Diagnosis and differentiation of wheat dermatitis
The disease should be differentiated from contact dermatitis. The severity of the lesion is related to the strength of the sensitizer or stimulating substance, the length of the action, the size of the contact area, and the sensitivity of the body. The light part is only congested, and the boundary is clear reddish or bright red spots; in severe cases, there may be damage such as papules, blisters, bullous erosion and exudation; strong irritation may cause skin necrosis or ulceration; when the body is highly sensitive, Generalized the whole body. In addition to itching pain, a small number of patients may have systemic symptoms such as aversion to cold, fever, nausea, and vomiting. The disease is self-limiting, and after removing the cause, it can heal itself quickly. If the cause is not removed in time, causing the disease to prolong, it can be converted into chronic, similar to eczema-like dermatitis.
