A Sertoli-Leydig cell tumor and pregnancy. Clinical, endocrine, radiologic, and electron microscopic findings

Does surgery to preserve fertility in Sertoli-Leydig cell tumours increase the likelihood of spontaneous conception?

A nulligravida in her 30s presented with primary infertility and secondary amenorrhoea. General examination revealed virilisation; sonological examination detected a right ovarian solid mass. International Ovarian Tumour Analysis (IOTA) was suggestive of malignancy and serum testosterone was raised. A strong clinical suspicion and negative tumour markers pointed towards androgen producing sex cord stromal ovarian neoplasm. MRI excluded pelvic lymphadenopathy. Given the patient's desire for conception, fertility sparing staging laparotomy was done. Histopathology confirmed Sertoli-Leydig cell tumour (SLCT) International Federation of Gynaecology and Obstetrics stage IA. Serum testosterone fell drastically by day 10. Spontaneous menstruation resumed within 30 days. The significance of SLCTs as a differential diagnosis in young women with secondary amenorrhoea and virilising features underscores the role of fertility-preserving surgery in certain circumstances. Here we discuss the clinical features, diagnostic challenges and management strategies for SLCTs, emphasising the need for multidisciplinary collaboration and option of fertility preservation in early stages.

Ovarian luteoma masses in pregnancy: an uncommon cause of virilisation

Pregnancy luteoma is a benign ovarian tumour that presents during pregnancy and regresses spontaneously post partum. The mass may secrete androgenic hormones which can result in virilisation of mother and female foetus. Clinical presentation of pregnancy luteoma is varied from asymptomatic to significant virilisation. We present two cases of ovarian luteomas identified incidentally at caesarean section. The first case had marked hirsutism, while the second case had mild acne. Both foetuses were male and appeared unaffected at birth. Where maternal virilisation is identified during pregnancy, differential diagnoses including pregnancy luteoma should be considered.

Bilateral sertoli-leydig cell tumor in a primigravida: a rare case

We present a unique case of incidentally discovered bilateral Sertoli Leydig cell tumour in a primigravida who displayed no features of virilization. The apha fetoprotein levels were elevated. Magnetic resonance imaging was suggestive of ovarian tumors, possibly germ cell tumor. Bilateral salpingo-oophorectomy was performed and histopathology showed features of Sertoli Leydig cell tumor with intermediate to poor differentiation. Immunohistochemistry was positive for calretinin and inhibin, while cytokeratin was negative. Four courses of bleomycin-, etoposide- and cisplatin-based chemotherapy regimen was started, but the patient aborted while receiving the second cycle of chemotherapy. She received the remaining two cycles of chemotherapy and is now on close follow up with monitoring of serum inhibin levels to detect any tumor recurrence. Bilateral Sertloli Leydig cell tumor has not been reported previously in a pregnant female. The aim of this article is to describe the clinical, radiological and pathological features and management of this rare entity.

Feto-maternal outcomes of pregnancy complicated by ovarian sex-cord stromal tumor: a systematic review of literature

Sex-cord stromal tumors (SCSTs) are rare ovarian cancers and their behavior during pregnancy is not well understood. To evaluate the maternal and fetal outcomes of pregnancy complicated by ovarian SCST, a systematic literature search was conducted in PubMed/MEDLINE using entry key words "pregnancy" and each type of ovarian SCST ("sex cord stromal tumor," "granulosa cell tumor," "thecoma," "Sertoli-Leydig cell tumor," or "gynandroblastoma") between 1955 and 2012 that identified 46 cases eligible for the analysis. Clinical characteristics, pregnancy outcome, tumor characteristics, and survival outcomes were evaluated. Serious adverse events were defined as complications related to the SCST that resulted in severe morbidity or mortality for mother, fetus, or both. The most common histology was granulosa cell tumor (22.0%), followed by thecoma (18.6%) and Sertoli-Leydig cell tumor (8.5%). Abdomino-pelvic pain (45.7%), palpable mass (30.4%), and virilization (26.1%) were the three most common symptoms. The majority were stage I (76.1%), tumor size <15cm (64.9%), and underwent unilateral adnexectomy (80.4%). Fetal conservation surgery was seen in 54.3%. Most cases had live births (78.3%) at full term (60.9%). Among cases proceeded expectant delay of delivery (45.7%), most cases resulted in live birth (95.2%) with median expectant interval of 20.7 weeks. Maternal and/or fetal serious adverse events (SAEs) were observed in 41.3% with maternal shock/hemoperitoneum being the most common complication (13.0%). Logistic regression test identified younger age (<30 versus ≥30, 73.3% versus 26.7%, odds ratio [OR] 11.7, 95%CI 1.35-101, p=0.026), large tumor (size ≥15cm versus <15cm, 64.9% versus 35.1%, OR 10.0, 95%CI 1.29-26.2, p=0.004), and advanced-stage (stages II-IV versus I, 76.1% versus 23.9%, OR 5.82, 95%CI 2.05-48.9, p=0.022) as risk factors of increased SAE. Overall survival of patients diagnosed with ovarian SCST during pregnancy was comparable to ovarian SCST not related to pregnancy (5-year rate, stages I and II-IV, 100% and 70.0%, respectively). In conclusion, although the majority of cases resulted in live birth, ovarian SCST-complicated pregnancy falls into the category of high-risk pregnancy. Risk factors for SAE identified in our study will help to guide strategic management of pregnancy complicated by ovarian SCST.

