Non-Hodgkin's lymphoma in Job's syndrome: a case report and literature review.

Job's or hyper immunoglobulin E recurrent infection syndrome (Hyper-IgE syndrome) is a rare, often inherited multisystem disorder, characterized by cutaneous abscesses, pneumonia, elevated IgE levels and skeletal defects. We report a case of a 22-year-old man with Job's syndrome who presented with back pain. He was found to have diffuse large B-cell lymphoma involving his second lumbar vertebrae and spleen. Treatment with dose-adjusted EPOCH-rituximab (DA-EPOCH-R) chemotherapy achieved a complete remission after 4 cycles. A review of reported cases of lymphoma in Job's syndrome indicates an increase in relative risk of 259 (95% confidence interval 102, 416). The cause of the increased risk has yet to be defined but has similarities to a pathogenetic model of AIDS related lymphoma. In previous reports of lymphoma in Job's syndrome, patients presented with extranodal disease and had poor outcomes. With appropriate chemotherapy and hematological support, lymphoma associated with Job's syndrome can achieve complete remission.
