A 15-year-old child, without particular medical history, presented with painless masses of the hips, gradually increasing in volume. A Computed Tomography (CT) of hips objectified bilateral peri-articular calcified formations made of the clustered juxtaposition of nodular or oval lesions, well limited, containing for some of them horizontal levels related to calcium sediments (figures). The diagnosis of tumoral calcinosis was strongly evoked. The patient underwent surgical excision. The anatomopathological examination subsequently confirmed the diagnosis.
