HYPERTRICHOSIS (syn.: Hairiness ) - excessive hair growth that is not characteristic of this area of the skin, does not correspond to gender and age. Clinically distinguish between congenital (general and limited) and acquired forms of hypertrichosis. A congenital form of general hypertrichosis, in which the entire surface of the skin is covered with long wavy hair, is a very rare abnormality that progresses to puberty.
With a congenital limited form of hypertrichosis, in some cases, excessive hair growth is observed on pigmented skin in the form of the so-called striped pigmented birthmarks, in others, on normally pigmented skin, usually in the sacral region (the so-called bundle of faun). The acquired form of hypertrichosis can occur in places of prolonged skin irritation (rubbing ointments, plaster dressings), in patients with tuberculosis, osteomyelitis. Sometimes in girls in the puberty period or in women in the menopause, enhanced growth of hair begins on the face, above the upper lip. In the pathogenesis of the acquired form of hypertrichosis, the main role is played by changes in the neuroendocrine system.
Congenital general form of hypertrichosis cannot be treated ; with a limited form, surgical intervention is sometimes possible. With hypertrichosis due to endocrine disorders, the underlying disease is treated. In most cases, hypertrichosis is carried out only by local treatment - the destruction of hair follicles using diathermocoagulation. For cosmetic purposes, bleaching hair, hair removal.