Virilization during pregnancy with spontaneous resolution postpartum: a case report and review of the English literature

The incidence of gestational hyperandrogenism secondary to ovarian pathology is low. However, when the condition does exist, diagnosis should be made with minimally invasive modalities. It is important to provide appropriate medical/surgical intervention without disturbing the pregnancy iatrogenically or causing unnecessary maternal morbidity. This case report adds to the existing radiographic data concerning this rare obstetrical condition. Presented is a review of the English literature on virilizing ovarian tumors during pregnancy, and a discussion of an approach to managing these tumors when they occur during pregnancy.

Technical difficulties of selective venous blood sampling in the differential diagnosis of female hyperandrogenism

To determine glandular steroid release of adrenals and ovaries in female hyperandrogenism, a standardized method for percutaneous transfemoral venous blood sampling was developed. In eight volunteers and 67 patients, catheterization was performed during the early follicular phase (days 3-7; between 8 and 10 a.m.) to reduce interference from cyclic and circadian variations of secretion. Serial samplings reduced the episodic effluent changes. Anatomical variations and collateral flow as well as stress effects and the dosage of contrast media were studied. During catheterization, peripheral cortisol levels did not differ significantly from control groups. Collaterals had no effect on hormone levels. Contrast media increased cortisol effluent levels only when they were sampled following venography. Four-vessel venous sampling was found to be indicated if peripheral testosterone was more than 1.5 ng/ml and/or dehydroepiandrosterone sulfate more than 6,700 ng/ml. If an ovarian (adrenal)/peripheral gradient of testosterone exceeded 2.7 ng/ml, surgical intervention for tumor removal at the site of hormone excess was felt to be necessary.

Ovarian and adrenal vein steroids in seven patients with androgen-secreting ovarian neoplasms: selective catheterization findings

Standardized bilateral ovarian-adrenal vein catheterization was utilized to preoperatively assess glandular steroid release in seven consecutive cases of occult virilizing gonadal neoplasms. Peripheral testosterone (T) exceeded 1.5 ng/ml in all instances (range, 1.51 to 8.67 ng/ml). Endoscopy and radiography failed to locate the functional lesions. Catheterization showed a unilateral elevation of the ovarian-peripheral vein gradient for T greater than 2.7 ng/ml in six women. In the remaining patient, gradient analysis ruled out an adrenal tumor but did not facilitate lateralization of the gonadal lesion due to subselective ovarian effluent sampling. In addition to the consistent hypersecretion of T, variable excess gonadal output of dihydrotestosterone, androstenedione, dehydroepiandrosterone, and 17 alpha-hydroxyprogesterone was evident. Associated adrenal androgenic hyperfunction was documented in three subjects. Histologic evaluation of the implicated ovaries revealed three lipid cell, two Leydig cell, and two Sertoli-Leydig cell tumors, respectively, measuring between 0.6 and 2.2 cm in diameter. No correlation was found between any of the following parameters: peripheral or glandular vein steroid levels, androgen gradients, severity of symptoms, tumor morphology, and tumor size. In conclusion, appropriate application of selective catheterization may considerably reduce the frequency and extent of operative intervention.

