Definition and epidemiology
Excessive hair growth on sites are not normally hairy.
A relatively common disorder.
More common in females.
may be familiar or part of congenital disorder.
Most cases are acquired.
They may be idiopathic, or due to:
– metabolic disorders, such as underlying cancer.
– endocring disorders, such as Grave’s disease or polycystic ovarian syndrome;
– nutritional disorder, such as anorexia nervosa;
– iatrogenic caused, such as corticosteroid, cyclosporin A or phenytoin.
Excessive hair growth, which may be lango or vellus type.
The process does not seem to be androgen-dependant.
May be localised or generalised.
Common sites for localised excessive hair growth include the ears (particularly in male Asians) and eyebrows.
Localised hair growth may occur in people with melanocytic naevi ir undrlying disease, for example, the faun tail in people with spina bifida.
A generalised male pattern of hair growth may occur in women (sometimes known as hirsutism).
Latrigenic hair growth is often generalised.
Shaving and hair removal creams usually suffice with mild to moderate disease.
Electrolysis and diathermy permanently destroys hair follicies.
Anti – androgen drugs help in severe disease.
Refer patients if you suspect an underlying congenital or impotant acquired condition.
Be alert to psychological morbidity as a consequence of hypertrichosis.
