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

ObjectiveTo 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.MethodsThe laboratory, radiologic, and pathologic findings in our case are described. In addition, the pertinent literature is reviewed.ResultsA 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 μg/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.ConclusionAfter 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.

Ovarian Hilus-Cell Hyperplasia and High Serum Testosterone in a Patient With Postmenopausal Virilization

ObjectiveTo describe a woman with postmenopausal virilization and hirsutism caused by hilus-cell hyperplasia.MethodsWe present a case report including laboratory, radiographic, and pathologic findings in a patient with postmenopausal hirsutism and virilization caused by ovarian hilus-cell hyperplasia as well as a brief review of the literature.ResultsA 60-year-old postmenopausal woman presented with extensive hirsutism, male-pattern hair loss, and clitoromegaly. The patient’s plasma testosterone levels were very high, but computed tomography showed the adrenal glands to be normal in size. Pelvic ultrasonography revealed a cystic lesion in the left ovary. After bilateral salpingo-oophorectomy, histologic examination demonstrated a diffuse pattern of hilus-cell hyperplasia in the ovarian hilum.ConclusionIn the differential diagnosis of postmenopausal virilization, hilus-cell hyperplasia, although rare, should be considered.     

Hyperandrogenism in a Postmenopausal Woman: Diagnostic and Therapeutic Challenges

ObjectiveTo describe a postmenopausal woman with severe hyperandrogenism who responded dramatically to a gonadotropin-releasing hormone (GnRH) agonist.MethodsDetailed clinical and laboratory findings are presented, and the pertinent literature is reviewed.ResultsA 53-year-old postmenopausal woman with end-stage renal disease, who had undergone kidney transplantation, was referred because of high serum testosterone levels. She presented with worsening acne and hirsutism for the previous 2 years. Her medications included prednisone (7.5 mg every other day). On examination, mild facial acne and hirsutism but no virilizing features were noted. Laboratory results showed generous postmenopausal gonadotropin levels and markedly elevated total and free testosterone levels, which failed to suppress with a 2-day low-dose dexamethasone test. Transvaginal ultrasonography and a computed tomographic scan failed to identify an ovarian or adrenal abnormality. Administration of a GnRH agonist (Depo-Lupron) resulted in a dramatic decline in follicle-stimulating hormone, luteinizing hormone, and testosterone levels after 1 month, which persisted during the course of 11 months of therapy. The source of marked hyperandrogenism in postmenopausal women represents a diagnostic challenge. The absence of a tumor on diagnostic imaging and the inability to perform catheterization studies confound the problem. Androgen levels did not suppress with glucocorticoids. We reasoned that a clear response to a GnRH agonist would indicate a nontumorous ovarian source of hyperandrogenism. Regrettably, the literature has described cases of ovarian tumors and, rarely, adrenal adenomas that are responsive to gonadotropins.ConclusionThe striking improvement in a postmenopausal woman with severe hyperandrogenism by means of GnRH agonist therapy demonstrates its potential use in poor surgical candidates without necessarily delineating the source of androgen excess.

Virilizing Ovarian Leydig Cell Tumor in A Woman with Subclinical Cushing Syndrome

