Testicular adrenal rest tumor in the background of congenital adrenal hyperplasia / [Testicularis adrenalis rest tumor a congenitalis adrenalis hyperplasia hátterében]

The prevalence of testicular adrenal rest tumours varies in different forms of congenital adrenal hyperplasia. Patients with 21-hydroxilase deficiency usually have bilateral and palpable testicular nodules. Although adrenal rest tumours are well documented in the literature, the diagnosis and management require a multidisciplinary approach: the cooperative work of endocrinologists, urologists, pathologists and radiologists is essential. In the case of an early diagnosis, appropriately increased corticosteroid treatment may reduce the tumour mass. In advanced stages, tumours can lead to irreversible parenchymal damage causing infertility. The importance of an early and accurate diagnosis cannot be emphasized enough, since the therapy differs significantly from other benign or malignant testicular neoplasia. A case of a testicular adrenal rest tumour is presented along with the multidisciplinary perspectives of the diagnosis and management of these lesions. Orv Hetil. 2020; 161(16): 623­631.

Testicular Adrenal Rest Tumors: Current Insights on Prevalence, Characteristics, Origin, and Treatment.

This review provides the reader with current insights on testicular adrenal rest tumors (TARTs), a complication in male patients with congenital adrenal hyperplasia (CAH). In recent studies, an overall TART prevalence of 40% (range, 14% to 89%) in classic patients with CAH is found. Reported differences are mainly caused by the method of detection and the selected patient population. Biochemically, histologically, and molecularly, TARTs exhibit particular adrenal characteristics and were therefore thought to originate from aberrant adrenal cells. More recently, TARTs have been found to also exhibit testicular characteristics. This has led to the hypothesis of pluripotent cells as the origin of TARTs. High concentrations of ACTH could cause hyperplasia of these pluripotent cells, as TARTs appear to be associated with poor hormonal control with concomitant elevated ACTH. Unfortunately, as yet there are no methods to prevent the development of TARTs, nor are there guidelines to treat patients with TARTs. Intensified glucocorticoid treatment could improve fertility status in some cases, although studies report contradicting results. TARTs can also lead to irreversible testicular damage, and therefore semen cryopreservation could be offered to patients with TARTs. Further research should focus on the etiology and pharmacological treatment to prevent TART development or to treat TARTs and improve the fertility status of patients with TARTs.

Testicular adrenal rest tumors.

We report a case of congenital adrenal hyperplasia in a 29 year old patient, who presented with testicular pain, bilateral testicular masses, and oligospermia. Ultrasonography confirmed, in both testis, the presence of heterogeneous and hypoechoic lesions with irregular borders and internal and peripheral vascularization. Seric tumor markers were negative. The patient was scheduled for perioperative testicular biopsy and bilateral orchiectomy. Perioperative biopsy was suggestive of testicular adrenal rest tumor and not additional procedure was performed. Treatment was initiated with high doses of glucocorticoids, decreasing the size of testicular masses and testicular pain was alleviated.

Testicular tumors of adrenogenital syndrome: From physiopathology to therapy.

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.

Testicular adrenal rest tumors in a patient with congenital adrenal hyperplasia.

Congenital adrenal hyperplasia refers to a group of autosomal recessive disorders caused by a deficiency of an enzyme involved in the synthesis of glucocorticoids. The enzyme deficiency generally leads to a deficiency of cortisol and/or aldosterone production within the adrenal cortex. The lack of glucocorticoids generally leads to elevated levels of plasma corticotropin (ACTH), which often results in adrenal hyperplasia. Testicular adrenal rest tumors may develop in males with congenital adrenal hyperplasia due to overstimulation of aberrant adrenal cells within the testes. Recognition of this disease entity is essential when evaluating young males with testicular masses.

[Testicular adrenal rest tumors in adolescents]. / Testikuläre adrenale Resttumoren im Hoden bei Adoleszenten.

BACKGROUND: Testicular adrenal rest tumors (TART) frequently occur in patients with congenital adrenal hyperplasia (CAH) and can be detected and treated in childhood as well as in adolescence. Due to the intricate dilimitation to other testicular masses the correct diagnosis of TART can be problematic. An extensive endocrinologic evaluation and ultrasound examination are mandatory. Even though TART are benign lesions a high-dose therapy with glucocorticoid and/or mineralocorticoid suppletion is necessary for protecion or regain of fertility. METHODS: A surgical approach can be considered, depending on stage of disease and response on drug therapy. Consequent treatment and constant therapy monitoring might significantly improve long-term outcome. RESULTS: Currently there is no validated standard therapy concept, which can be explained by the heterogenity of disease patterns progression and the limited data available, respectively. Therefore treatment should be subject to specialized centres.

Clinical analysis of management of pediatric testicular germ cell tumors.

OBJECTIVE: To analyze our experiences of pediatric testicular tumors and investigate the management of pediatric testicular germ cell tumors. Pediatric testicular tumors are rare and the treatment of them has not been well defined. METHODS: Children treated for primary testicular tumors between January 1998 and July 2010 were retrospectively analyzed. For yolk sac tumor, the difference of survival rates between patients with and without retroperitoneal lymph node dissection (RPLND) was calculated. RESULTS: Eighty-seven cases met our criteria and 78 were germ cell tumors, including 40 cases with yolk sac tumor. Patients were 3-128 months old (median 19), and 53 patients were diagnosed at younger than 2 years of age. For germ cell tumors, serum α-fetoprotein and ß-human chorionic gonadotropin were elevated in 48 and 7 patients, respectively, including 38 and 2 in those with yolk sac tumor. RPLND and chemotherapy were performed in 13 and 19 patients, respectively, and surveillance was performed in 50 patients. With median follow-up of 50 months, 6 patients had recurrence, 4 patients died, and the others achieved complete remission. For stage I yolk sac tumor, the difference of survival rates between patients with and without RPLND was not significant (P = .808). CONCLUSION: Yolk sac tumor is the most common type of pediatric testicular tumor. For stage I yolk sac tumor, radical inguinal orchiectomy is effective, salvage chemotherapy is promising, and RPLND may not be necessary.

