Facial hair

Introduction Facial hairiness means that the hair density increases and becomes longer and longer. It exceeds the normal physiological range. Generally, the facial, genital, armpit, abdomen, back and limbs are obviously increased in growth and thickening, and some are long beards, chest hairs and nipples. Long hair, often accompanied by irregular menstruation, cold and so on. After entering adolescence, the girl gradually grows long hair, which is normal. But some young girls have long hairs on their arms, legs, face, back, and so on. The cause of hirsutism is due to the obstacles in the synthesis of female hormones in the body, abnormalities in the pituitary and ovarian function, hyperadrenal hyperfunction and other factors that produce excessive amounts of androgens such as androstenedione. Generally, the facial hair, genitals, underarms, abdomen, back and limbs are obviously increased in size and thickened and black.

Cause

In summary, the causes of hirsutism can be roughly divided into the following seven categories:

1. Congenital factors: It includes four factors: home hirsutism, premature development, male malformation and primary hirsutism. Primary hirsutism is caused by hair follicles allergic to endogenous androgens or increased dihydrohydrotestosterone in the periphery.

2. Cerebral and hypothalamic lesions, such as encephalitis caused by encephalitis, multiple sclerosis, and intracranial hyperplasia.

3. Pituitary hirsutism, such as acromegaly, diabetes, basophilic tumor (secondary hypercortisolism) may cause hirsutism.

4. A hirsutism caused by a younger type of hypothyroidism.

5. Adrenal glandular syndrome and hirsutism caused by hypercortisolism.

6. Menopausal or women with polycystic ovary or with follicular hyperplasia and ovarian tumors may have a lot of hair.

7. Because of the use of exogenous drugs (such as androgen, phenytoin, synthetic progesterone, cortisone), pregnancy, puberty caused by mental anorexia, mental stress or local irritation. Among the many causes, adrenal adenomas, ovarian tumors, polycystic ovary, follicular hyperplasia, and primary hirsutism are the most common.

Hair endocrine function test

The general manifestations of facial, genital, axillary, abdomen, back and limbs hair increased significantly increased and dark and black diagnosis ideas from the cause analysis, 46 kinds of hair abnormal diseases, congenital genetic factors 22, accounting for 48.88% . 23 acquired species, accounting for 51.12%. Among them, 6 kinds of endocrine, 3 groups of drugs (17 kinds of drugs), 4 kinds of acute and chronic diseases (19 kinds of diseases), physiological (one is pregnancy, one is senile), one kind of trauma, the cause is unknown 6 kinds. Therefore, acquired abnormal diseases, mainly: endocrine abnormalities, various acute and chronic disease groups, drug-induced, especially immunosuppressant anticancer drugs. These statistical analyses provide us with a clear diagnosis. Therefore, the history of the disease should focus on family history and genetic history. The history of medication, especially immunosuppressive drugs, should also be used as a key investigation and inquiry. As for acute and chronic diseases and infectious diseases, attention should be paid to systemic lupus erythematosus and scleroderma in leprosy, syphilis and connective tissue diseases. And jaundice, purulent sputum, and chronic wasting diseases.

Differential diagnosis

Differential diagnosis:

Excessive hair refers to an increase in body surface hair, and most have a history of excessive hair properties, and there is no masculine performance. Because there is no physiological abnormality, no treatment is needed.

A hirsutism refers to excessive growth of hair in some parts of a woman, usually in the upper and lower extremities and the face; the distribution form is male, and the hair is increased in the lower jaw, upper lip, front of the ear, forehead, and posterior neck, and the median line around the nipple and under the umbilicus. Both have been found to have relatively long hairs, and the distribution of pubic hairs is rhomboid, developing upwards and around the anus. Sometimes accompanied by masculinity, such as the appearance of a larynx, low tone and clitoris hypertrophy. In these cases, you should go to the hospital to check the cause, and then symptomatic treatment. The hirsutism is congenital and acquired, systemic and local. Systemic hirsutism, which belongs to the phenomenon of "returning to the ancestors", is caused by autosomal aberrations and has a tendency to inherit from generation to generation. Some also have a small cluster of long black hair on a part of the body surface, such as the spine. This is a congenital malformation such as spina bifida or meningocele. It is a local hirsutism. Cases of congenital hirsutism are rare and the diagnosis is relatively easy.
