Crystalglobulinemia manifested as acute renal failure and thrombotic vasculopathy

We report a patient with ischemic lesions of thrombotic origin in lower limbs. Subsequently, renal involvement occurs, in view of this involvement, it is suspected that the patient may have an associated vasculitis. After performing the biopsy and with the subsequent diagnosis of monoclonal gammopathy of uncertain significance, the diagnosis is made. We review the most recent bibliography of patients who have been diagnosed with crystalglobulinemia associated with plasma dyscrasia focusing in those with thrombotic vasculopathy or acute renal failure. In our case, in addition to being associated with monoclonal gammopathy of undetermined significance that is less frequent, the debut of the symptoms is years before the detection of the monoclonal peak. This could speak of patients with a low peak of monoclonal component (not detected by immunoelectrophoresis) who could have kidney and vascular damage.
