Rituximab is a monoclonal antibody against the surface antigen CD20 on B lymphocytes, and it is largely used to treat lymphoproliferative and rheumatological conditions. In a very few published case reports, rituximab has been used as an investigational drug to treat severe insulin allergy refractory to conventional therapy.

Extensive immunologic evaluation suggested the reaction was related to insulin allergy. Skin biopsy revealed sublobular panniculitis.
