“…Tumoral calcinosis (TC), a distinct clinico-histological entity, is a form of idiopathic calcinosis cutis, which is characterized by tumor-like periarticular deposits of calcium, mainly found in the regions of hip, shoulder, elbow, and other pressure points, rarely affecting distal locations such as the hands and feet. [ 8 ] Mostly, it affects young adults, but it can occur as early as 4 years of age,[ 9 ] the present patient being 13 years old. Although the exact cause is unknown, a pathogenesis-based classification has subdivided this entity into three types: (1) primary normo-phosphatemic tumoral calcinosis (NPTC), (2) primary hyperphosphatemic tumoral calcinosis, and (3) secondary tumoral calcinosis, characterized by the presence of underlying disorders.…”
