Tumoral calcinosis secondary to chronic kidney disease

Abstract

Objective: to assess the available literature to date regarding tumoral calcinosis in chronic renal disease, focusing on diagnostic tools and therapeutic management available. Methods: using the descriptors "Calcinosis", "Kidney Failure, Chronic", "Therapeutics", "Diagnosis", "Epidemiology", we sought articles in the pubmed database. We included clinical trial articles, meta-analyzes, systematic reviews and clinical cases that were in English, French, Portuguese and Spanish, all in adults. We excluded articles published before 1990 except those that were vital to the definition of tumoral calcinosis. Articles that included "Calciphylaxis" and that did not contribute to the objective of the review, were excluded. Results: a total of 91 articles were included; most were case reports. We found that the most common site of tumor calcinosis was in the upper limbs, followed by skin and hip. One of the key diagnostic recommendations was radiographic images and blood chemistry, and the recommendation regarding treatment is the use of phosphorus binders combined with diet low in calcium and phosphorus. Conclusion: we included a lot of information. Further studies on this condition are needed in Latin America, as well as better grades and quality of evidence to make any recommendation or management guide.
