ABSTRACT
OBJECTIVES: To assess the incidence of testicular adrenal rest tumors (TARTs) among male children with congenital adrenal hyperplasia (CAH) in tertiary care centers. METHODS: All male children aged 1-14 years diagnosed with CAH due to 21-hydroxylase deficiency (21 HOD), 11ß-hydroxylase deficiency, and 3ß-hydroxysteroid dehydrogenase deficiency, confirmed by biochemical and/or genetic testing, underwent scrotal ultrasound examination to identify TARTs. After receiving the diagnosed patients' data, patients' electronic medical records were accessed to collect demographic data and scrotal ultrasound results, along with growth parameters and specific biochemical test results within 2 months of the ultrasound. RESULTS: TARTs were observed in 5 (10.9%) of 46 male children with CAH. Four patients with positive findings had 21 HOD classical CAH with salt loss and one had 21 HOD simple virilizing classical CAH. All patients had poor compliance and stage 2 bilateral TARTs. Three TART-positive patients (60.0%) had high ACTH levels, 5 patients (100%) had elevated 17-OHP levels, and 5 patients (100%) had advanced bone age. The youngest patient with positive findings was 4 years old. CONCLUSIONS: The prevalence of TARTs increases with age and can be present in young males with classical CAH with 21 HOD. It is associated with elevated 17-hydroxyprogesterone (17-OHP) and advanced bone age SDS. TARTs are less likely to be associated with nonclassical CAH with 21 HOD or other less common CAHs due to 11ß-hydroxylase deficiencies and 3ß-hydroxysteroid dehydrogenase deficiencies in children. Our study recommends early and routine screening of TARTs in children with CAH.

Pseudohypoaldosteronism type 1 (PHA1) is an autosomal-recessive disorder characterized by defective regulation of body sodium (Na) levels. The abnormality results from mutations in the genes encoding subunits of the epithelial Na channel. Patients with PHA1 present in infancy as being in adrenal crisis. A 41-day-old female who presented with recurrent adrenal crisis did not adequately respond to hydrocortisone and required mineralocorticoid therapy. The patient's demographic data and clinical features were recorded. Blood samples were collected and tested for endocrine and metabolic characteristics and for use in genetic studies. Bidirectional Sanger sequencing of SCNN1A was conducted. The entire coding region of 12 exons and 20 bp of flanking intron were sequenced. Genetic analyses revealed a new mutation - c.729_730delAG (p.Val245Glyfs*65) - in SCNN1A exon four. Adrenal crisis during the neonatal period highlights the importance of early screening for PHA1. Genetic testing could help to anticipate the prognosis, severity, onset of the disease, and the mode of inheritance, especially given its extensive phenotype.