ObjectiveTo report the case of a patient with a virilizing ovarian Leydig cell tumor and subclinical Cushing syndrome attributable to an adrenal adenoma.MethodsDetailed clinical, laboratory, radiologic, and pathologic findings are presented, and the pertinent literature is reviewed.ResultsA 49-year-old woman was referred for evaluation of a left adrenal mass (3.0 by 2.4 cm), which had been diagnosed by computed tomographic scan 4 years previously during a work-up for hirsutism. On examination, she had central obesity, facial hirsutism, and male pattern baldness. Work-up showed elevated total and free testosterone levels of 196 ng/dL (reference range, 20 to 70) and 24 pg/mL (1 to 9), respectively. Other results (and reference ranges) were as follows: dehydroepiandrosterone sulfate, 7.5 μg/dL (10 to 221); corticotropin, 12 pg/mL (5 to 50); morning cortisol, 1.4 μg/dL after a 1-mg overnight dexamethasone suppression test; and urine free cortisol, 48.8 μg/24 h (20 to 100). The testosterone level decreased by 14% after a 2-day low-dose dexamethasone suppression test. Findings on transvaginal ovarian ultrasonography and a computed tomographic scan of the pelvis were normal. A laparoscopic adrenalectomy revealed an adrenal adenoma. On the first day postoperatively, the cortisol level was less than 1.0 μg/dL; however, the testosterone level remained elevated. At 6 months postoperatively, a normal result of a cosyntropin stimulation test indicated recovery of the hypothalamic-pituitaryadrenal axis. Bilateral oophorectomy revealed a 1.3-cm right ovarian Leydig cell tumor. Postoperatively, the testosterone level declined to less than 20 ng/dL.ConclusionTo our knowledge, this is the first case report of a virilizing ovarian Leydig cell tumor in a patient with subclinical Cushing syndrome.

Testosterone-secreting adrenocortical tumor in a pubertal girl. Case report and review of the literature

A girl aged 12 years and 10 months presented with deepening of the voice first noted 7 months earlier. Pubertal development was almost completed. The girl had regular monthly menses and no signs of hirsutism, clitoris enlargement or Cushing's disease. Serum testosterone was about threefold above normal, whereas dehydroepiandrosterone was in the upper normal range. The 17-ketosteroids as well as the gas-chromatographically analyzed 5 alpha and 5 beta derivatives of testosterone from urine were slightly increased. Other serum and urinary steroids were normal. Dynamic tests of the endocrine function exhibited inconclusive results. Ultrasonography revealed no ovarian cysts. A small, left-sided adrenal mass was identified by computed axial tomographic scan and removed by surgery. There were no signs of local metastasis nor of vascular extension. The histopathological diagnosis was adrenocortical carcinoma. 5 months after surgery, the preoperatively elevated steroid levels had returned to normal.     

Menstrual disorders in adolescence: pathophysiology and treatment.

Menstrual problems including amenorrhea, oligomenorrhea, irregular cycles, abnormal uterine bleeding or dysmenorrhea represent 50% of adolescents' gynecologic complaints. Irregular and anovulatory cycles are common during the first postmenarcheal years and may reflect a normal transient step of ovarian hyperandrogenism, but they may also result from hormonal abnormalities affecting the adrenals, the ovaries or the pituitary. Amenorrhea may be a sign of late puberty or of a problem affecting the hypothalamus, the pituitary or the ovaries. Evaluation includes a complete physical examination, basal hormonal determinations of the hypothalamic-pituitary-ovarian function, of the thyroid, of the androgens and of the nutritional and growth parameters. This first evaluation must be completed by a karyotype analysis in case of primary amenorrhea or by the measurements of free testosterone, androstanediol glucuronide and testosterone glucuronide in case of hirsutism, and may be followed by X-rays, echography or dynamic tests depending on the first results. Therapy will always be directed towards the etiology of the disease. Abnormal uterine bleeding is generally the result of anovulatory cycles and responds to hormonal therapy, but a systemic illness, a local pathology or a complicated pregnancy must always be excluded. In case of dysmenorrhea, endometriosis must be excluded. Simple dysmenorrhea is generally suppressed by antiprostaglandins.     

