Background: Hyperinsulinemic hypoglycemia is a heterogeneous condition characterized by inappropriate insulin secretion in the presence of low blood glucose levels. It can have various causes, including genetic, metabolic, syndromic, autoimmune, insulinoma, non-insulinoma pancreatogenous hypoglycemia or non-islet cell tumor hypoglycemia. On the other hand, oculofaciocardiodental syndrome is a rare X-linked dominant condition characterized by multiple congenita...

Background: POR deficiency is a rare form of congenital adrenal hyperplasia, transmitted in an autosomal recessive trait, that is characterized by ambiguous genitalia, impaired steroidogenesis and skeletal malformations similar to those of Antley-Bixler syndrome. It is caused by mutations in the P450 oxidoreductase gene (POR), an electron donor for all microsomal P450 enzymes including the three steroidogenic enzymes P450c 17 (17 alfa-hidroxylase /17,20 lyase)...

Pulmonary carcinoid tumors represent well-differentiated pulmonary neuroendocrine tumors, which include typical and atypical carcinoids. This type of lung tumors is rare, but represents the most common primary malignant lung tumor in children and adolescents, especially the typical carcinoids. They can be asymptomatic at the time of diagnosis or can present with nonspecific findings like recurrent pneumonia, cough, and hemoptysis. We report the case of a 15-year-old girl reffe...

Background: Childhood hematologic malignancies are no longer a death sentence. With survival rates significantly increasing, focus needs to shift towards diminishing long-term adverse effects, such as bone disorders. In childhood hematologic cancer survivors (CHCS), peak bone mass is not usually attained due to malginancy-related inflammation, treatments employed or subsequent endocrine complications. Thus, low BMD is frequent. However, in the absence of fragi...

Introduction: Papillary thyroid carcinoma (PTC) in the pediatric and young adult population presents contradictory features: it shows higher rates of multifocal disease, local and distant metastasis, and recurrence compared to adults, yet the overall 5-year survival rate remains exceptionally high at 98-100%. In children, RET/PTC rearrangements are the major somatic genetic alterations that drive the formation of PTC. On the other hand, mutations in <...

Background: Endocrine disturbances are the most prevalent complications in childhood cancer survivors (CSS), especially in those treated with cranial and cervical radiation for brain tumours, such as medulloblastoma. Recent data have shown frequent delays in the diagnosis and treatment of these complications that may lead to potential side-effects on general health. Apart from the well-known hypothalamic–pituitary and growth disorders observed in CSS, th...

We present the cases of a 3 yo girl diagnosed with precoccious puberty, with a personal history of premature telarchy, genital hair development and vaginal blood discharge at 1yo 2mo, currently in treatment with GnRH agonist, and the case of her younger sister, aged 1 yo, who also presented with premature telarchy. They have 2 older siblings, both of them are clinically healthy boys. Their mother and paternal aunt had normal pubertal development. No other history from females ...

Introduction: Persistent Müllerian duct syndrome (PMDS) is a rare disorder of sex development (DSD) characterized by the persistence of Müllerian derivatives, the uterus and/or fallopian tubes, in otherwise normally virilized boys. PMDS is caused by mutations in the genes coding anti-Müllerian hormone (AMH, PMDS type 1) or the AMH receptor (AMHR2 gene, PMDS type 2) and it usually presents as undescended testes (cryptorchidism) or inguinal hernia...
