title: Procainamide-induced SLE and lymphoreticular disorders.
abstract: A 56-year-old male patient diagnosed as a case of procainamide-induced systemic lupus erythematosus (SLE) was found to have a lymphoproliferative disorder at postmortem examination.Contrary to other immune disorders, the association of SLE with neoplasia is a rare occurrence. The present case raises the question of whether a relationship exists between the lupus diathesis and lymphoreticular neoplasia. The study of the incidence of neoplasia in families of patients with SLE may prove helpful in establishing this relationship.