Cytologic features of ovarian granulosa cell tumor metastatic to the lung. A case report

BACKGROUND: Granulosa cell tumor (GCT) of the ovary is an uncommon but not rare tumor, and the adult type usually affects postmenopausal women. The adult type of GCT has several characteristic clinicopathologic features, including a composition of small, uniform cells with Call-Exner bodies and an ability to metastasize to extrapelvic organs, even several decades after the initial operation. CASE: A 62-year-old female was incidentally found to have multiple shadows in the peripheral portions of both lung fields on roentgenography. She had a past history of oophorectomy for an ovarian carcinoma more than 20 years earlier. A transbronchial lung biopsy series was nondiagnostic. An aspirate obtained by transthoracic fine needle aspiration (FNA) biopsy revealed clusters of rather uniform, small cells with nuclear grooves, suggestive of a metastatic lung tumor. Histologic examination of the lung tissue in comparison with the previous oophorectomy specimen confirmed the impression of GCT metastatic to the lung. CONCLUSION: A preoperative diagnosis of metastatic lung tumor was established by transthoracic FNA cytology. The important cytologic criteria for the differential diagnosis are uniformity of tumor cells, coffee bean-like nuclear grooves and Call-Exner bodies. The possibility of late recurrence of this kind of tumor, even two or three decades after surgical resection, should be kept in mind.     

Fine needle aspiration cytology of a recurrent juvenile granulosa cell tumor

Fine needle aspiration biopsy was performed on a recurrent juvenile granulosa cell tumor of the ovary in a 24-year-old woman. The cytologic appearances and the results of histochemical, immunocytochemical and ultrastructural studies are described, and the differential diagnosis with other ovarian tumors is discussed.     

Concomitant sertoli and leydig cell tumor of the testis: a case report

A rare intratubular gonadal stromal tumor was present in the testis of a 45-year-old man who was admitted to our hospital with the chief complaint of gradual enlargement of the left testis. Tumoral markers were negative and no extension was observed. The tumor comprised an intratubular mixture of two types of tumor cells with intercellular junctions: the predominant tumor cells were consistent with a Sertoli cell origin and cells comprising the minor population consistent with a Leydig cell origin. The patient is disease free after 6-month follow-up. The case is considered to be a testicular mixed tubular Sertoli-Leydig cell tumor. It highlights a rare type of primary tumor of the testis that features a good prognosis.     

Exploration of hirsutism: elements for a strategy

50 women complaining of hirsutism were investigated in order to establish an optimal strategy for hirsutism exploration. Basal hormonal evaluations were of great value, especially serum testosterone and, to a lesser degree, DHA-S and LH. LH response to LHRH stimulation appeared of little diagnostic value. ACTH stimulation tests may be useful in detecting enzyme deficiencies in patients with normal basal values. The origin of hyperandrogenism can hardly be detected by the inhibition tests. However, these tests allow to determine whether the androgen secretion is still under ACTH and/or LH control.     

A case study of virilizing adrenal tumor in an adolescent female elite tennis player--insight into the use of anabolic steroids in young athletes

A 14-year-old Caucasian girl was referred to the endocrine clinic for evaluation of voice deepening, facial hirsutism, and acne starting 2 years previously. She had been a competitive tennis player since age 7 years, practicing for 4-6 hours daily. On physical examination she was noticed to have a masculine appearance with mild facial acne and moderate hirsutism. Tanner stage was 1 for breast tissue and 5 for pubic hair. Her androgen levels (testosterone, androstenedione, dehydroepiandrosterone sulfate) were extremely elevated. Adrenal ultrasonography revealed a round left 4.6 × 5.3-cm adrenal mass. Laparoscopic left adrenalectomy was performed. The histologic findings were compatible with a benign adrenocortical tumor. Postoperatively, androgen levels dropped to within the normal range. Breast development proceeded normally, menarche occurred 2 months after tumor resection, and menses has been regular since then. Muscle strength of the dominant and nondominant upper and lower extremities was measured 1 month before surgery and 1 year later, using an isokinetic dynamometer (Biodex Systems II, Biodex, Shirley, NY, USA). There was no significant decrease in overall muscle strength after removal of the virilizing tumor and the marked drop in circulating androgens. In addition, the patient maintained her age category, number 1, national tennis ranking. The results suggest that even extremely high levels of tumor-related circulating androgens had no evident effect on muscle strength and competitive performance in a female adolescent tennis player. The lack of beneficial effect on performance in adolescents, combined with the potentially hazardous side effects of anabolic steroids, suggests that teenage athletes should avoid their use.     

