| Abstract: | A patient with immunoblastic lymphadenopathy and features of Sj?gren's syndrome and systemic lupus erythematosus is presented. Clinical features included generalized lymphadenopathy, rash, alopecia, and synovitis, with associated laboratory abnormalities of a positive antinuclear factor and double-stranded DNA antibodies, positive lupus band test, and hemolytic anemia. Symptoms of Sj?gren's syndrome included dry eyes and mouth and swollen parotid gland; biopsy results of the accessory salivary glands were positive. At autopsy immunoblastic sarcoma was found that involved the myocardium, which stained for both kappa and lambda light chains by immunoperoxidase techniques. |
