RESUMO

Testicular adrenal rest tumors (TARTs) are common cause of infertility in males with congenital adrenal hyperplasia (CAH). We studied the role of genotype and disease regulation on TART development, their impact on gonadal function, and frequency in 47 21-hydroxylase deficiency (21-OHD) and four 11-hydroxylase deficiency (11-OHD) male patients. Testicular ultrasound (TU), genotype, hormonal measurement in 51, and spermiogram in five patients were performed. TARTs were detected in 14 SW21-OHD and one 11-OHD patient: 1/8 patients aged <7 years (1.8 years old is the youngest), 1/8 patients aged <12 years, 5/17 patients aged <18 years, and in 8/18 adults. All 21-OHD TART patients had exclusively severe mutations of CYP21A2 gene. Poor hormonal control in 8/15 patients with and 12/36 patients without TART indicates correlation of tumor development with poor disease control. None of the TART patients fathered a child. Low inhibin-B was found in 7/15 TART patients. Azoospermia was found in four and oligoasthenozoospermia in one patient. CONCLUSION: TART was detected exclusively in patients with severe CYP21A2 mutations. Disease regulation plays a role in development of TART that impairs testicular function and increases the risk of infertility. Screening for TART by TU is indicated from early childhood. What is Known: • Due to improved diagnostic and therapeutic possibilities, majority of the male patients with congenital adrenal hyperplasia nowadays reach adulthood and screening for long-term complications is becoming more important. • Testicular adrenal rest tumors (TARTs) are common cause of infertility and impaired gonadal function in males with CAH. What is New: • A 1.8-year-old boy described in this paper is the youngest reported patient with TART. • Screening for TART by testicular ultrasound from early childhood, especially in patients with severe CYP21A mutations, is recommended.

RESUMO

Testicular tumor of adrenogenital syndrome is a rare and benign anomaly usually presenting as bilateral testicular masses. It is the most important cause of infertility in adult male congenital adrenal hyperplasia. Distinction between testicular tumors of adrenogenital syndrome and Leydig cell tumors can be problematic; it is based on clinical, histopathologic, immunohistochemical and endocrine features. Biopsy is advised in cases of longstanding tumors in infertile patients and when surgery is indicated. Fertility preservation is a key management goal in testicular tumor of adrenogenital syndrome. In stages 2 and 3, intensified glucocorticoid treatment is recommended as a first step treatment. Sparing surgical approach is preferred for tumors of stage 4 and steroid unresponsive masses. Magnetic resonance imaging is recommended before surgery. The only indication of surgery in stage 5 is testicular pain.

RESUMO

Objetivo. El propósito de la revisión es mostrar las características de imagen que presentan los tumores corticosuprarrenales pediátricos (TCSP). Material y métodos. Se realiza una revisión retrospectiva de los pacientes diagnosticados de TCSP en nuestro hospital terciario en el periodo comprendido entre los años 2000 y 2010, desde el punto de vista radiológico y anatomopatológico. Se estudian las características radiológicas mediante ecografía, tomografía computarizada (TC) y resonancia magnética (RM), que ayudarán a orientar la lesión hacia benignidad o malignidad, y el seguimiento de imagen. Resultados Se presentan 8 TCSP: 5 carcinomas, 2 adenomas y un tumor borderline; se clasifican 2 en estadio I, uno en estadio II, 3 en estadio III y 2 en estadio IV. La radiología permitió el diagnóstico de carcinoma en estadio IV en 2 casos, dada la presencia de metástasis iniciales en un paciente y el gran tamaño y desestructuración tumoral en otro, desarrollando posteriormente metástasis. En los otros 6 casos el diagnóstico radiológico fue de aproximación respecto a su naturaleza de carcinoma o adenoma. Conclusiones. Los TCSP son raros en la infancia. Engloban las entidades de adenoma y carcinoma, siendo difíciles de diferenciar histológica y radiológicamente en ausencia de infiltración vascular y/o metástasis. En un paciente en edad pediátrica la combinación de una masa suprarrenal y signos clínicos de hiperfunción corticosuprarrenal es virtualmente diagnóstica de TCSP (AU)


