  Hyperplasia - Wikipedia, the free encyclopedia
Hyperplasia (or "hypergenesis") is a general term for an increase in the number of the cells of an organ or tissue causing it to increase in size.
Hyperplasia may be harmless and occur as a result of increased demand on a particular tissue.
Hyperplasia may also be induced artifically by injecting hormones such as IGF-1 and human growth hormone Perhaps the most interesting and potent effect IGF has on the human body is its ability to cause hyperplasia, which is an actual splitting of cells.

The dictionary defines hyperplasia as from the latin plasia meaning growth: A nontumorous increase in the number of cells in an organ or tissue with consequent enlargement of the affected part.
We have no ethical way of proving hyperplasia in vivo because the repeated removal of cells from the same subject on a recurring basis would be invasive and destructive of that individuals healthy muscle function.
We are left to prove myofibril hyperplasia indirectly.

 Congenital adrenal hyperplasia - Wikipedia, the free encyclopedia
Congenital adrenal hyperplasia (CAH) refers to any of several autosomal recessive diseases resulting from defects in steps of the synthesis of cortisol from cholesterol by the adrenal glands.
In all its forms, congenital adrenal hyperplasia due to 21-hydroxylase deficiency accounts for about 95% of diagnosed cases of CAH.
Congenital adrenal hyperplasia, which also dates to the first half of the century, has become the preferred term to reduce ambiguity and to emphasize the underlying pathophysiology of the disorders.

 Types of Hyperplasia
The most current research indicates that two key factors are the most meaningful: 1) whether the hyperplasia is “simple” or “complex,” and 2) whether “atypical cells” (also called “atypia”) are present in the endometrium.
In complex hyperplasia without atypia, the individual cells may be enlarged, but, as in simple hyperplasia, the internal makeup of the cells is considered to be normal.
Even when hyperplasia does lead to cancer, there is good news, which is that endometrial cancer is slow to grow and spread, and almost always shows itself early as non-menstrual bleeding, which is also the chief symptom of hyperplasia.

Benign prostatic hyperplasia is a term for non-cancerous enlargement of the prostate, the walnut-size gland located at the base of the urinary bladder in men.
The role of the prostate is to produce fluids found in semen, and as such the gland is closely associated with the urethra, the duct through which urine (and semen) flows for discharge at the glans of the penis.

 Focal epithelial hyperplasia
Focal epithelial hyperplasia is essentially an oral infection with the wart-producing papillomavirus, although from a different family of viruses.
Focal epithelial hyperplasia is somewhat different from other HPV infections in that it is able to produce extreme acanthosis or hyperplasia of the prickle cell layer of the epithelium with minimal production of surface projections or induction of connective tissue proliferation.
The sessile nature of focal epithelial hyperplasia also serves to separate it from the former two lesions, although this is not a guaranteed distinction.

 Endometrial Hyperplasia
Hyperplasia means "overgrowth," so endometrial hyperplasia means "overgrowth of, or too much, endometrium." Unless the lining of the uterus sheds regularly, tissues and glands will build up and may later become a breeding ground for abnormal cells.
Cystic glandular hyperplasia (also called cystic endometrial hyperplasia, or mild hyperplasia) means that you have too much lining but your endometrial cells are still normal, which is good news.
Although you might be more inclined to accept a recommendation of a hysterectomy for severe hyperplasia, this procedure is not necessary unless the hyperplasia persists after the lining is removed via progesterone supplements or D and C. In younger women particularly, severe hyperplasia can be reversed with hormonal therapy.

The phenotype can vary from clinically unapparent disease (occult or cryptic adrenal hyperplasia) to a mild form of disease, which is expressed in adolescence or adulthood (nonclassic adrenal hyperplasia), to severe disease resulting in adrenal insufficiency in infancy, with or without virilization and salt wasting (classic adrenal hyperplasia).
The goal of therapy of adrenal hyperplasia is the replacement of glucocorticoid and mineralocorticoid to prevent signs of adrenal insufficiency and to prevent the accumulation of precursor hormones that cause virilization.
Gender identity in females with virilizing adrenal hyperplasia is usually female provided the female gender assignment is made early in life, adequate medical and surgical support are provided, and the family and eventually the patient herself are provided with adequate education to understand the disease.

Parathyroid hyperplasia involves enlargement of all four parathyroid glands, which are located in the neck and control calcium metabolism.
Parathyroid hyperplasia causes about 15% of cases of hyperparathyroidism, which leads to elevated levels of calcium in the blood (hypercalcemia).
Parathyroid hyperplasia may occur sporadically (without a family history) or as part of three familial (inherited) syndromes: multiple endocrine neoplasia 1 (MEN 1) and MEN 2A and isolated familial hyperparathyroidism.

Background: Sebaceous hyperplasia is a common, benign condition of sebaceous glands in adults of middle age or older.
Sebaceous hyperplasia has also been linked to long-term immunosuppression in posttransplantation patients taking cyclosporin A. Although the mechanism for this reaction is poorly understood, this adverse effect is thought to be specific for the highly lipophilic cyclosporin A; other immunosuppressants have not been associated with an increased prevalence of sebaceous hyperplasia.
Causes: Sebaceous hyperplasia is thought to be caused by a decrease in the circulating levels of androgen associated with aging.

 Benign Prostatic Hyperplasia- Health Encyclopedia and Reference
The prostate is a male gland that secretes the fluid (a part of the semen) which carries sperm from the testicles during ejaculation.
It surrounds the first inch of the urethra (the tube through which urine and sperm exit the body).
Usually, the prostate gland starts to enlarge after middle age.When the prostate becomes enlarged, the condition is called benign prostatic hyperplasia (BPH), or benign prostatic hypertrophy.
