Introduction: McCune–Albright syndrome (MAS) is a rare disease resulting from a somatic activating mutation of GNAS1 encoding the Gs-alfa subunit of the G-protein coupled membrane receptor responsible for multiple hormonal signaling cascades leading to the classical trias: polyostotic fibrous dysplasia, café-au-lait hyperpigmentation and GnRh independent precocious puberty. Early manifestation is accompanied with multiple organ involvement and may lead to ACTH-indepe...

Background: McCune–Albright syndrome (MAS) is a complex disorder characterized by the triad of fibrous dysplasia of multiple bones, café-au-lait skin macules and endocrinopathies.Objective and hypotheses: Long-term treatment of a boy with gigantism due to MAS.Method: Case report.Results: We present the clinical course of a now 14 years old boy with MAS and GH excess, clinical signs of precocious pub...

Background: McCune–Albright syndrome is a rare disorder defined as the triad of peripheral precocious puberty, café-au-lait skin pigmentation and fibrous dysplasia of bone, caused by mutation of the gene GNAS1, resulting in autonomous endocrine hormone excess.Objective and hypotheses: This is the first pediatric case of hirsutism due to tamoxifen, a selective estrogen receptor modulator.Case report: A 53/12 yea...

Background: McCune Albright syndrome (MAS) is defined by the classic triad of precocious puberty, fibrous dysplasia of bone and café au lait skin pigmentation. However, the clinical spectrum is often more variable due to mosaic distribution of the postzygotic GNAS-mutation. Hypercortisolism occurs in a minority (5%) of patients. It is most frequently caused by nodular adrenal hyperplasia and can be life-threatening. Decisions on whether clinical management should be conse...

Background: Hot thyroid nodules are uncommon in children and adolescents. Hyperfunctioning adenoma do not always produce hyperthyroidism, but can precede the apparition of a truly toxic adenoma. Autonomous adenoma can be associated with mutations of TSH-R and some mutations of GNAS.Patients: Patient 1 presented mild clinical hyperthyroidism. Patients 2 and 3 were asymptomatic and had clinical euthyroidism. Examination revealed a unique isolated thyroid n...

Case report: A 10-year-old Italian girl presented with a painless, hard swelling in left fronto-orbital region noted two years earlier. She had no headache or other symptoms; ophthalmologic evaluation revealed no signs of intracranial hypertension; the visual field showed a reduced level of sensitivity in the upper sector of the left eye.Her previous medical history was not relevant except for a mild head injury reported two years earlier. The girl was a secon...

Background: Mc Cune Albright (MAS), is a rare genetic disease clinically defined by bone fibrous dysplasia (BFD), café au lait skin spots and at least one hyperfunction endocrinopathy. Growth Hormone (GH) excess has been described in 20% of patients usually accompanied by hyperprolactinemia (80%). As reported in literature GH hypersecretion is allways associated with craniofacial BFD, macrocephaly and is also accompanied by higher risk of systemic...

Introduction: Neurofibromatosis type 1 (NF1) is an autosomal dominant multisystemic neurocutaneous disorder characterized by an increased risk of benign and malignant tumor formation (neurofibromas, glioma and gastrointestinal stromal tumor). The incidence has been described to be around 1 in 2,500–3,500 live births, and the estimated prevalence is 1 in 4,000–5,000. Although it was first described by von Recklinghausen in 1882, the formal diagnostic criteria were pub...

Background: Pituitary adenomas secreting GH rarely present in childhood. We report the clinical features, management and outcome of the 5 cases referred to a tertiary Paediatric Endocrine/Neurosurgical service over a 20-year period.Patients: **4 Male:1 Female - all aged 15 years at referral. Tanner puberty stages G3-5; B3. Clinical follow-up data range 2 months – 8 years.Clinical features at presentation: Headache, n=...

Background: Primary Ovarian Insufficiency (POI) and infertility are common concerns of female Childhood Cancer Survivors (CCS) and are known to impact their quality of life. Increased availability of fertility preservation techniques mandate a better understanding of risk factors for POI in this population.Objective and hypotheses: To describe the prevalence of and risk factors for POI in a cohort of adult CCS.Method: Cross-section...
