Prior to the findings of the hyperplasia of neuroendocrine cells it was known as tachypnea of infancy, as most children outgrow the need for oxygen supplementation within two to seven years. It is characterized by tachypnea, hypoxemia, and retractions. [1] It is typically diagnosed in infants and children younger than one year of age. [2]
Production of cortisol begins at week 8 of fetal life. [30] [31] [32] The 21-hydroxylase enzyme is essential in conversion of progesterone and 17OHP into 11-deoxycorticosterone and 11-deoxycortisol, respectively. [4] [33] This process is done through hydroxylation at C-21 position. [34]
Lipoid congenital adrenal hyperplasia is an endocrine disorder that is an uncommon and potentially lethal form of congenital adrenal hyperplasia (CAH). It arises from defects in the earliest stages of steroid hormone synthesis: the transport of cholesterol into the mitochondria and the conversion of cholesterol to pregnenolone—the first step in the synthesis of all steroid hormones.
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

Late onset congenital adrenal hyperplasia (LOCAH), also known as nonclassic congenital adrenal hyperplasia (NCCAH or NCAH), is a milder form of congenital adrenal hyperplasia (CAH), [1] a group of autosomal recessive disorders characterized by impaired cortisol synthesis that leads to variable degrees of postnatal androgen excess.
Follicular hyperplasia is one of the most common types of benign lymphadenopathies. [1] It can be typically found in children and young adults however all ages are subject to follicular hyperplasia, including the elderly. Lymphadenopathies such as follicular hyperplasia, are usually localized but can also be generalized and are non gender specific.

Hyperplasia of the breast – "Hyperplastic" lesions of the breast include usual ductal hyperplasia, a focal expansion of the number of cells in a terminal breast duct, and atypical ductal hyperplasia, in which a more abnormal pattern of growth is seen, and which is associated with an increased risk of developing breast cancer.
