Cutaneous vasculitis in non Hodgkin's lymphoma

Institute of Hematology, University of Catania, Italy.

Cutaneous vasculitis has been described in association with various hematological malignancies, but it seems to be very uncommon among non Hodgkin's lymphomas (NHL). For this reason no attention has been given to the peculiarity of this rare association. We identified 5 cases of cutaneous vasculitis among 315 NHL patients examined at our Institution from 1984 through 1990 and after the appearance of vasculitis, we observed some heterogeneity in either the degree of activity or in the clinical outcome of the NHL. The onset of cutaneous vasculitis appeared to mark two different clinical patterns: a vasculitis present from diagnosis characterized an indolent course of the neoplasia, while a late-appearing vasculitis was followed by rapid lymphoma progression and short survival.
