Systemic lupus erythematosus is uncommon in elderly individuals. A 72-year-old woman developed parvovirus B19 infection followed by a systemic lupus erythematosus-like syndrome with persistent thrombocytopenia and Raynanud's phenomenon. Few cases of systemic lupus erythematosus after parvovirus B19 infection have been reported, and none had thrombocytopenia.
