Treatment of pharyngeal non-Hodgkin lymphoma in a patient with Wiskott-Aldrich syndrome.

Wiskott-Aldrich syndrome (WAS) is characterized by primary immunodeficiency, thrombocytopenia and eczema. Patients with WAS have an increased risk to develop tumors. Non-Hodgkin lymphoma (NHL) represents the most common malignancy occurring in WAS-affected patients, diffuse-large-B-cell lymphoma is the most frequently encountered variant. We describe a case of a patient with WAS and NHL in the pharynx, an atypical tumor site presentation. The patient was successfully treated with a reduced dose chemotherapy regimen plus anti-CD20 monoclonal antibody. He is in complete remission 3 years from the start of treatment.
