title: Reversible panhypogammaglobulinemia associated with phenytoin treatment.
abstract: We report the case of a 24-y-old woman who presented with repeated episodes of otitis due to panhypogammaglobulinemia and low levels of mature CD19 + B cells (84 cells/microl) associated with phenytoin treatment. Lymphocyte subpopulations and immunoglobulin levels need to be monitored if symptoms indicating immunodeficiency occur after the initiation of this treatment.
