The patient was a 13-year-old boy who was admitted because of fever, edema, cough, husky voice, generalized lymphadenopathy, hepatosplenomegaly and exanthema. Two months before the admission, he was noted the swelling of left axillar lymph node, which was removed and diagnosed as benign reticulosis histologically. His clinical signs mentioned above developed gradually during one and half months after the onset. On the admission, the laboratory examination revealed anemia, leukocytosis with abundant reticulum cell, hypocholesteremia, hypercupremia and dysproteinemia (increase of α1- and α2-globulin, decrease of Ig M). Against the administration of antibiotics and prednisolone, he was died of marked dyspnea apparently due to the infiltration of malignant reticulum cells on the tracheal mucosa.
