title: Eosinophilia associated with a composite lymphoma.
abstract: We report a case of composite lymphoma heralded by a hyper-eosinophilia syndrome. Combination of immunophenotyping and gene rearrangement analysis allowed us to confirm malignancy and to detect a minor oligoclone B within a malignant T-cell predominant population. No evidence of retroviral infection was found using western blot and gene amplification techniques.
