A rare case of idiopathic tumoral calcinosis: Case report

Idiopathic tumoral calcinosis is a very uncommon benign disease, defined by the presence of calcified deposits in periarticular tissues. The pathogenesis is yet not well understood. The treatment remains essentially surgical and the prognosis is very good. We report a case of tumoral calcinosis in a 50-year-old patient presenting with a firm mass of soft tissues and limitation of motion of his right hip joint. The diagnosis was first hand suggested radiologically due to the presence of voluminous periarticular calcifications with no bone involvement, and later on confirmed in pathology results. Therefore, imaging continues to be the best modality in order to assess the extension, evaluate the prognosis, and select the adequate surgical approach.
