Jessner-Kanof disease: two effective and sure therapeutic options.

Jassner-Kanof disease is a benign cutaneous disorder clinically characterized by recurrent asymptomatic erythematous papules and plaques sometimes grouped with an arciform disposition on the face, neck, and back. We describe a case of Jassner-Kanof disease resistant to conventional therapy, in which the lesions located on the arms were treated with 595 nm pulsed dye laser, and those on the trunk underwent a treatment with tacrolimus 0.03% ointment. We have compared the results and the potential side effects with the two treatments, and after 1 year of follow-up, no recurrence of cutaneous lesions were observed.
