Incontinentia pigmenti (IP) is a rare affection inherited as X-linked dominant disease. It is usually lethal in male infants. IP can affect ectodermal tissues such as the skin, teeth, eyes, bones, and the central nervous system. Skin lesions occur mostly during the neonatal period and are
Familial progressive hyper- and hypopigmentation (FPHH) is characterized by diffuse hyperpigmentation with variable intensity. Cafe'-au-lait macules and larger hypopigmented ash-leaf macules are also present. Herein, we reported a variant case of FPHH. The patient was a two-year-old Chinese girl
Familial glucocorticoid deficiency is a rare autosomal recessive disorder characterized by isolated glucocorticoid deficiency. Most patients are diagnosed following episodes of hypoglycemia or convulsion. We report the case of an infant with familial glucocorticoid deficiency who BACKGROUND
Familial glucocorticoid deficiency, or hereditary unresponsiveness to adrenocorticotropic hormone, is a rare autosomal recessive disease characterized by glucocorticoid deficiency in the absence of mineralocorticoid deficiency. It may present in infancy or early childhood with
Epidermal nevus syndrome is seldom encountered, and its association with hypermelanosis and the chronic syndrome of inappropriate antidiuretic hormone secretion (SIADH) has never been reported. A male neonate who developed intractable seizures and hyponatremia soon after birth is reported. He had
BACKGROUND
Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive potentially life-threatening condition, characterized by glucocorticoid deficiency, preserved aldosterone/renin secretion, and secondary rise in plasma adrenocorticotropic hormone level. This occurs due to either
Proteus syndrome (PS) is an extremely rare and complex disorder. Approximately 200 cases have been reported, and it seems to affect people of all ethnic and racial groups. PS is characterized by segmental overgrowth of multiple tissues and organs including vascular malformations, lipomatous
Allgrove syndrome (OMIM 231550) is a rare autosomal recessive disease characterized by non-CAH primary adrenal insufficiency (non-CAH PAI), alacrima, and achalasia. It is caused by mutations in the AAAS gene. The syndrome is also associated with variable progressive neurological Pallister-Killian syndrome (PKS) is a rare genetic developmental disorder characterized, by intellectual disability, seizures, streaks of hypo- or hyperpigmentation and characteristic dysmorphic features. PKS is characterized by the presence of cytogenetic abnormality in form of a supernumerary
Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disorder characterized by isolated glucocorticoid deficiency. Mutations in the ACTH receptor (melanocortin 2 receptor, MC2R) or the MC2R accessory protein (MRAP) cause FGD types 1 and 2, respectively. A 2-year-old adopted Chinese
Familial progressive hyper- and hypopigmentation (FPHH) is a rare genodermatosis characterized by multiple café au lait spots and hypopigmented ash-leaf macules intermingled with blotchy hyperpigmentation (1,2). Herein, we describe a Turkish FPHH patient with café-noir spots. A 16-year-old male
Familial glucocorticoid deficiency type 1 (FGD1) is an autosomal recessive disorder caused by mutations in the melanocortin 2 receptor (MC2R) gene, characterized by a low or undetectable serum cortisol level and a high adrenocorticotropic hormone (ACTH) level. Clinical manifestations include
In two neonate girls with vesicular skin lesions, incontinentia pigmenti (Bloch-Sulzberger syndrome) was diagnosed. This rare X-linked dominant ectodermal disease can cause abnormalities in several organ systems. Most prominent are the dermatological abnormalities, developing in 4 stages: the
X-linked dominant Conradi-Hunermann-Happle syndrome (CDPX2; MIM 302960) is a rare chondrodysplasia punctata primarily affecting females. CDPX2 is presumed lethal in males, although a few affected males have been reported. CDPX2 is a cholesterol biosynthetic disorder due to
