Abstract

According to the results of a study that involved 32 psoriatic patients, nevi with the diameter exceeding 5 mm are found in 68.8% of patients including 36% of patients with iatrogenic melanoma development risk factors (treatment with methotrexate and phototherapy), 50% of patients with anamnestic (burn injuries including vesication at the age below 18) and 4.5% of patients with inherited risk factors (melanoma in their relatives). As many as 32.4% of the nevi met the dysplastic nevi criteria in the course of the Pehamberger model analysis.
