Internal factors such as chronic digestive system diseases, mental stress, insomnia, excessive fatigue, mood changes, endocrine disorders, infections, metabolic disorders, etc., and external factors such as living environment, climate change, food, etc. can all affect the occurrence of eczema. External stimuli such as sunlight, cold, dryness, heat, hot water washing, various animal furs, plants, cosmetics, soaps, artificial fibers, etc. can all induce it. It is a delayed allergic reaction caused by complex internal and external factors.

1. According to the manifestation of skin lesions, it is divided into three stages: acute, subacute and chronic.

(1) Acute eczema lesions initially appear as numerous densely packed millet-sized papules, papulovesicles or small blisters with a flushed base that gradually merge into patches. Due to scratching, the papules, papulovesicles or blisters may show obvious punctate exudation and small erosive surfaces with unclear edges after being scratched. If secondary infection occurs, the inflammation will be more obvious and may form pustules, pus scabs, folliculitis, furuncles, etc. Conscious severe itching. It often occurs on the head, face, behind the ears, distal limbs, scrotum, and perianal area, and is often distributed symmetrically.

(2) Subacute eczema After the inflammation of acute eczema is alleviated, the skin lesions are mainly small papules, scabs and scales, with only a small amount of papulovesicles and erosions. Still have severe itching.

(3) Chronic eczema often turns into chronic eczema due to repeated attacks of acute or subacute eczema; it may also start as chronic eczema. The symptoms include thickening and infiltration of the skin in the affected area, brown-red or pigmentation, rough surface, scaling, or scabs due to scratching. Conscious itching. It is commonly found in the calves, hands, feet, elbows, popliteal fossa, vulva, and anus. The course of the disease is uncertain, prone to relapse, and difficult to heal.
