title: [Two cases of orbital non-Hodgkin's lymphoma presenting with hemophagocytic syndrome].
abstract: We report 2 cases of orbital non-Hodgkin's lymphoma (NHL) with hemophagocytic syndrome (HPS). Patient 1 was a 64-year-old man with a diagnosis of peripheral T-cell lymphoma originating in the right orbita (clinical stage: IV B). Epstein-Barr virus DNA was demonstrated in tissue specimens by polymerase chain reaction. Laboratory findings on admission were WBC: 4,700/microliter, Hb: 12.1 g/dl, Plt: 14.6 x 10(4)/microliter, LDH: 951 IU/l, sIL-2R: 2,553 IU/ml, and ferritin: 5998.1 ng/ml. Patient 2 was a 73-year-old man with a diagnosis of diffuse large B-cell lymphoma originating in the right orbita (Clinical stage: IV B). Laboratory findings on admission were WBC: 9,100/microliter, Hb: 7.7 g/dl, Plt: 15.4 x 10(4)/microliter, LDH: 1,043 IU/l, sIL-2R: 10,090 IU/ml, and ferritin: 2079.3 ng/ml. Both patients had high-grade fever and extremely high serum cytokine levels. Bone marrow aspiration disclosed many histiocytes with hemophagocytosis. In both cases, combined chemotherapy was transiently effective, but patient 1 died of relapse of HPS and patient 2 of cerebral bleeding. Orbital non-Hodgkin's lymphoma with HPS is rare. These cases were interesting in terms of the relationship between HPS and the primary site of lymphoma.
