ABSTRACT

Primary myelofibrosis (PMF) is a disease that affects the bone marrow. It presents with cytopenias, hepatospleomegaly accompanied with extramedullary hematopoiesis, and often with constitutional symptoms. Cytotoxic gamma-delta T-cells are considered a distinct hepatosplenic lymohoma. This is a case presentation of a 43-year-old male with an initial diagnosis of PMF who underwent allogeneic stem cell transplantation complicated by primary graft failure. He subsequently underwent a partial splenic


embolization; however, he quickly developed a fulminant hepatosplenic gamma-delta T-cell lymphoma which led to his death that was diagnosed posthumously. PMF has been known to transform into an acute myeloid leukemia, but there has been no established link with gamma-delta T-cell lymphoma.
