adrenal tumors. In 42 women with elevated testosterone levels, 21 of whom failed to suppress testosterone during the LDDST, the response of serum androgen levels during a 4-wk administration of 7.5 mg prednisolone in a reverse circadian regimen was also assessed. These results were compared with an additional 17 patients with histologically proven androgen-secreting tumors. Clinical presentation alone was suggestive of a virilizing tumor in 70% of patients with tumors. Serum testosterone, although occasionally only marginally elevated, was the sole androgen that was elevated in every patient with a tumor. After the LDDST, none of the patients with tumors obtained either a greater than 40% reduction or normalization of the previously elevated testosterone levels, whereas 88% of patients with nontumorous hyperandrogenism showed either normalization or suppression of more than 40%. With one exception, all of the patients with nontumorous hyperandrogenism who showed inadequate suppression of testosterone during the LDDST, and were treated with prednisolone, normalized the previously elevated androgens after 1 month of administration. In summary, in women presenting with hyperandrogenism, lack of testosterone suppression during the LDDST is associated with 100% sensitivity and 88% specificity in distinguishing patients with ovarian and adrenal androgen-secreting tumors from patients with nontumorous hyperandrogenism in this small series. The LDDST is an easy to perform screening test that can also identify causes of hyperandrogenism due to altered glucocorticoid secretion.

Acne: effect of hormones on pathogenesis and management

In the pathogenesis of acne, androgen hormones play a crucial role. In the treatment of acne, hormonal therapies provide valuable alternatives to standard modalities in selected women. Although numerous factors contribute to the development of acne, the requirement for androgens is absolute and is one that allows for effective treatments in women through inhibition of androgen expression. The two prerequisites for androgen expression at the level of the pilosebaceous unit are the presence of androgen in the form of either testosterone or dihydrotestosterone; and functioning androgen receptors. A third component may be the metabolism of androgen precursors to active androgens within pilosebaceous units. Hormonal treatment of hyperandrogenism (acne, hirsutism, androgenetic alopecia) such as that seen in polycystic ovary syndrome, centers on reduction of circulating androgen levels and androgen receptor blockade. Combination oral contraceptives represent the primary treatment modality for reducing circulating androgens from ovarian and, to a lesser degree, adrenal sources. Newer formulations may also have clinically significant androgen receptor blocking and 5alpha-reductase inhibiting effects. Newer oral contraceptives have high safety profiles and are used widely internationally for this purpose. Androgen receptor blockers currently in use include spironolactone, cyproterone acetate, and flutamide. Androgen receptor blockers are frequently combined with oral contraceptives to achieve optimal results in selected women. In women with adrenal hyperplasia, low-dose corticosteroids may be added to reduce adrenal androgen precursors. Inhibition of enzymes of androgen metabolism in the pilosebaceous unit remain largely investigational in the treatment of acne, although the benefit of 5alpha-reductase (type 2) inhibition is established in androgenetic alopecia in men. This article reviews the essentials of hormonal influence in acne pathogenesis, discusses the hormonal therapies most utilized in the treatment of acne, and the pre-treatment evaluation of women in whom hormonal therapies are being considered.

Polycystic ovary syndrome. A diagnostic challenge

Polycystic ovary syndrome remains a diagnostic challenge because there is no single defining test. The clinical presentation must dictate the extent of the work-up. The typical PCOS patient has a history of irregular menses and appears hirsute. Demonstration of ovulatory dysfunction and hyperandrogenism can also be made by appropriate hormonal measurements. An ultrasound showing multiple small ovarian follicles can support a diagnosis of PCOS in the patient for whom the clinical diagnosis has been made. Other causes of hyperandrogenism and ovulatory dysfunction should be excluded.
