After treatment, you should take anti-inflammatory drugs and transfer factor oral solution to avoid recurrence. . .

Flat warts: The cause is the same as that of filiform warts, but the structure and treatment principles are completely different. Moreover, traumatic treatment is prohibited for flat warts, otherwise it will lead to an outbreak of flat warts. . .

Neurodermatitis: This disease is a skin sensitivity disease caused by autonomic nervous system dysfunction. The patient's skin is itchy and the more it is scratched, the more itchy it becomes - the more itchy the more it scratches, the more itchy it becomes. The treatment of neurodermatitis is mainly based on Chinese medicine. . .

Photosensitive dermatitis: This disease is most common in summer, and its most characteristic feature is that it gets worse after sun exposure. In some specific cases, photosensitive dermatitis and neurodermatitis exist at the same time. In addition to taking Chinese medicine for the treatment of this disease, you should also avoid certain foods: fish, shrimp, crab, celery, coriander, etc. are the culprits of photosensitive dermatitis. .

Clinical manifestations of dermatitis

The clinical manifestations of dermatitis and eczema are diverse and can usually be divided into three types of skin lesions: acute, subacute and chronic.

1. Acute phase

It manifests as erythema and edema, which may be accompanied by papules, papular rashes, blisters or erosions and exudation. The center of the lesion is often heavier and gradually spreads to the periphery. The pathological manifestations are edema between epidermal cells, sponge formation, and blisters within the epidermis.

2. Subacute stage

Blisters, redness, swelling and exudation decrease, and crusting and desquamation appear.

3. Chronic stage

The skin is mainly rough, thickened and leathery, with moss-like changes, which may be accompanied by pigmentation or hypopigmentation. Histopathologically, the epidermis is thickened, the acanthus layer is thickened, and there is lymphocytic infiltration of the dermal papillae. Hand and foot eczema may be accompanied by nail changes. The rash is generally distributed symmetrically and often recurs. The subjective symptoms are itching, even severe itching.

There is often no clear boundary between the three stages mentioned above. Some patients may experience all three stages at the same time, and some dermatitis does not necessarily have to go through all three stages. The above clinical staging does not indicate the cause or pathogenesis. Based on the cause, site of onset and clinical characteristics, dermatitis that can be classified and diagnosed can be called classified dermatitis (eczema), such as congestive dermatitis, seborrheic dermatitis, etc.; those that have the clinical characteristics of dermatitis and eczema but cannot be further classified are called unclassified eczema (Table 1). Different types of dermatitis and eczema have relatively specific clinical characteristics.
