Summary
A case of a highly malignant extraskeletal osteosarcoma is reported. Although biopsy is not considered necessary in cases of heterotopic calcification when the aetiology is known, malignancy should be suspected when the cause is questionable.
Résumé
Ostéosarcome extrasquelettique au développement fortement malin. En résumé, un diagnostic par biopsie et examen histologique n'est pas nécessaire dans la plupart des cas d'ossifications ou de calcifications hétérotopiques, l'étiologie du développement étant claire. Comme nous l'avons démontré, ce sont les cas de calcifications non-classifiées qui sont suspects. Une biopsie doit alors être entreprise dans les plus brefs délais.
