Case Report:clinical experience of bilateral giant pediatric Testicular adrenal rest tumors with 3 Beta-Hydroxysteroid Dehydrogenase-2 family history.

ABSTRACT:

Background

We reported a patient with Testicular adrenal rest tumors(TARTs) caused by congenital adrenal hyperplasia(CAH). TARTs occur frequently in CAH population with 21-hydroxylase deficiency(21-OHD). There are few reports of TARTs with 3β-hydroxysteroid dehydrogenase deficiency-2 (3β-2HSD).Furthermore,gaint TARTs are rarely mentioned in reported cases involving affected siblings.

Case presentation

A 14-year-old male patient was admitted by congenital adrenal hyperplasia with progressively increasing bilateral testicular masses.The Patient and his elder brother had been performed mutational and chromosome analysis and biopsy. Hormonal and anthropometric measurements were performed during endocrine treatments. We successfully performed surgery and excised two 83mm×46mm×44mm and 74mm×49mm×31mm tumors. Our pathology and immunochemistry tests have proven TARTs in patient. At first, both siblings received regular doses of hydrocortisone and fludrocortisones and tumor size regressed. During the one-year irregular intake due to Covid-19 pandemic, endocrine treatment became insensitive and tumor size slowly increased. The gene analysis reported two novel mutations C.776 C>T and C.674 T>A. The C.776 C>T is from father and has been reported. The C.674 T>A inherited from mother and cannot found in gene library and may related to TARTs.

Conclusions

This case illustrates inadequate hormone therapy could cause tumor enlargement. It is essential to seek for ultrasound examination once suspected scrotal mass occurred.It is necessary to adjust endocrine medicine or adopt surgery in refractory gaint TARTs. And presence of tunica vaginalis cavity may indicate the severity of TARTs in surgery.

Project description:ObjectiveTo analyze the mutational spectrum, clinical characteristics, genotype-phenotype correlations, testicular adrenal rests tumor prevalence, and role of neonatal screening in congenital adrenal hyperplasia (CAH) patients from Slovakia and Slovenia.Design and methodsData were obtained from 104 patients with CAH registered in Slovak and Slovenian databases. Low-resolution genotyping was performed to detect the most common point mutations. To detect deletions, conversions, point mutations, or other sequence changes in the CYP21A2 gene, high-resolution genotyping was performed. Genotypes were classified according to residual 21-hydroxylase activity (null, A, B, C).Results64% of the individuals had the salt-wasting form (SW-CAH), 15% the simple virilizing form (SV-CAH), and 21% the non-classic (NC-CAH). CYP21A2 gene deletion/conversion and c.293-13A/C>G pathogenic variant accounted together for 55.5% of the affected alleles. In SV-CAH p.Ile172Asn was the most common pathogenic variant (28.13%), while in NC-CAH p.Val282Leu (33.33%), CYP21A2 gene deletion/conversion (21.43%), c.293-13A/C>G (14.29%), Pro30Leu (11.90%). The frequency of alleles with multiple pathogenic variants was higher in Slovenian patients (15.83% of all alleles). Severe genotypes (0 and A) correlated well with the expected phenotype (SW in 94.74% and 97.3%), while less severe genotypes (B and C) correlated weaklier (SV in 50% and NC in 70.8%). The median age of SW-CAH patients at the time of diagnosis was 6 days in Slovakia vs. 28.5 days in Slovenia (p=0.01). Most of the Slovak patients in the cohort were detected by NBS. (24 out of 29). TARTs were identified in 7 out of 24 male patients, of whom all (100%) had SW-CAH and all had poor hormonal control. The median age at the diagnosis of TARTs was 13 years.ConclusionThe study confirmed the importance of neonatal screening, especially in the speed of diagnosis of severe forms of CAH. The prediction of the 21-OH deficiency phenotype was reasonably good in the case of severe pathogenic variants, but less reliable in the case of milder pathogenic variants, which is consistent compared to data from other populations. Screening for TARTs should be realized in all male patients with CAH, since there is possible remission when identified early.
