Remission of natural-killer cell lymphoma of the liver with anti-hepatitis C therapy.

Non-Hodgkin lymphomas (NHL) consist of a diverse group of lymphoproliferative neoplasms with unique patterns of biology, behavior, and differing responses to therapy. A rare subtype of malignancy arising from cells of putative natural killer (NK) origin is being recognized as a distinct clinicopathological entity. Viruses including hepatitis C have been reported in association with various types of NHL but not the NK-cell subtype. We hereby report a unique case of a patient with hepatitis C who developed hepatic NK-cell lymphoma and chronic NK-cell leukemia. Interestingly, we observed clinical and radiologic remission of the neoplasm following treatment with anti-hepatitis C therapy.

Granulocytic sarcoma presenting with malignant anasarca in a patient with secondary acute myeloid leukemia.

Granulocytic sarcomas (GS) are rare extramedullary tumor masses composed of immature cells derived from the hematopoietic myeloid series. GS occur in 3% to 7% of cases of acute myeloid leukemia (AML) and can present before, during, or even after the diagnosis of AML. GS can involve different organs, individually or simultaneously, including the skin, lymph nodes, bone, breast, central nervous system, and lung among others. GS involving peritoneal and pleural fluids is a rare presentation. We present an unusual case of a patient with myelodysplastic syndrome whose disease progressed into a secondary AML and developed GS in the ascitic and pleural effusions as the predominant manifestation of disease progression.
