SUMMARY
The bone marrow of a 69-year-old female patient, post-allogeneic stem cell transplantation, exhibited extensive hemophagocytosis in follow up. The extent of hemophagocytosis prompted investigation for hemophagocytic lymphohistiocytosis (HLH). While the diagnosis was not straightforward, clinical and biochemical features were consistent with HLH, and in this case more specific with post-transplantation HLH, a rare form of secondary HLH.
