title: [T gamma lymphoma with CD3+ CD4- CD8- WT31- and TcR gamma delta].
abstract: An 18 years old female was admitted to hospital due to pancytopenia on May 25, 1987 and found to have petechiae, mild hepatomegaly and severe splenomegaly. The bone marrow was found to contain 12% of blast cells. Splenectomy was performed followed by CHOP therapy. In September, 1987 the peripheral blood was found to contain tumor cells, which turned out to be resistant to various combination chemotherapies. The patient died on August 21, 1988. The phenotype of tumor cells in this case was CD2+ CD7+ CD3+ CD4- CD8- WT31-. Genetic analysis detected rearrangement of the beta and gamma chain of TcR but not transcription or translation of the beta chain of TcR, while the antibodies of delta TCS 1 and TcR delta 1 to the delta chain of TcR were positive. From this fact, the present case was considered to be the malignant counterpart of normal CD3+ WT31- double negative T cells. The reactivity of this tumor cells to IL-2 and IL-1 beta suggested the association of the IL-2R beta chain.