Objective. This article aims to show the imaging characteristics of pediatric adrenocortical tumors. Material and methods. We review the imaging and histological findings in patients diagnosed with pediatric adrenocortical tumors at our tertiary hospital between 2000 and 2010. We analyze the findings at ultrasonography, computed tomography, and magnetic resonance imaging that can help orient the diagnosis toward benign or malignant lesions and guide imaging follow-up. Outcome. We found 8 adrenocortical tumors in children: 5 carcinomas, 2 adenomas, and 1 borderline tumor. Two tumors were classified as stage I, 1 as stage II, 3 as stage III, and 2 as stage IV. Imaging enabled the diagnosis of stage IV carcinoma in 2 cases, due to the presence of initial metastases in one patient and to size of the tumor and structural changes in the other, who later developed metastases. In the other 6 cases, the imaging studies oriented the diagnosis toward carcinoma or adenoma. Conclusions. Adrenocortical tumors are rare in children. Adrenocortical tumors include adenomas and carcinomas, and in the absence of vascular infiltration and/or metastases it is difficult to differentiate between the two types by imaging and histology. The combination of an adrenal mass and clinical signs of adrenocortical hyperfunction in a child is virtually diagnostic of an adrenocortical tumor (AU)

RESUMO

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder with impaired function of the adrenal cortex caused by mutations in the CYP21A2 gene. Deficiency of steroid 21-hydroxylase accounts for 80-95% of CAH cases. Testicular adrenal rest tumours (TART) may be prevalent in up to 95% of CAH adults and may already appear during childhood. Whether genotype sub-types can account for the development of TART has not been investigated previously. We therefore investigated this by coupling clinical information of CAH patients with information of their genetic mutation. In 49 male patients (age 2.6-40.3 years) with 21-hydroxylase deficiency, testicular ultrasound examinations were performed and CYP21A2 genotypes determined. These were grouped according to the residual 21-hydroxylase activity: group Null (complete enzyme impairment), group A (almost complete enzyme impairment), group B (severe enzyme impairment) and group C (partial impairment). TART were observed in 27 of 49 patients (55%). For the 23 patients younger than 18 years, TART were present in 11 (48%), the youngest patient being 7.5 years old. The presence of TART was dependent on the CYP21A2 genotype: 27 of 37 patients (73%) with the most severe mutations (groups Null and A) had TART, whereas none of 12 patients with the milder mutations (groups B and C) had TART. We conclude that TART were most frequently detected in patients with severe CYP21A2 mutations, and may occur already in early childhood in such patients.

RESUMO

OBJECTIVE: To evaluate the histological features of testicular tumors and residual testicular parenchyma in male patients with congenital adrenal hyperplasia (CAH) and longstanding bilateral testicular adrenal rest tumors (TART). DESIGN: Descriptive study. SETTING: University medical center in the Netherlands. PATIENT(S): Seven male patients who had CAH with longstanding bilateral TART and who were treated with testis-sparing surgery. INTERVENTION(S): Enucleation of TART and taking biopsies of the surrounding testicular parenchyma. MAIN OUTCOME MEASURE(S): Description of the histological features of TART and residual testicular parenchyma. RESULT(S): All tumors had a similar histological appearance, with sheets of polygonal cells separated by dense fibrous tissue with focal lymphocytic infiltrates and without Reinke crystals. All biopsies showed a decrease in tubular diameter with peritubular fibrosis and, in four patients, tubular hyalinization. The germinative layer showed decreased spermatogenesis and reduced Johnsen scores. CONCLUSION(S): Testicular adrenal rest tumors can lead to end-stage damage of testicular parenchyma, most probably as a result of longstanding obstruction of the seminiferous tubules. Therefore, treatment at an early stage is advised.

