Vaccinia necrosum complicating immunoblastic sarcoma.
A 59-year-old man is presented who had immunoblastic lymphadenopathy which evolved over a three-year period into immunoblastic sarcoma. His course was complicated by vaccinia necrosum, which necessitated prolonged therapy with Marboran and vaccinia-immune globulin. The persistence of virus was documented at autopsy by positive viral culture and ultra-structural examination. This case illustrates the potential hazards of administration of live viral vaccines to an immune compromised host presumed to be in remission and suggests that the continued activity of viral infection may signal the unsuspected persistence of underlying disease.
