In recent years it has become apparent that a minor proportion of malignant lymphomas express a natural killer (NK) cell phenotype defined by their reactivity with the CD56 antibody. A significant proportion of these lymphomas present with cutaneous infiltrations and seem to follow an aggressive clinical course.1 We describe a patient with a cutaneous NK/T-cell lymphoma confined to the skin that showed an indolent course after local radiation therapy.
