Background: Adrenocortical Tumors (ACT) is a rare endocrine malignancy with heterogeneous presentation.Aim: To evaluate the clinical, biochemical and pathologic characteristics of pediatric ACT in a single tertiary center.Subjects and methods: Review of 28 medical records with childhood ACT (chronological age (CA) <18 years (y) treated between 1987 and 2017. Clinical, biochemical, and histological features (Wieneke index), stag...

Disorders of sex development (DSD) are those congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. The aim of this study was to characterize the histology of 46,XX DSD prepubertal gonads. We studied 25 gonads of fourteen 46,XX DSD patients. The age of biopsy/gonadectomy was 1.17 (0.08–4.17) years (median and range). Molecular studies confirmed the absence of SRY by PCR and/or MLPA in blood samples of all patients and i...

Background: The SRY protein is a transcription factor that contains a high mobility group (HMG) homeobox domain which possesses sequence-specific DNA binding activity and regulates other genes involved in male sex determination pathway. The majority of the identified mutations occurred within the HMG-box motif. There are few reports of pedigrees with familial transmission.Objective and Hypotheses: To describe a paternally transmitted novel SRY mutation w...

Background: Wilms' Tumor Suppressor Gene 1 (WT1) plays an essential role in urogenital and kidney development. Germline variants in WT1 are associated with life-threatening glomerulopathy, disorders of gonadal development in both 46,XY and 46,XX individuals, Wilms tumor, and gonadal malignancies. Phenotypic overlap among 46,XY affected subjects has been frequently observed and there is still scarce information regarding renal involvement...
