The etiopathogenesis of the disease has not been exactly understood yet. Women and men are equally affected from psoriasis cases. One hundred forty-two male and one hundred twenty-one female with psoriasis patients were included in this study. The mean age of the male patients was 42.5 (min-max: 1-81) and the value was 37.9 (min-max: 2-82) for the female patients. The mean number of psoriasis cases in the spring was significantly higher than the value in the summer (p=0.044). Also, there was no significant seasonal difference between the mean numbers of the psoriasis cases (p>0.05). There was no statistically significant difference between the seasonal distribution and the number of psoriasis cases (p>0.05). For this reason, it can be said to be similar in number of psoriasis cases according to seasons. Finally, in this study has been concluded that the cases of psoriasis are more frequently observed in the spring and there is no gender difference in the psoriasis cases.trinfo:eu-repo/semantics/closedAccessPsoriasisSeasonGenderArticle728387N/A
