Background:Calciphylaxis is a well-known entity in end-stage kidney disease and after renal transplant. Cases of nonuremic calciphylaxis (NUC) have also been reported, but data on this rare condition are mainly empirical.Objective:We discuss a case of NUC secondary to spontaneous tumour lysis syndrome in a patient who had chemotherapy for non-Hodgkin lymphoma and present a review of the literature to better characterize malignancy-associated NUC.Methods:We identified 12 published cases of malignancy-associated NUC.Results:This systematic review of malignancy-associated NUC did not show a relationship between the type of malignancy, the distribution of skin lesions, or mortality. However, distal more than proximal involvement seems to be more frequently associated with calcium phosphate imbalance.Conclusion:Clinicians must maintain a high index of suspicion for calciphylaxis when evaluating patients with cutaneous lesions developed in the setting of malignancy.
