Is Rituximab Therapy Associated with Achilles Tendinopathy?

Abstract

Rituximab is a chimeric anti-CD20 monoclonal antibody that is used to treat CD20+ non-Hodgkin's lymphoma, and a wide variety of autoimmune diseases. Rituximab-associated tendinopathy has been described in a few cases in the literature. Here, we present a case of Achilles partial tendon rupture with classic clinical and radiographic findings in a patient treated with rituximab.
