Testosterone-secreting adrenal adenoma that contained crystalloids of Reinke in an adult female patient

A rare case of pure testosterone-secreting adrenal adenoma in a postmenopausal elderly woman

BACKGROUND

Hyperandrogenemia is more common in puberty and reproductive age, but relatively rare in postmenopausal women. Postmenopausal virilization may result from androgen-producing tumors. Androgen-secreting adrenal tumors are rare in clinical practice and are diagnosed as adrenocortical carcinoma, most of which can co-secrete androgen and cortisol. Highly elevated serum testosterone level with normal adrenal androgens such as dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS) and androstenedione is usually regarded as ovary origin. Here we describe an unusual case of a postmenopausal woman with markedly elevated serum testosterone level, while DHEAS, androstenedione, 17-hydroxyprogesterone and cortisol were within the normal range.

CASE PRESENTATION

A 67-year-old postmenopausal woman with hirsutism in the upper lip and armpit, accompanied by clitoromegaly for 5 months. Hormonal evaluation showed markedly elevated serum testosterone level (714.8 ng/ml), whereas DHEAS, androstenedione, 17-hydroxyprogesterone, and cortisol were within the normal range. Imaging examination showed a mass of 1.5 cm in diameter in the left adrenal gland and normal appearance of both ovaries. PET-CT indicated that it was a case of benign adrenal adenoma and excluded ovarian abnormalities and other ectopic tumors. Thus, a pure testosterone-secreting adrenal tumor was suspected and then adrenalectomy was performed. Histology and immunohistochemistry furtherly confirmed the benign adrenocortical adenoma with immunohistochemistry positive for inhibin α, melan A, β-captenin, SYN (focal), Ki-67(< 3%), and negative for chromogranin (CgA), cytokeratin (CK), S-100, P53. After surgery, the level of testosterone returned to normal range and the clinical symptoms also subsided.

CONCLUSIONS

Pure testosterone-secreting adrenal adenomas are extremely rare, but it can induce severe hyperandrogenism and virilization. The source identification of hyperandrogenemia only based on the levels of testosterone, DHEAS and androstenedione is limited. It is important to evaluate not only ovaries but also adrenals in all women with virilization particularly during menopause, even their androstenedione, DHEA and DHEAS level are normal.

Combined adrenal and ovarian venous sampling to localize an androgen producing tumor

A postmenopausal woman presented with hirsutism and elevated serum testosterone levels. A 1-cm adrenal adenoma was noted on computed tomography. Combined adrenal and ovarian venous sampling was performed to localize an androgen producing tumor to the left ovary. The patient underwent a bilateral salpingo-oophrectomy and was spared an unnecessary adrenalectomy.

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.

Low leptin level in an obese hyperandrogenic woman--potential marker for androgen-secreting tumor

Hyperandrogenism in postmenopausal women is due to ovarian hyperthecosis or an androgen-secreting ovarian/adrenal tumor. Making the correct diagnosis might be complicated due to the possible existence of an adrenal neoplasm secreting testosterone only, ectopic ovarian tissue or ectopic luteinizing hormone/human chorionic gonadotropin receptors in the adrenals, as well as the relatively low sensitivity of imaging techniques (computed tomography, magnetic resonance imaging) and vein catheterization for this type of pathology. We present the case of an obese postmenopausal woman with metabolic syndrome, hyperandrogenism (high testosterone levels, suppressed gonadotropins), adrenal macronodular hyperplasia and Leydig-cell ovarian tumor. At presentation she had low leptin levels despite high body fat content. After a catheter study left adrenalectomy was carried out but hyperandrogenism persisted. Then, bilateral oophorectomy with hysterectomy was performed and a small Leydig-cell tumor was found in the left ovary. Postoperatively, testosterone and gonadotropin levels were normal (postmenopausal) and leptin level became elevated without change in body mass index or body fat content. In conclusion, we speculate that low leptin levels in obese hyperandrogenic women might be a marker for androgen-secreting tumors.

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.
