Peripheral-type natural killer ( NK)- or T-cell lymphomas are rare disorders characterized with clonal proliferation of mature lymphocytes. They have been linked to chronic and active Epstein-Barr virus infection (CAEBV), which itself is not defined as a malignant hematological disorder. The authors present a patient with T/NK-cell lymphoma involving skin, kidneys, spleen, pancreas, and meninges. She was remarkable for having the mosaic feature of more than one type of extranodal T/NK-cell lymphoma. She also had mixed findings of CAEBV that might have been attributed both to hypersensitivity to mosquito bites and to hemophagocytic lymphohistiocytosis.
