1. Heredity is a factor that causes psoriasis. According to the clinical seen, this disease often has family history, and have genetic tendency. Foreign countries have reported that people with family history of 30% to 50%, and even some individuals emphasize up to 100%. Domestic reports have a family history of about 10% to 20%, about the mode of inheritance, some people believe that the autosomal dominant inheritance, with incomplete epigenetic rate, and some people believe that the autosomal recessive inheritance or sex-linked inheritance. If one of the parents has psoriasis, the incidence of psoriasis in their offspring is three times higher than that of healthy children, and if both parents have psoriasis, the incidence of psoriasis in their offspring is even higher.

2. Infection. Clinical practice has proved that the onset of psoriasis is related to upper respiratory tract infections and tonsillitis. 6% of psoriasis patients have a history of pharyngeal infection. We found that many children's psoriasis is closely related to tonsillitis. For example, one mother and her three children had acute tonsillitis at the same time, and after the disease was controlled, psoriasis developed in three of them. This patient was effectively treated with antimicrobials. After removal of the tonsils, the rash can improve or subside significantly, indicating that infection is an important factor in the development of psoriasis.

3. Metabolic disorders. Research on blood chemistry, skin histochemistry and skin pathophysiology of psoriasis has failed to obtain useful results. In the past, it was thought that the onset of psoriasis is related to lipid metabolism disorders. This is also a factor that causes psoriasis.