Ovarian and adrenal vein steroids in patients with nonneoplastic hyperandrogenism: selective catheterization findings

Standardized bilateral ovarian-adrenal vein catheterization was utilized to assess directly glandular steroid release in 60 androgenized women without evidence of a functional neoplasm. Testosterone (T), dihydrotestosterone (DHT), androstenedione (delta 4 A), dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), 17-hydroxyprogesterone (17-OHP), and cortisol (F) were measured by radioimmunoassay in samples obtained from a peripheral vein and the four glandular veins (all values are given as nanograms per milliliter, mean +/- standard deviation). Peripheral values were as follows: T, 0.68 +/- 0.43; DHT, 0.32 +/- 0.13; delta 4 A, 2.2 +/- 2.0; DHEA, 8.8 +/- 8.9; DHEA-S, 3137 +/- 1774; 17-OHP, 2.0 +/- 3.0; and F, 216 +/- 121. Peripheral elevations of at least one androgen were found in 80% of the 60 cases (T, 38%; DHT, 18%; delta 4 A, 50%; DHEA, 45%; and DHEA-S, 37%). Ovarian-peripheral vein gradients ( OPGs ) and adrenal-peripheral vein gradients ( APGs ) served as semiquantitative estimates of glandular secretion. OPGs were as follows: T, 0.4 +/- 1.1; DHT, 0.1 +/- 0.2; delta 4 A, 3.4 +/- 7.0; DHEA, 14.6 +/- 100; DHEA-S, -288 +/- 523; 17-OHP, 4.5 +/- 8.4; and F, -35 +/- 47. APGs were as follows: T, 0.88 +/- 1.3; DHT, 1.1 +/- 0.9; delta 4 A, 14.4 +/- 38.4; DHEA, 327 +/- 367; DHEA-S, 854 +/- 1223; 17-OHP, 20.8 +/- 41.3; and F, 1252 +/- 2023. Excess ovarian and/or adrenal androgen output was assumed in a given individual when one or more of the respective T, DHT, delta 4 A, DHEA, and DHEA-S gradients exceeded the upper 95% confidence limits of normal previously established in this laboratory.(ABSTRACT TRUNCATED AT 250 WORDS)

Ovarian and adrenal vein steroids in healthy women with ovulatory cycles--selective catheterization findings

Bilateral ovarian-adrenal vein catheterization and androgen measurements in the efferent samples were utilized to directly assess glandular steroid release in 8 healthy volunteers with proven ovulatory cycles during the early follicular phase. Side effects did not occur in any of the women. Hormone levels were as follows (mean +/- SD; ng/ml) T: peripheral vein (PV) 0.36 +/- 0.16, ovarian veins (OV) 0.39 +/- 0.13, adrenal veins (AV) 0.85 +/- 0.63; dihydro-T (DHT): PV 0.25 +/- 0.09, OV 0.29 +/- 0.10, AV 0.93 +/- 0.65; delta 4-androstendione (A): PV 0.88 +/- 0.34, OV 1.82 +/- 1.04, AV 9.22 +/- 8.04; DHEA; PV 5.13 +/- 1.96, OV 6.73 +/- 2.69, AV 146.79 +/- 217.24; DS PV 1860 +/- 850, OV 1937 +/- 1039, AV 2567 +/- 1201; 17 alpha-hydroxyprogesterone (17P): PV 0.60 +/- 0.19, OV 1.46 +/- 1.64, AV 6.94 +/- 6.20; F: PV 170 +/- 50, OV 130 +/- 21, AV 788 +/- 1320; the bilateral differences of effluent levels were not significant. Glandular-peripheral vein steroid gradients served as semiquantitative estimates of momentary secretory activity; they were as follows (mean +/- SD; ng/ml) T: ovarian-peripheral vein gradient (OPG) 0.03 +/- 0.09, adrenal-peripheral vein gradient (APG) 0.48 +/- 0.57; DHT: OPG 0.05 +/- 0.05, APG 0.69 +/- 0.60; A: OPG 0.97 +/- 1.13, APG 8.33 +/- 7.86; DHEA: OPG 1.70 +/- 1.80, APG 141.80 +/- 216.60; DS: OPG 191 +/- 72, APG 706 +/- 824; 17P: OPG 0.87 +/- 1.67, APG 6.30 +/- 6.10; F: OPG 38 +/- 11, APG 610 +/- 1329. Gradient, analysis revealed that the ovaries produced significant quantities of A, DHEA and 17P, but no T, DHT or F between day 3-7 of the cycle; direct gonadal DS output was detected in 2 individuals. A significant OPG for DS was detected in two individuals possibly indicating its partially gonadal origin. The adrenals released larger amounts of A, DHEA and 17P than the ovaries at this stage (P less than 0.05); also, they consistently secreted T, DHT, DS and F.
