What does dermatitis have from skin symptom

First, dermatitis is a general term for skin inflammatory diseases caused by various internal and external infections or non infectious factors. It is not an independent disease, and its etiology and clinical manifestations are complex and diverse. Clinically, a specific dermatitis is defined as dermatitis according to the etiology, site of disease or other clinical features, such as contact dermatitis caused by contact with a substance, drug dermatitis caused by internal use, etc.

Second, the clinical manifestations of dermatitis and eczema are various, which can be divided into three kinds of lesions: acute, subacute and chronic. In acute stage, erythema, edema, papule, blister or exudation may occur. The pathological manifestations were edema between epidermal cells, spongy formation and blisters in the epidermis. In subacute stage, blisters, redness and exudation decreased, and scab and desquamation appeared.

Third: in the chronic stage, the skin is mainly hypertrophic and tannic, accompanied by pigmentation or hypopigmentation, histopathological epidermal thickening, spinous layer hypertrophy, dermal papillary lymphocyte infiltration. Some patients can coexist at the same time, and some dermatitis does not have to go through three stages. The above clinical stages do not indicate the etiology or pathogenesis, but according to the etiology, location and clinical characteristics, the dermatitis that can be classified and diagnosed can be called classified dermatitis, such as silting dermatitis and seborrheic dermatitis.
