The first infant case with hepatosplenic gammadelta T-cell lymphoma after acute disseminated encephalomyelitis (ADEM)-like exacerbation.

We report the first infant case with hepatosplenic gammadelta T-cell lymphoma after recurrent acute disseminated encephalomyelitis-like, which were rapidly resolved with steroid pulse therapy. The patient had a history of recurrent bronchitis, intractable diarrhea, and failure to thrive since 4 months of age. Immunologic analysis revealed higher percentage of circulating gammadelta T-cells with markedly reduced numbers of CD3TCRalphabetaCD8 T-cells.
