Hemophagocytic Lymphohistiocytosis is a condition in which often there is a diagnostic delay due to non-specific clinical manifestations. We recently had two cases of Lymphoma associated hemophagocytic syndrome(LAHS)- while one presented with hemophagocytic lymphohistiocytosis (HLH) the other case developed HLH after achieving a complete remission secondary to a complication of chemotherapy. The description of the cases is followed by relevant discussion of pertinent points. In this article, we want to highlight the importance of evaluating for a lymphoproliferative disorder in a case of HLH as well as considering HLH in patients with lymphoma who have unexplained constitutional symptoms and cytopenias.
