Diagnosis
Diagnosis and identification of Rosary red moss
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
The disease should be differentiated from allergic dermatitis, which usually has a clear history of exposure to allergens. After exposure to certain stimulating factors (allergens) on the skin and mucous membranes, only a few people with specific allergies develop. It does not occur immediately after the first contact, and often the body is first sensitized after an incubation period of 4-20 days (average 7-8 days). If the substance is contacted again, it can be about 12 hours (generally no more than 72 hours). Dermatitis can occur. This type of allergic reaction is the most common in contact dermatitis. It can be identified according to pathological examination and clinical features.
