Cortisol production by testicular tumors in a patient with congenital adrenal hyperplasia (21-hydroxylase deficiency)

11-Oxygenated Androgens Are Biomarkers of Adrenal Volume and Testicular Adrenal Rest Tumors in 21-Hydroxylase Deficiency

CONTEXT

Patients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes.

OBJECTIVE

To identify biomarkers of disease control and long-term complications in 21OHD.

SETTING AND PARTICIPANTS

Cross-sectional study of 114 patients (70 males), ages 2 to 67 years (median, 15 years), seen in a tertiary referral center.

METHODS

We correlated a mass-spectrometry panel of 23 steroids, obtained before first morning medication, with bone age advancement (children), adrenal volume (adults), testicular adrenal rest tumors (TART), hirsutism, menstrual disorders, and pituitary hormones.

RESULTS

Total adrenal volume correlated positively with 18 steroids, most prominently 21-deoxycortisol and four 11-oxygenated-C19 (11oxC19) steroids: 11β-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11ketoA4), 11β-hydroxytestosterone (11OHT), and 11-ketotestosterone (11ketoT) (r ≈ 0.7, P < 0.0001). Nine steroids were significantly higher (P ≤ 0.01) in males with TART compared with those without TART, including 11OHA4 (6.8-fold), 11OHT (4.9-fold), 11ketoT (3.6-fold), 11ketoA4 (3.3-fold), and pregnenolone sulfate (PregS; 4.8-fold). PregS (28.5-fold) and 17-hydroxypregnenolone sulfate (19-fold) levels were higher (P < 0.01) in postpubertal females with menstrual disorders. In males, testosterone levels correlated positively with all 11oxC19 steroids in Tanner stages 1 and 2 (r ≈ 0.7; P < 0.001) but negatively in Tanner stage 5 (r = -0.3 and P < 0.05 for 11ketoA4 and 11ketoT). In females, testosterone level correlated positively with all four 11oxC19 steroids across all Tanner stages (r ≈ 0.8; P < 0.0001).

CONCLUSION

11oxC19 steroids and PregS might serve as clinically useful biomarkers of disease control and long-term complications in 21OHD.

Molecular characterization of testicular adrenal rest tumors in congenital adrenal hyperplasia: lesions with both adrenocortical and Leydig cell features

CONTEXT

Testicular adrenal rest tumors (TART) are one of the major long term complications in patients with congenital adrenal hyperplasia. Although several adrenal-like properties have been assigned to these benign lesions, the etiology has not been confirmed yet.

OBJECTIVE

The aim of this study was to describe TART in more detail by analyzing several (steroidogenic) characteristics that may be classified as adrenal cortex or Leydig cell specific.

METHODS

Gene expression analysis by qPCR was performed for 14 genes in TART tissue (n = 12) and compared with the expression in healthy control fibroblasts (nonsteroidogenic control). In addition, a comparison was made with the expression levels in testis tissue (n = 9) and adrenal tissue (n = 13).

RESULTS

Nearly all genes were highly expressed in TART tissue, including all genes that encode the key steroidogenic enzymes. TART expression levels are in the majority almost identical to those found in adrenal tissue. The expression of adrenal cortex specific genes (CYP11B1, CYP11B2, and MC2R) in both TART and adrenal tissue is approximately 1000-10 000 times higher compared to that in testes samples. In addition, the Leydig cell markers INSL3 and HSD17B3 were not only found in testes, but also in TART, both at significantly higher levels than in the adrenal (p < 0.01).

CONCLUSION

Our study shows for the first time that TART have multiple steroidogenic properties, which include not only the expression of adrenal cortex but also of Leydig cell markers. Therefore, the origin of these tumors might be a more totipotent embryonic cell type.

