Vasoproliferative retinopathy secondary to Waldenström's disease.

A 66 year-old patient, monitored for diabetic retinopathy refractory to multiple treatment methods despite a good metabolic control, referred to progressive weight loss. For this reason, a systemic study was performed, detecting anaemia, elevation of the erythrocyte sedimentation rate, and hyperproteinaemia due to elevated serum levels of monoclonal IgM. Subsequently, by performing a bone marrow biopsy and genetic study, the diagnosis of Waldenström macroglobulinaemia was made.