Hormone concentrations in the homogenates of ovarian tissue and blood serum in postmenopausal women not using hormone therapy

Ovaries in postmenopausal women synthesize steroids, mostly androgens. Removal of the ovaries after menopause may be reflected by menopausal symptoms and arterial hypertension observed during postoperative period, along with a significantly increased risk of death due to cardiovascular complications. It is not understood if the clinical consequences of gonad removal at different time points after menopause are similar. The aim of this study was to evaluate ovarian steroidogenesis and consequently to define the role of the ovaries in postmenopausal women depending on the time after menopause. Concentrations of hormones were determined in ovarian homogenates and serum of postmenopausal women. This study included 207 postmenopausal women. They were divided into groups depending on the time after menopause. All participants had laparotomic removal of the ovaries. Concentrations of estradiol, testosterone and androstenedione were measured in ovarian homogenate and serum. The study revealed that ovarian homogenate and serum concentrations of estradiol, testosterone and androstenedione were the highest in women up to 5 years after menopause and since then significantly decreased. This study showed that testosterone, androstenedione and estradiol are synthesized in the postmenopausal ovaries. The peak synthesis of these hormones occurs up to 5 years after menopause and significantly decreases thereafter.     

Efficacy of porcine gonadotropins for repeated stimulation of ovarian activity for oocyte retrieval and in vitro embryo production and cryopreservation in Siberian tigers (Panthera tigris altaica)

A comparison of the amino acid sequences demonstrated that Siberian tiger gonadotropins are more homologous with those of porcine than any other commercially available preparation. The present study measured the efficacy of repeated ovarian stimulation with purified porcine gonadotropins on the follicular, hormonal, and immunogenic responses in Siberian tigers as well as on the ability of oocytes retrieved by laparoscopic follicular aspiration to fertilize and cleave in vitro. Controlled rate and vitrification cryopreservation methods were also compared for their ability to support ongoing cleavage following thawing of presumptive 2- to 4-cell tiger embryos generated in vitro. Vitrification supported continued embryonic cleavage in vitro while controlled rate freezing did not. Stereological microscopy indicated an excellent ovarian response with the recovery of quality cumulus-oocyte complexes that apparently fertilized and cleaved in vitro. However, ultrastructural and physiological examination revealed abnormal and unnatural responses such as the failure of some cumulus-oocyte complexes to reach maturity and progestagen levels to approach normalcy. At the same time, analyses of blood for antibodies failed to detect an immune reaction to these foreign gonadotropins in an assay that tested positive for the chorionic gonadotropin-stimulated domestic cat. Together, these observations suggest that porcine gonadotropins may be effective for the ovarian stimulation of tigers but that some modifications to administration protocols are needed to produce a more natural response.     

Cytology of yolk-sac tumor of the ovary in ascitic fluid. Report of a case

The cytologic, serologic, immunocytochemical and histologic findings of a yolk-sac tumor of the ovary in which the diagnosis was suggested by the cytologic examination of ascitic fluid specimens are reported. The case emphasizes the importance of evaluating, in addition to smears, the cytologic findings of a cell block specimen (which is generally prepared from an effusion) to obtain more diagnostic clues. A preliminary cytomorphologic diagnosis of this highly malignant tumor is valuable as a guide in planning further immunocytochemical and serologic studies.     

Leydig cell tumor of the testis with azoospermia and elevated delta4 androstenedione: case report

Background

Secreting interstitial cell (Leydig cell) tumors are rare. In adults, the clinical picture and steroid levels are variable.