Leydig cell tumor and malignant lymphoma in a patient with nonclassical 21-hydroxylase deficiency

A 46-year-old man was admitted in our hospital with hypoglycemia; his FPG was 43 mg/mL. Five years earlier, he underwent simultaneous surgeries for an adrenal adenoma, a benign Leydig cell tumor (LCT), and a malignant lymphoma. Based on the laboratory results, he was diagnosed as congenital adrenal hyperplasia (CAH) due to nonclassical 21-hydroxylase deficiency (21-OHD). On immunohistochemistry analysis using the antibody against adrenal-specific 11beta-hydroxylase antibody, the LCT showed both properties as a testicular cell and as an adrenal cell. The genetic background of 21-OHD might contribute to the development of malignant lymphoma. Such as a case of LCT and malignant lymphoma in a patient with 21-OHD seems to be rare.

Ovarian adrenal rest tissue in congenital adrenal hyperplasia--a patient report

We report a young girl who died in an Addisonian crisis due to previously undiagnosed congenital adrenal hyperplasia (CAH), in whom ovarian adrenal rest tissue was detected at postmortem histopathological examination. This is a very rare complication in female patients with CAH with only two previously reported cases.

Functioning ovarian tumors: direct and indirect findings at MR imaging

There are many kinds of ovarian tumors and tumorlike conditions that produce estrogen or androgen. Magnetic resonance imaging can demonstrate not only ovarian tumors but also an enlarged uterus with a thick endometrium, even in cases of a clinically latent excess of estrogen. These clinical and indirect imaging findings can aid in the differential diagnosis of ovarian tumors. Granulosa cell tumor and thecoma are well-known estrogen-producing tumors. In pediatric or postmenopausal patients, they manifest as precocious pseudopuberty or postmenopausal bleeding, respectively. Conversely, Sertoli-Leydig cell tumor is representative of hormone-producing tumors that cause virilization. However, there are other functioning ovarian tumors besides the sex cord-stromal tumors. It is well known that metastatic ovarian tumors often have androgen-producing stroma and that mucinous cystadenoma sometimes produces estrogens. Most other ovarian tumors can produce sexual hormones in their stroma. In addition, some endocrinologic abnormalities (eg, polycystic ovary syndrome) also cause virilization.

Testicular "tumor" of the adrenogenital syndrome: a case report of an unusual association with myelolipoma and seminoma in cryptorchidism

BACKGROUND

Males with congenital adrenal hyperplasia may develop bilateral testicular masses in early adult life. These are not malignant and generally regress with corticosteroid therapy. The authors report a case occurring in a 44-year-old man with associated seminoma and myelolipoma in an undescended testis.

METHODS

The testicular tumors were analyzed by histologic, flow cytometric, and ultrastructural techniques.

RESULTS

The tumors in both testes were comprised of polygonal cells with abundant granular eosinophilic cytoplasm, occasionally with brown (lipochrome) pigment and round nuclei of various sizes with prominent nucleoli. These cells were grouped into nodules by dense and sometimes thick fibrous trabeculae in the right testis. The areas corresponding to the fibrous trabeculae in the left (intraabdominal) testis were replaced by mixture of hematopoietic (myeloid) and fatty tissue in various proportions characteristic of myelolipoma. The left testis also had a well demarcated tumor that was diagnostic of seminoma. Electron microscopy demonstrated abundant smooth endoplasmic reticulum, a moderate number of mitochondria with tubulovesicular cristae, lipid droplets, and lipofuscin granules in the polygonal cells. No Reinke's crystals were observed. The patient received corticosteroids for his adrenocorticoid deficiency and also underwent external beam irradiation to the retroperitoneum for seminoma.

CONCLUSIONS

This case illustrates an unusual presentation of a testicular tumor in a patient with the adrenogenital syndrome as well as with myelolipoma and seminoma in a cryptorchid testis. The possibility of an associated neoplasm that could be potentially fatal should be considered whenever a testicular tumor of the adrenogenital syndrome continues to grow despite adequate hormonal treatment.

