GALINDO GOMEZ, Abelardo et al. Hyperphosphatemic tumoral calcinosis in pediatrics: Case report. Bol. Med. Hosp. Infant. Mex. [online]. 2014, vol.71, n.3, pp.167-173. ISSN 1665-1146.

Background: Tumoral calcinosis is a rare disease whose prevalence is hard to determine due to the scarcity of the reported cases. This disease is distinguished by single or multiple periarticular deposits of calcium and phosphate due to a failure in the phosphate recapture inhibition at the proximal renal tubules, resulting in hyperphosphatemia. There is no optimal treatment described because there are a reduced number of cases, which makes it difficult to assess the results. Case report: We present the case of a 10-year-old female with a growing mass in both elbows and index finger of the right hand. Diagnosis was made of hyperphosphatemic tumoral calcinosis. Surgical and medical treatment were given, with no relapse during a 6-month follow-up. Conclusions: Tumoral calcinosis is a rare entity that should be considered when a patient has a single or multiple periarticular calcifications. Medical treatment is oriented to restoring the calcium-phosphate balance. Surgical treatment should be offered for aesthetic and functional reasons.
