title: [T-cell rich B-cell lymphoma associated with hemophagocytic syndrome].
abstract: Report of a T-cell rich B-cell lymphoma (TCRBCL) in a 43 years old man with an associated haemophagocytic syndrome (HS). At presentation the haemophagocytic cells involved the same organs as the lymphoma, i.e. spleen, liver, abdominal lymph nodes and bone marrow. As supportive measure to alleviate chemotherapy-induced granulocytopenia the cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF) was given. After an initial improvement of the blood granulocyte count pancytopenia developed again, resulting in fatal sepsis. Autopsy demonstrated massive proliferation of macrophages in the bone marrow with haemophagocytosis as morphological correlation to the pancytopenia. The observation that exogenous GM-CSF enhanced the preexistent HS primarily reactive to the TCRBCL raises the question if endogenous GM-CSF may play a role in triggering a HS. The observed association of TCRBCL and HS has not been reported so far.