Case presentation

This paper presents a case of left testicular tumor, showing azoospermia with normal serum level of total testosterone, collapsed FSH and LH, and high delta4 androstenedione. Histopathological investigation revealed a Leydig cell tumor. TESE allowed spermatozoa extraction and freezing. Testicular histology found hypospermatogenesis and germ-cell aplasia with interstitial fibrosis. Surgical resection of the tumor resulted in normalization of gonadotropins and fall in serum delta4 androstenedione to subnormal levels in the postoperative period confirming that the tumor was secreting delta4 androstenedione. It was hypothesized that high delta4 androstenedione resulted in intra tumoral 17 β-HSD overtaken by delta4 androstenedione or that 17 β-HSD activity in the tumor was different from that of normal Leydig cells. Three months after surgery sperm analysis found a complete recovery of spermatogenesis. A spontaneous pregnancy occurred 3 months after surgery and a girl was born.

Conclusions

In this case, the diagnosis of testicular Leydig cell tumor secreting delta4 androstenedione was made in a context of azoospermia.

     

Management of hyperandrogenism in adolescent girls.

Hyperandrogenism in adolescent girls can be a troubling problem because of the difficulty in establishing a diagnosis and in prescribing appropriate therapy. Androgen excess in adolescent patients encompasses a spectrum of clinical presentations, including acne, hirsutism, oligomenorrhea, amenorrhea, virilism, and ovarian cysts. Androgen excess is a clinical and chemical feature of idiopathic hirsutism, late-onset forms of congenital adrenal hyperplasia, and polycystic ovarian disease; in some cases, functional hyperandrogenism is discussed. We recommend screening for hyperandrogenism by measuring blood levels of testosterone, dehydroepiandrosterone sulfate, and delta 4-androstenedione, while others propose a first dexamethasone suppression test for evaluation of free testosterone, dehydroepiandrosterone sulfate, and cortisol. Treatment will be chosen according to particular symptoms such as acne, hirsutism, obesity, or oligomenorrhea.     

Plasma androgens in idiopathic hirsutism

The plasma concentrations of testosterone, androstenedione,5-androstene-3β, 17β-diol, 5α-dihydrotestosterone and 17β-hydroxy-androgens have been measured in normal women and in patients with idiopathic hirsutism. The mean levels of all the compounds studied were higher in the group of patients with hirsutism than in the controls and apart from dihydrotestosterone, this difference was statistically significant. The correlation between the plasma levels of the various steroids was examined. In the normal subjects, testosterone and androstenedione levels were well correlated, but in the hirsute patients, the correlation is poor. It is suggested that this is related to altered binding of testosterone to plasma proteins in these patients. No one of the steroid levels measured was consistently abnormal in hirsutism, but in 40% of the patients, plasma androstenedione levels were above the normal range.     

An oestrogen-producing seminoma responsible for gynaecomastia.

In feminising testicular tumours, oestrogens can be either secreted by the tumour itself or produced by normal Leydig cells in response to paracrine and/or endocrine stimulation by hCG. Typical hormonal Leydig cell tumour patterns include: plasma oestradiol levels > 300 pmol/l on day 3 following an hCG injection, reduced plasma testosterone, and normal plasma hCG and gonadotrophin levels. Except for elevated plasma oestradiol levels, opposite results are observed in seminomas. We report a case of oestrogen-secreting seminoma mimicking a Leydig cell tumour. A 24-year-old Caucasian patient had complained of gynaecomastia for 6 months before admission. Hormonal pattern was typical of Leydig cell tumour. A 1.4 cm tumour was found in the left testis and confirmed on sonography. Considering the likely diagnosis of Leydig cell tumour, the patient was treated by tumourectomy. Surprisingly, pathological examination revealed a pure seminoma. Perifusion experiments showed that the tumour was able to secrete significant amounts of oestradiol. In addition, hCG induced a two-fold increase in oestradiol production from perifused tumour explants. Immunohistochemistry revealed that the tumour was composed of nests of seminoma cells intermingled with lymphoid infiltrates. Tumour cells also expressed aromatase, the hCG/LH receptor and the Leydig cell marker relaxin-like factor, but were betahCG-negative. These results demonstrate that a pure seminoma of the testis is able to synthesise and secrete oestrogens. They also illustrate that the body of proof favouring the diagnosis of feminising Leydig cell tumour of the testis is not rigorously specific.     

