ALK-Positive Anaplastic Large Cell Lymphoma Associated With Hemophagocytic Lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) has been rarely reported as a complication of anaplastic large cell lymphoma (ALCL), especially in the adult population. We herein present a case of a young woman who presented with multiorgan failure and disseminated intravascular hemolysis and was later found to have ALCL-associated HLH. We also review the current literature on ALCL-associated HLH in adult patients, with their respective treatments and outcomes. We discuss the challenges associated with the diagnosis of lymphoma in the setting of HLH and multiorgan failure. Further, given its high mortality rates, we highlight the importance of promptly identifying and treating the underlying etiology of HLH.
