title: [Hyper-IgE syndrome--two case reports of unusual complications].
abstract: The hyper-IgE syndrome (HIS) is a complex immunologic disease, caused by an unknown basic defect. We report on two cases showing complications, which have not been described so far. Case 1: A 15-year-old boy suffering from HIS developed a liver tumour with severe eosinophilic infiltration and degranulation. The transformation process of the liver histologically resembled focal nodular hyperplasia. Therapy with cyclosporine A did not lead to clinical benefit. Now, a therapeutic attempt with interferon gamma is made. Case 2: In a 17-year-old female HIS patient, multiple papillomas and ulcers of the mucous membrane, caused by infection with human papilloma virus, emerged in the ENT region. Under treatment with interferon alpha, papillomatosis could be restrained. As therapy of the hyper-IgE syndrome only symptomatic treatment has been recommended so far. Future therapies should strive for systemic immunomodulation by application of cytokines or soluble cytokine receptors like interferons or sIL-4R.