Testicular adrenal rest tumor in infertile man with congenital adrenal hyperplasia: case report and literature review.

CONTEXT: Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH) because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT: We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH), luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.

CONTEXTO: Pacientes com hiperplasia adrenal congênita (HAC) por deficiência da 21-hidroxilase podem ter a síntese de cortisol e de aldosterona prejudicada. Homens com HAC têm baixas taxas de fertilidade em comparação com a população normal, e isso está relacionado a tumores testiculares de remanescente adrenal. A associação de azoospermia e tumor testicular sugere uma causa mecânica, principalmente quando o tumor é encontrado no mediastino testicular. O método preferencial de tratamento consiste na corticoterapia intensa. No entanto, quando o tumor não é responsivo à terapia com esteroides, o tratamento cirúrgico deve ser considerado. RELATO DE CASO: Apresentamos o caso de um paciente do sexo masculino com HAC por deficiência da 21-hidroxilase, portador de tumor testicular e azoospermia. Em consulta prévia com endocrinologista, o paciente começou tratamento com baixas doses diárias de corticoide, porém, após 12 meses de tratamento, não houve mudança significativa no espermograma. Embora os níveis de hormônio adrenocortitrófico e 17-hidroxiprogesterona tenham se normalizado, os níveis séricos de hormônio folículo-estimulante, hormônio luteinizante e testosterona não se alteraram. Exame ultrassonográfico confirmou testículos bilateralmente diminuídos e heterogêneos, além de área em mosaico na projeção da rede testis bilateralmente. Ressonância nuclear magnética confirmou o achado. Biópsia testicular revelou espermatogênese e espermiogênese preservadas em 20 por cento dos túbulos seminíferos no testículo direito. O paciente foi submetido a cirurgia poupadora testicular, com ressecção tumoral. Após 12 meses de acompanhamento, não houve recorrência tumoral, mas o paciente ainda apresentava azoospermia, sendo integrado no programa de injeção intracitoplasmática de espermatozoides.

Testicular adrenal rest tumours in congenital adrenal hyperplasia.

In adult patients with congenital adrenal hyperplasia (CAH) the presence of testicular adrenal rest tumours (TART) is an important cause of gonadal dysfunction and infertility. In the last decade several papers have focused on the origin and pathogenesis of these tumours. In this paper we review the embryological, histological, biochemical and clinical features of TART and discuss the treatment options. Furthermore, we propose a new five-stage classification of TART, based on sonographic, clinical and biochemical parameters, that may lead to a better follow up and treatment of patients with TART.

[Testicular adrenal rest tumors (TART) in adult men with classic congenital adrenal hyperplasia (CAH)]. / Testikuläre adrenale Resttumoren (TART) bei erwachsenen Männern mit klassischem adrenogenitalen Syndrom (AGS).

BACKGROUND: Information about treatment of adult male patients with congenital adrenal hyperplasia (CAH) and testicular adrenal rest tumors (TART) is scarce. Diagnostic and therapeutic guidelines do not exist. The aim of this review is to evaluate the current state of therapeutic options in adult male patients with CAH. METHODS: We performed an extensive search of the literature of the last 10 years by using PubMed/MEDLINE. RESULTS: The aims of treatment in adult male patients with CAH are prevention of adrenal crisis and TART, improvement of general well-being, good quality of life and sexual well-being, fertility, and prevention of side effects of gluco- and mineralocorticoid therapy. However, fertility is impaired in these patients and correlates with TART. The current therapeutic concepts are discussed. CONCLUSIONS: A future system of regular follow-up visits and standards in therapeutic concepts is needed to guarantee an improved fertility and lifelong good quality of life in adult male patients with CAH.

Adrenocortical carcinoma--diagnostic and therapeutical implications.

OBJECTIVE: To evaluate the results of treatment of a consecutive series of patients with adrenocortical carcinoma who presented during the six year period 1985 to 1991. DESIGN: Open study. SETTING: Departments of Surgery, Pathology, Endocrinology, and Clinical Chemistry, Sahlgren Hospital, Göteborg, Sweden. SUBJECTS: 10 consecutive patients, two with recurrent and eight with primary adrenocortical carcinoma. INTERVENTIONS: All patients were treated surgically. Two required preoperative embolisation of the tumour vessels to facilitate excision of particularly large tumours, and eight were given adjuvant treatment with mitotane (o,p'-DDD). RESULTS: At a median follow up of 1.5 years (range 3 months, to 21 years) 6 patients were alive with no radiological or biochemical signs of disease; 2 were alive, but with signs of recurrence (at 3 months and 6 years, respectively); and two had died of their disease (at 4 and 8 months, respectively). For the past two years all patients have had their urinary steroid profiles monitored by gas chromatography and mass spectrometry to detect recurrence of the tumour at the earliest possible stage. CONCLUSION: Operation is the treatment of choice for patients with adrenocortical carcinoma, particularly stages I-III. The role of mitotane as adjuvant treatment can be evaluated only in multicentre studies.
