giant vagina
Introduction
Introduction When a baby boy is born, the penis is slightly larger than normal, but it is often unobtrusive. After half a year, the symptoms of precocious puberty gradually appear, which is more obvious when 4 to 5 years old. The main manifestation is that the penis rapidly increases, the scrotum and prostate enlarge, but the testicles do not increase relatively, and are commensurate with age, and there is no sperm formation, which is called premature giant yin.
Cause
Cause
Mainly due to defects in the enzymes necessary for the biosynthesis of adrenocortical hormones, resulting in abnormal cortical hormone synthesis. In most cases, the adrenal gland secretes glucosamine and physiochemical hormones and the male hormone is too much. Therefore, there are different degrees of adrenal insufficiency in the clinic, accompanied by masculinization of the girl, while the boy is sexually precocious, and there may be hyponatremia. Or a variety of syndromes such as high blood pressure.

The child has pubic hair very early, the skin is acne-prone, has a laryngeal knot, the voice becomes low, the muscles are developed, the body develops too fast, the body length exceeds the age of the child, and the epiphysis grows far beyond the age. If it is not diagnosed and treated correctly, the epiphysis will be prematurely integrated, and the body will be shorter when it is adult. Intelligence development is generally normal. The baby girl may have a clitoris hypertrophy at birth, and gradually enlarges like a boy's penis, but is thicker than the penis of the same age boy. The labia majora is like a boy's scrotum but no testicles (Fig. 2). During the embryonic period, due to the influence of excessive androgen, the normal development of female reproductive organs can be prevented. At the 12th week, the female external genitalia is formed, and the urethra is separated from the vaginal opening.
Diagnosis
Differential diagnosis
First, female children should pay attention to the identification of true hermaphroditism. The latter is a genital gland, ovary and testicular tissue in a human body, but it is underdeveloped, so its estrogen, androgen and urinary 17 ketone steroids are discharged. It is lower than normal.
Second, the girl's urethra, vaginal opening in the urogenital sinus, especially when the opening is located at the base of the clitoris, attention should be paid to the identification of the boy's hypospadias and cryptorchidism. Iodine oil can be used to observe the presence or absence of uterus, and can be used for chromosome examination. The sex chromatin of patients with adrenal hyperplasia is positive and the sex chromosome is female.
Third, patients with salt loss in the early post-natal vomiting, dehydration and other symptoms, should pay attention to pyloric stenosis and intestinal obstruction and other gastrointestinal diseases, especially in male children, such as rehydration and hyponatremia, high blood Potassium should not be corrected.
