Nonclassic congenital adrenal hyperplasia misdiagnosed as Turner syndrome

Nonclassic Congenital Adrenal Hyperplasia

PURPOSE OF REVIEW Late-onset or nonclassic congenital adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive disorders. Reported prevalence ranges from 1 in 30 to 1 in 1000. Affected individuals typically present due to signs and symptoms of androgen excess. The purpose of this review is to provide current information regarding the pathophysiol...

Glucocorticoid Deficiency Nonclassic Lipoid Congenital Adrenal Hyperplasia Masquerading as Familial

Nonclassic lipoid congenital adrenal hyperplasia masquerading as familial glucocorticoid deficiency.

CONTEXT Familial glucocorticoid deficiency (FGD) is an autosomal recessive disorder resulting from resistance to the action of ACTH on the adrenal cortex. Affected individuals are deficient in cortisol and, if untreated, are likely to succumb to hypoglycemia and/or overwhelming infection. Mutations of the ACTH receptor (MC2R) and the melanocortin 2 receptor accessory protein (MRAP), FGD types 1...

A Rare Combination: Congenital Adrenal Hyperplasia Due To 21 Hydroxylase Deficiency and Turner Syndrome

A combination of Turner syndrome (TS) and classical congenital adrenal hyperplasia (CAH) is rare. A one-day-old newborn was referred to our hospital with ambiguous genitalia. The parents were third-degree relatives. The infant's weight was 3350g (50-75p), and the head circumference was 34.5cm (50p). The gonads were nonpalpable. Presence of a 3 cm phallus, one urogenital opening into the perineu...

A girl with steroid cell ovarian tumor misdiagnosed as non-classical congenital adrenal hyperplasia.

Ovarian steroid cell tumors are rarely encountered in prepubertal girls. The majority of these tumors produce hormones, testosterone being the leading one. These tumors may either coexist with or imitate congenital adrenal hyperplasia (CAH). We present a 13-year-old female patient who was diagnosed with non-classical CAH at six years of age while being investigated for premature pubarche. She w...
