Introduction: Central diabetes insipidus (CDI) is a condition in which large volumes of diluted urine are excreted due to vasopressin deficiency. In most patients, DI is caused by the destruction of neurons in the hypothalamus and the known causes include local inflammation or autoimmune aggression, vascular and infiltrative diseases, as well as compressive masses, trauma or midline cranial malformations. CDI caused by cytomegalovirus (CMV) infection is a very rare condition.<...

Background: A 5 years and 10 months boy presented with pubic hair, recent penile growth, aggressive behaviour and rapid growth of height. Antenatal, perinatal, and developmental history was unremarkable. There was no family history of precocious puberty. His height and weight were 128 cm (2.24 S.D.) and 25 kg (1.55 S.D.) respectively. Vital signs were normal. He was Tanner 2 for pubic hair and his stretched penis length was 11 cm, right testis vol...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Background: Androgen insensitivity syndrome (AIS) is the most common cause of 46,XY sexual differentiation disorders. Clinical presentation is variable among cases with a range from a complete female to male external genitalia. There is a weak correlation between genotype and phenotype.Aım: Our aim is to report clinical and molecular characteristics of siblings with AIS.Patients and methods: Two siblings newborns with ambiguou...

Background: There are two main problems that should be solved when encountering adrenal incidentaloma. The first of these is to decide whether the adrenal mass is benign or malignant and the second is to determine whether the mass is hormonally active or not.Objective and hypotheses: We aimed to focus on the approach to adrenal masses in childhood.Method: A case of phaeochromocytoma, which was diagnosed as incidentaloma is presente...

Background: Synchronous, multiple central nervous system (CNS) tumors are usually rare in pediatric patients. Pilocytic astrocytomas are the major type of CNS tumors in neurofibromatosis type 1 (NF1).Case presentation: A 6.5-year-old boy was admitted to our hospital for severe emaciation. Profound fat and muscle wasting were the only prominent clinical features. His growth rate was preserved despite his rapid dramatic weight loss (HT: 118 cm, P....

Background: Pre-pubertal gynecomastia is characterized by the presence of palpable breast tissue in boys in the absence of signs of sexual maturation. Gynecomastia is common in normal males in the neonatal period, at early puberty, and with increasing age and pre-pubertal gynecomastia is a rare condition and can be associated with excessive aromatase activity or oestrogen-producing adrenal or testicular tumours.Case Presentation: A 3-year-old presented w...

Background: Partial Androgen Insensitivity Syndrome (PAIS) is characterized by varying degrees of masculinization defects due to impaired androgen action, resulting in a wide range of physical and psychological phenotypes.Case 1: 18-year-old with a male social gender. The patient presented with hypospadias, micropenis, and cryptorchidism during the neonatal period, and received testosterone therapy during infancy, but sh...

Background: Carney complex (CNC) is a rare autosomal dominant multiple endocrine neoplasia and lentiginosis syndrome, characterized by abnormal cutaneous and mucosal pigmentation, myxomas of the heart, skin, breast and other non-endocrine tumors. CNC is principally caused by loss-of-function mutations of PRKAR1A gene located at 17q22-24 coding for the regulatory subunit type I alpha of protein kinase A (PKA) gene. Cushing’s syndrome is a rare disorder in...

Background: The definition of Cushing disease (CD) is hypercortisolism caused by excess adrenocorticotropic hormone (ACTH) secretion by a pituitary corticotrope adenoma. It is extremely rare in the pediatric population and requires rapid diagnosis and early management.Case presentation: A 14-year old boy was hospitalized because of sudden onset of chest pain, loss of consciousness, elevated cardio-specific enzymes, and s...
