increased hair
Introduction
Introduction Hyperplasia and hirsutism are excessive hair in the body's non-androgen-dependent areas, which may be congenital or acquired, general or local. However, under normal circumstances, ethnic hairs may vary, not only in different colors, but also in different quantities. For example, Greek males have a lot of chest hair, while Chinese men have fewer chest hairs. Unlike hairy hyperplasia, hirsutism refers to excessive hairiness in females, which occurs only in the androgen-dependent parts, and the slender bristles become thick and short hairs. Female hair is too much, with masculine performance, affecting the appearance.
Cause
Cause
Common causes of hirsutism are: idiopathic hirsutism, polycystic ovary syndrome (polycystic ovary syndrome is an internal sputum disorder affecting nearly one percent of women worldwide. Symptoms include menstrual sparse or cessation, chronic anovulation Infertility, hairy and hemorrhoids, etc. The patient's ovaries will be covered with tiny cysts, which in severe cases will proliferate the uterine wall and increase the risk of uterine cancer. Ovarian tumors, hypercortisolism, adrenal gland Abnormal symptoms, application of diazoxide, phenytoin, androgen.

The increase in the number of female hair, quality and distribution changes are male characteristics, such as the appearance of whiskers, thick eyebrows, and the androgen in the neck, chest and back, lower abdomen, perineum, forearm, thigh, etc. (androgen is the epididymis structure, functional influence The most hormonal hormone. The concentration of androgen in the epididymis is high, which is mainly caused by the testicular fluid and blood circulation.
Diagnosis
Differential diagnosis
(1) Congenital fetusesis: This disease is also known as congenital systemic hirsutism. It is found in children under 10 years old. It has excessive hair on the body and face. It is filamentous and may be accompanied by abnormal tooth development. It is a rare disease. Autosomal dominant inheritance. Such children are commonly known as "hair boy", "dog face child" or "wolf man", and have been reported at home and abroad. The patient's fetal hair persists and is not replaced by terminal hair.
(2) Acquired polypsils: This disease is less common than congenital, more women than men, sudden increase of filamentous hair throughout the body, or limited to local, rapid hair growth, 2.5cm per week, length up to 10 cm the above. More often combined with malignant tumors, often breast, lung, gallbladder, pancreas, colon, rectum, bladder, ovary or uterine cancer. When the tumor is removed, the increase in hair can be reduced.
(3) Congenital local hair hyperplasia: The disease occurs at or after birth, there is no need for a good hair, hairy skin with or without sputum. Often associated with some sputum, known as sputum-like hair hyperplasia, such as Becker , thick and long hair. Spina bifida and tibial hair hyperplasia are seen in children, with a cluster of thick or fine hairs with spina bifida in the lumbosacral region.
Finger hyperplasia is more common in men, occurring on the dorsal side of the 2nd, 3rd, 4th, and 5th fingers (toe) and is autosomal dominant. Elbow hyperplasia, also known as multiple elbow syndrome, is a hairy elbow after birth. After 5 years of age, hairy hair begins to decrease, which can be autosomal dominant or recessive. Hair ears, also known as hairy ears, mainly occur in men. The short hairs of the external auditory canal become thick and long, extending out of the ear wheel, which is autosomal dominant.
(4) Acquired local hyperplasia: often occurs after skin inflammation or chronic irritation, such as friction, bites, vascular obstruction, arthritis, mucus edema of the axilla, varicose veins of the lower extremities or eczema.
(5) iatrogenic hairy hyperplasia: long-term application of certain drugs can cause hairy, found in the trunk, limbs, and occasionally on the face. The hair has a diameter between the baby's hair and the terminal hair and can be as long as 3 cm. Generally, after half a year to one year, the hair can be recovered. Common drugs are phenytoin, streptomycin, prednisone, penicillamine, psoralen, minoxidil and the like.
The increase in the number of female hair, quality and distribution changes are male characteristics, such as the appearance of whiskers, thick eyebrows, increased hair in the neck area, chest and back, lower abdomen, perineum, forearms, thighs and other areas sensitive to androgen response.
