Abstract
Large T-cell lymphoma was diagnosed in a 13-year-old girl with hyperimmunoglobulinemia E syndrome (HIES). Her past medical history included severe dermatitis, recurrent pneumonia, urinary tract infections, mucocutaneous herpetic infections, fungal skin infections, and staphylococcal sepsis. The diagnosis of HIES, based on the clinical features and a serum IgE level of >20000 IU/ml, was established when the girl was 6 years old. This is the eighth case of lymphoma in a patient with HIES reported in the English-language medical literature. HIES has not usually been considered a predisposing factor for malignancy, but in view of the rarity of HIES and the young age of the patients, this association seems to be more than coincidental. A link between lymphoma and Epstein-Barr virus (EBV) infection in patients with HIES has been proposed. Serological tests for EBV in our patient were positive 6 years prior to the development of the lymphoma; however, examination for EBV DNA in the lymph node biopsy failed to detect EBV in the tumor.
