—We read with interest the letter to the editor concerning splenic abscess in infectious endocarditis published in the February Archives.1 The authors reemphasized an important point: the frequency of splenic abscess is often underestimated in patients with infectious endocarditis. In the autopsy series of 78 patients described in this letter, the incidence of splenic abscess was 6.4%. Unfortunately, the authors did not indicate over what time period these 78 patients expired.
