Hyperphosphatemic Multifocal Tumour Calcinosis in a 14 year old boy

Abstract

Background: Tumour Calcinosis is a condition wherein amorphous calcium phosphate crystals get deposited in the soft tissues around the joints. Hyperphosphatemic type of Tumour Calcinosis is predominantly seen in Afro-American / Afro-Caribbean descent. It creates a diagnostic dilemma because of its rare and sporadic incidences. Case report: We report the case of hyperphosphatemic multifocal Tumor Calcinosis in a teenage boy, which was entirely unilateral affection, who underwent several futile surgeries before the actual diagnosis was made. Conclusion: Tumour Calcinosis is a rare differential diagnosis for soft tissue calcification in the periarticular region. Though the Hyperphosphatemic type has a familial tendency, diagnosing the index case without positive family history can be challenging. This leads to delay in the diagnosis of the condition and mismanagement. We report a case of hyperphosphatemic multifocal Tumour Calcinosis in a fourteen year old boy and briefly discuss the epidemiology, etiology, clinical, and radiological features of this condition.