Inhibin B,follicle stimulating hormone,luteinizing hormone and testosterone during childhood and puberty in males: changes in serum concentrations in relation to age and stage of puberty

Inhibin B is a gonadal dimeric polypeptide hormone that regulates synthesis and secretion of follicle stimulating hormone (FSH) in a negative feedback loop. The aim of the present study was to determine changes in serum inhibin B, gonadotropins and testosterone concentrations during childhood and puberty in males. We studied the relationship between circulating inhibin B, gonadotropins and testosterone in serum of healthy boys during the first two years of life and then in pubertal development. Using a recently developed two-side enzyme-linked immunosorbent assay (ELISA), inhibin B levels were measured in the serum of 78 healthy boys divided into eleven age groups from birth to the end of pubertal development. In addition, serum levels of gonadotropins and testosterone were measured. Serum inhibin B, gonadotropins and testosterone increased during the first months of postnatal life. A peak in serum inhibin B and gonadotropins concentrations was observed around 3-4 months of age. There was a significant positive correlation between serum inhibin B and gonadotropins and testosterone levels during the first 2 years of life. After this early increase, serum inhibin B, gonadotropins and testosterone levels decreased significantly and remained low until puberty followed by an increase beginning with the onset of puberty. Serum levels of inhibin B reached a peak at stage G3 of puberty. Around midpuberty, inhibin B lost its positive correlation with luteinizing hormone (LH) and testosterone from early puberty, and developed a strong negative correlation with FSH, which persisted into adulthood. We conclude that inhibin B plays a key role in the regulation of the hypothalamic-pituitary-gonadal hormonal axis during male childhood and pubertal development. Inhibin B is a direct marker of the presence and function of Sertoli cells and appears to reflect testicular function in boys.     

Development of an experimental ovarian tumor over a year in the rat.

Tumor growth, possible malignant transformation or metastatic propagation and hormonal patterns were evaluated over a year in luteoma induced by introducing an ovary into the spleen of ovariectomized 60 day-old rats. Sham castrated animals had a piece of muscle inserted into the spleen. Jugular blood samples were taken monthly. After a year animals were cycled and decapitated. Troncal blood was collected, autopsies were performed and luteoma were measured and fixed in 10% buffered formalin. Serum LH, FSH, PRL, estradiol and progesterone were measured. Serum inhibin content was determined in one month-old tumors-bearing animals and estrous rats as controls. After one year no external changes in tumor-bearing rats were observed, nor differences in body weight or mortality rates compared to Sham animals. Metastatic propagation was absent. Routine histological examination showed two types of tumors according to either granulosa or luteal cell predomination, tumor type did not determine hormonal patterns. However, a clear relationship between gonadotropin levels and tumor size was established. Low gonadotropins: Small tumors, 18.7% of cases and high gonadotropins: Large tumors, 81.3%. In Sham animals gonadotropins attained castrate levels and remained elevated until the end of the experiment. In the Small group no increases in gonadotropins or estradiol were detected, progesterone and PRL fluctuated. In the Large tumor group LH increased to Sham titers until month 7, then fell to initial levels, FSH augmented significantly as from month three and remained high up to month 5. No variations in either estradiol, progesterone or PRL were observed. Serum inhibin of one month-old tumor-bearing rats was significantly elevated, justifying the lack of FSH increase at this time point. We conclude that these luteoma do not suffer malignant transformation or induce metastases. They appear in two histological types. Tumor size depends on hormonal patterns. The delay in the initial increase and the sharp decrease observed in FSH in animals bearing Large tumors suggest a possible role for inhibin in this regulation.
