La calcinose tumorale : à propos d’un cas

Two new cases of pediatric tumoral calcinosis

“…TC is a benign condition characterized by a deposit of calcium material in the extra-articular soft tissues [ 1 , 2 ]. It is rare with ~300 cases reported, in which ~100 are familial and ~30 are pediatrics [ 1 , 3 , 4 , 5 ].…”

“…TC is a benign condition characterized by a deposit of calcium material in the extra-articular soft tissues [ 1 , 2 ]. It is rare with ~300 cases reported, in which ~100 are familial and ~30 are pediatrics [ 1 , 3 , 4 , 5 ]. TC are asymptomatic and especially painless unless they reach certain size to cause nerve or vascular compression or if they are in a particular location such as spinal [ 3 , 5 ].…”

“…[ 2 ], the physiopathology of TC remains controversial, even if the team of Slavin [ 6 ] has raised the possibility of a process of repairing a metabolic phospho-calcic disorder, which could be exaggerated by episodes of bleeding, and therefore raises the possibility of repeated trauma [ 3 , 7 ]. Thus, TC is frequently localized in the extra-articular soft tissues of the hip, posterior region of the elbow or shoulder, foot and knee [ 1 , 2 , 3 , 5 , 8 , 9 ]. Other localizations are rare including ankle or leg like one of our cases mentioned above.…”

“…Imaging is essential to diagnose TC. Ultrasound shows a calcified mass with posterior shadowing and containing echogenic components with liquid–liquid level, without Doppler flow [ 1 , 10 ]. On X-ray, TC corresponds to a multi-lobed mass of extra-articular projection without damage of bone structures and articular surfaces.…”

“…Tumoral calcinosis (TC) is characterized by a deposit of calcium phosphate crystals in the extra-articular soft tissues, which are rare benign conditions, especially in children [ 1 ]. Apart from esthetic problems, these lesions are disabling by the importance of the tumor volume and the associated algic symptoms, thus requiring surgical resection.…”