RESUMO

CONTEXT: Infertility observed in adult males with congenital adrenal hyperplasia (CAH) has been associated with testicular adrenal rest tumors (TART) that may originate during childhood. OBJECTIVE: Our objective was to describe the prevalence of TART and Sertoli and Leydig cell function in a group of boys aged 2-10 yr with CAH and to compare prevalence with that of a control group. DESIGN: From August 2005 to January 2007, 19 patients with classical CAH (CAH group) were referred from seven endocrinology centers. METHODS: We studied 19 subjects in the CAH group and, as a control group, 13 boys from the community that did not have testicular diseases. A complete physical exam was performed. High-resolution ultrasound was used to determine TART prevalence. Inhibin B and anti-Müllerian hormone were used as Sertoli cell markers. The ratio between basal testosterone levels and testosterone levels 72 h after beta-human chorionic gonadotropin (5000 U/m2) treatment [(T72- T0)/T0] was used to evaluate Leydig cell response. RESULTS: CAH and control groups were comparable in chronological age (5.9 vs. 5.6 yr; P = 0.67) and bone age/chronological age ratio (1.09 vs. 1.03; P = 0.09). TART prevalence was four of 19 (21%) in the CAH group. Lower values for inhibin B (49.2. vs. 65.2 pg/ml; P = 0.018), anti-Müllerian hormone (70.1 vs. 94.2 ng/ml; P = 0.002), and (T72- T0)/T0 (5.6 vs. 13.6; P < 0.01) were observed in the CAH group. CONCLUSION: TART in prepubertal males with classic CAH could be found during childhood. We also report differences in markers of gonadal function in a subgroup of patients, especially in those with inadequate control.

RESUMO

CONTEXT: In male patients with congenital adrenal hyperplasia (CAH), testicular adrenal rest tumors are frequently found that may interfere with gonadal function. OBJECTIVE: Our objective was to determine steroid-producing features of testicular adrenal rest tumors. DESIGN AND SETTING: The study is descriptive and took place at a university medical center. PATIENTS: Eight adult CAH patients with bilateral testicular adrenal rest tumors were treated with testis-sparing surgery. INTERVENTIONS: In all but one patient, spermatic veins were cannulated during surgery and blood samples collected to measure the adrenal-specific steroid 21-deoxycortisol (21DF) and 17-hydroxyprogesterone (17OHP) and androstenedione (A). The same parameters were measured in simultaneously taken peripheral blood. mRNA concentrations of adrenal-specific enzymes CYP11B1 and CYP11B2 and ACTH and angiotensin II (AII) receptors were measured in tumor tissue. MAIN OUTCOME MEASURES: Adrenal-specific steroids/enzymes were assessed. RESULTS: 21DF, 17OHP, and A levels were measurable in all spermatic vein samples. The ratio (mean +/- SD) between spermatic vein and simultaneously taken peripheral blood samples was 37.8 +/- 56.3 (21DF), 132.0 +/- 249 (17OHP), and 57.0 +/- 68.2 (A). CYP11B1, CYP11B2, and ACTH and AII receptor mRNAs were detected in all tumors with a strong correlation between ACTH receptor mRNA in tumors and 21DF (r = 0.85; P = 0.015), 17OHP (r = 1; P = 0.01) and A (r = 0.89; P = 0.007) concentrations in peripheral blood. CONCLUSION: Testicular adrenal rest tumors produce adrenal-specific steroids and express adrenal-specific enzymes and ACTH and AII receptors, confirming the strong resemblance with adrenal tissue. Because AII receptors are present in tumor tissue, it can be hypothesized that AII may be an additional factor responsible for testicular adrenal rest tumor growth.