[Congenital adrenal hyperplasia and testicular hypertrophy]

BACKGROUND

Testicular tumors have been reported in boys and adolescents with congenital adrenal hyperplasia (CAH) inadequately controlled by hormonal therapy.

CASE REPORTS

Two adolescents were treated for CAH due to 21-hydroxylase deficiency. They developed hyperplastic nodular testes at the age of 16 and 17 years, respectively. CAH in both was inadequately controlled as confirmed by hormonal studies. The tumors regressed after adequate steroid therapy in the first patient but persisted in the second patient despite normalization of 17-OH progesterone and plasma renin activity.

CONCLUSION

Testicular ultrasonography should be systematic in all male patients with CAH since radiological findings are earlier than clinical manifestations. The ACTH-dependent tumors require intensification of hormonal therapy in order to obtain tumoral regression and to prevent infertility.

Bilateral testicular adrenal rests in a patient with 11-hydroxylase deficient congenital adrenal hyperplasia

A 13-year-old boy was referred for investigation of hypertension, precocious puberty and giant testicles. Hormonal studies established the diagnosis of congenital adrenal hyperplasia due to 11-hydroxylase deficiency. Testicular biopsy revealed that the scrotal masses were adrenal rest tumors entirely composed of adrenocortical tissue. Primary testicular tissue was absent. The size of the tumors regressed following replacement steroid therapy together with restoration of normal blood pressure. This observation of a testicular adrenal rest tumor in a patient with 11-hydroxylase deficient congenital adrenal hyperplasia is unique.

Characterization of a feminizing testicular Leydig cell tumor by hormonal profile, immunocytochemistry, and tissue culture

A patient with gynecomastia and a nonpalpable testicular Leydig cell tumor is presented. Estradiol and progesterone levels were elevated whereas serum testosterone was reduced. Following removal of the tumor the hormonal values returned to normal with reduction of gynecomastia. Tumor tissue was maintained in culture for 9 days during which high estradiol levels as well as lesser quantities of testosterone and progesterone were demonstrated in the culture medium. Elevation of progesterone supports a block of 17 alpha-hydroxylase activity caused by increased endogenous estradiol. This is the first case of a cultured feminizing testicular Leydig cell tumor in which hormone production was demonstrated. The freshly removed tumor as well as the cultured tissue material were studied by immunocytochemical methods and biochemical analysis of cytoskeletal proteins. These methods revealed vimentin as the exclusive type intermediate sized filament in both. This is the first demonstration of vimentin in a Leydig cell tumor, in agreement with its occurrence in normal Leydig cells.

Infertility caused by bilateral testicular masses secondary to congenital adrenal hyperplasia (21-hydroxylase deficiency)

Two male cousins with partial 21-hydroxylase deficiency presented with bilateral testicular masses and infertility. In both cases, the testicular masses, consisting of adrenocorticotropic hormone-dependent pluripotential cells, were thought to play a major etiologic role in infertility. The administration of very small doses of dexamethasone, given at 11:00 P.M., led to the disappearance of the masses and a subsequent return of fertility. Although 21-hydroxylase deficiency is not by itself an uncommon condition, the presentation of testicular masses with subsequent reversible infertility in two family members with this condition has not previously been described.

Electron microscopic study of testicular tumor in congenital adrenal hyperplasia

Ultrastructural features of bilateral testicular biopsy materials, obtained from both tumor and nontumor areas of the testis of a 27-year-old man with congenital adrenal hyperplasia, revealed a number of pathologic changes. Germ cell hypoplasia and extratubular cellular hyperplasia were noticed in the nontumor portion of the testis. In some areas of the tumor, dense collagenous materials surrounded the compressed degenerative seminiferous tubule. In other areas at least three different types of cells were identified: 1) branched, irregular giant cells, 2) small cells in clusters, and 3) modified myoid or smooth muscle cells. It is suggested that these three types of cells have different origins. The concept that these types of tumor cells originate from "pluripotential cells" is supported.
