An Atypical Case of Relapsing Polychondritis Associated With Waldenström Macroglobulinemia

Relapsing polychondritis is a rare disease characterized by relapsing-remitting inflammation of cartilage and has been found to be associated as a paraneoplastic syndrome to hematologic malignancies. Here, we present an atypical case of relapsing polychondritis associated with lymphoplasmacytic lymphoma or Waldenström macroglobulinemia, responsive to rituximab but complicated by simultaneous relapse of both conditions when observed off therapy.
