Pregnant woman itchy calf
Introduction
Introduction Pregnant women with leg itch often appear in the second trimester. The main symptom of this disease is itching. It starts from the limbs, especially in the chest, abdomen and lower limbs. Some pregnant women have jaundice, yellow eyes or skin, nausea, vomiting, poor appetite, etc., which have a greater impact on the fetus, leading to a significant increase in fetal mortality and must be treated. Severe rash will also appear - red pimples, due to severe itch, often scratched, bleeding bleeding, scarring, called pregnancy pruritus.
Cause
Cause
The cause of this is aggravation of liver burden, cholestasis, and decreased rate of bile acid excretion in pregnant women during pregnancy. The cause of this disease is unclear, but it is more prone to autoimmune diseases. There is information that the skin sensitivity of pregnant women with pruritus is often higher than that of pregnant women without pruritus, and it is not uncommon for people with allergic diseases such as urticaria and asthma. The skin scratch test is positive, the eosinophils in the blood are increased, and the pregnancy is increased. Increased chorionic gonadotropin, sensitivity to pregnancy metabolites may be a causative factor; some scholars believe that pruritus is a non-exudative variant of gestational herpes, which needs further confirmation.

Fungal histopathology
Cholyglycine (CG) is one of the combined bile acids bound to bile acid and glycine. Its content changes have important value in the diagnosis and treatment of liver diseases.
1. Seen by the naked eye: symmetric distribution, mung bean size, rounded top slightly flat, solid papules. There is a wind group between the papules, which scratches the surface and forms bloody scars. After the skin peels off, the skin rash subsides, and the local pigmentation or pigment disappears.
2. Histopathological changes of skin: no specificity, early papules are mild hyperepithelial layer hyperplasia, focal sponge formation in the epidermis, occasional small blisters and keratosis. Mild lymphocytic infiltration around the superficial blood vessels of the dermis, sometimes with a small amount of eosinophils and dermal papillary edema. A papule with epidermal exfoliation is characterized by partial epidermal loss and overlying sputum containing degenerating inflammatory nuclei. If serial sections are taken, cytological changes centered on hair follicles can be seen, which is characterized by the formation of a sponge, infiltration of monocytes at the opening of the hair follicle to the sebaceous gland, and inflammatory cell infiltration around the hair follicle.
