Abstract
Four cases of verruca vulgaris and 4 cases of molluscum contagiosum were treated by injection of methotrexate into the tumor itself. The concentration of 5 mg/ml of the drug had better effects than the more diluted solutions. Molluscum contagiosum disappeared within 2 or 3 weeks after the beginning of the treatment, and verruca vulgaris also disappeared within the same periods but required many more repeated injections. Except for the slight pain at the time of injection, there were no side effects during the treatment.
