Atypical hemophagocytic lymphohistiocytosis following bacterial tonsillitis in acute lymphoblastic leukemia.
We report a rare case of a cute lymphoblasticleukemia (ALL) who developed dyspnea, neurological disturbance with illusions, pancytopenia, phagocytosis and coagulation disturbances following bacterial tonsillitis. The values of soluble interleukin-2 receptor (sIL-2R), IL-6 and IL-8 were also elevated. Her clinicolaboratory findings were similar to hemophagocytic lymphohistiocytosis (HLH), which is a cytokine disease induced by activated T cells and macrophages. Atypical HLH following bacterial tonsillitis should be kept in mind in leukemia patients.