RESUMO

CONTEXT: In male patients with congenital adrenal hyperplasia (CAH), testicular adrenal rest tumors (TART) are frequently present. These tumors can interfere with testicular function. Intensifying glucocorticoid therapy does not always lead to tumor regression and improvement of testicular function. Recently, testis-sparing surgery was introduced for treatment of TART. OBJECTIVE: The aim of this study was to evaluate tumor volume, symptoms, and pituitary-gonadal function in male patients with CAH caused by 21-hydroxylase deficiency and bilateral TART before and after testis-sparing surgery. SETTING: This study was conducted at Radboud University Nijmegen Medical Centre in The Netherlands. PATIENTS: Eight adult male CAH patients with bilateral TART and infertility were included. INTERVENTIONS: Evaluation of testicular magnetic resonance imaging, symptoms, fasting serum concentrations of ACTH, LH, FSH, inhibin B, 17-OH progesterone, androstenedione, testosterone, and estrone, and semen analysis (six of eight patients) was performed before and 6 and 22 months after testis-sparing surgery. MAIN OUTCOME MEASURES: The main outcome measures were absence of residual tumor and improvement of symptoms and pituitary-gonadal function. RESULTS: Residual tumors were not found on any of the patients' magnetic resonance imaging after surgery. Two patients reported testicular pain and discomfort that disappeared after surgery. Parameters of pituitary-gonadal function did not improve after surgery: semen analysis showed azoospermia (five patients) or oligospermia (one patient) without improvement, and all patients had persistently low inhibin B concentrations. CONCLUSION: Testis-sparing surgery did not improve pituitary-gonadal function despite successful removal of the tumors. Further studies are needed to investigate whether surgery at an earlier stage in the natural history of TART can prevent permanent testicular damage.

RESUMO

UNLABELLED: Fertility in women with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency appears to be reduced. The purpose of this review is to summarize the reported evidence about subfertility in women with CAH and to review the causes of reduced fertility. Compared with a non-CAH female population, pregnancy and live-birth rates are severely reduced in salt-wasting patients, mildly reduced in simple virilizing patients, and normal in nonclassical patients. Several factors have been suggested to contribute to the impaired fertility in CAH females: adrenal overproduction of androgens and progestins (17-hydroxyprogesterone and progesterone), ovarian hyperandrogenism, polycystic ovary syndrome, ovarian adrenal rest tumors, neuroendocrine factors, genital surgery, and psychological factors such as delayed psychosexual development, reduced sexual activity and low maternal feelings. It is obvious that these factors are interrelated. Improving endocrine, surgical, and psychological management could contribute to improving fertility chances in these patients. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader will be able to define the various types of CAH, to describe the fertility issues in the CAH patients, to outline the various other causes of hyperandrogenism, and to list the treatment options for the patient with CAH.

RESUMO

A case of adrenal rest tumor arising in the liver of a 62-year-old male with chronic hepatitis type C is reported. The tumor was clinically non-functioning and required distinction from hepatocellular carcinoma. The yellowish-brown tumor measured 25 x 18 x 15 mm and was located in the subcapsular portion of the right hepatic lobe. Histologically, the tumor presented features similar to those of the adrenal cortex and was predominantly composed of pale cells. Electron micrograph revealed lipid droplets and mitochondria with tubulo-vesicular cristae, consistent with the characteristics of steroid-producing cells. Immunohistochemically, the tumor expressed the adrenal 4 binding protein and a number of enzymes involved in the synthesis of adrenocortical steroids. At surgery, the right adrenal gland was present independently from the liver. This hepatic tumor was considered to be an adrenal rest tumor with steroidogenic capability.

RESUMO

Se presenta el caso de un niño de ocho años de edad con hiperplasia suprarrenal congénita por deficiencia de 21-hidroxilasa, e hiperplasia de restos adrenales paratesticulares, que fue diagnosticada inicialmente como portador de un tumor de células de Leydig, proponiéndosele orquiectomía bilateral. El estudio mediante prueba de inhibición con dexametasona y posteriormente de estimulación con ACTH evidenció el defecto enzimático y permitió establecer el diagnóstico de certeza. Posteriormente, aún bajo inhibición con dexametasona, se realizaron pruebas de estimulación con hormona hipotalámica liberadora de gonadotropina y gonadotropina coriónica humana, que establecieron la existencia de pubertad precoz verdadera asociada a su patología de base, y probablemente secundaria a sensibilización hipotalámica por exposición crónica a un medio hiperandrogénico
