A 70-year-old man presented with six months of dyspnea on exertion, night sweats, and weight loss. He was found to be febrile and in distributive shock, with laboratory analysis demonstrating cytopenias, coagulopathy, and lactic acidosis. Computed tomography of the abdomen and pelvis was notable for hepatosplenomegaly, and a bone marrow biopsy revealed a monoclonal B-cell population with hemophagocytosis. The patient was diagnosed with diffuse large B-cell lymphoma complicated by hemophagocytic lymphohistiocytosis (HLH).
Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening, immune-mediated disease caused by impaired NK and cytotoxic T-cell function. While genetic defects play a prominent role in triggering HLH in children, most cases of HLH in adults are secondary to another disorder, such as infections (e.g., EBV, histoplasmosis), hematologic malignancies (e.g., NK, T, or B-cell lymphomas), or autoimmune disease (e.g., systemic lupus erythematosis).
