It was the first monoclonal antibody that was approved for the treatment of non-Hodgkin lymphoma, rheumatoid arthritis, and other cutaneous lymphoid malignancies. There are many off-label uses of rituximab, such as systemic lupus erythematosus, autoimmune hemolytic anemia, multiple sclerosis, graft-versus-host disease, chronic lymphocytic leukemia, and chronic immune-mediated thrombocytopenia. Among the rare side effects associated with rituximab treatment is vasculitis, more specifically, leukocytoclastic vasculitis. Here, we describe a 21-year-old Saudi female with leukocytoclastic vasculitis occurring three months after treatment with rituximab.展开更多
