Rituximab, a human-mouse, chimeric, monoclonal antibody that targets the B-cell CD20 antigen and causes rapid and specific B-cell depletion, is indicated for the treatment of low-grade or follicular, relapsed or refractory, CD20+ B-cell, non-Hodgkin lymphoma (NHL). We report the case of a middle-aged woman with psoriasis who experienced a partial sustained remission of her psoriasis after treatment with rituximab for NHL and discuss potential pathophysiologic mechanisms for this unexpected effect in a condition known to be mediated by T cells.
