LEUKOCYTIC "INCLUSION BODIES" WITH SPECIAL REFERENCE TO SCARLET FEVER
Archives of Pediatrics & Adolescent Medicine
D\l=o"\hle1 described certain "bodies" within the cytoplasm of the polymorphonuclear leukocytes in blood smears from thirty patients with scarlet fever. In a number of controls similar "bodies" were found in a patient with pneumonia and two patients with malignant neoplasms. As far as he knew these "bodies" had not been described before and to them the term "inclusion bodies" (Leukocytenenschl\l=u"\sse) was applied. In March, 1912, Kretschmer2 confirmed these findings and considered their
... ce in scarlet fever of diagnostic value. The latter also found these "bodies" in smears from patients with pneumonia and tuberculosis and two with diphtheria with streptococcus empyema. More recently Nicoll and Williams3 reported a study of fifty-one cases of scarlet fever, finding the "bodies" in forty-five cases. Similar "bodies" were found in three out of twenty-five controls. The presence of such "bodies" within the polymorphonuclear leukocytes of cases of scarlet fever are mainly of interest from the standpoint of differential diagnosis and of their possible relation to the etiology of this infection. Dohle suspected their relation to streptococcus infections and if these "bodies" are to be found in a large percentage of scarlet fever cases and are absent in non-scarlatinal conditions, they would be of considerable aid in differentiating true scarlet fever from cases of serum sickness with scarlatiniform rashes, rötheln, various toxic erythemata, etc.
