VLOK, Susanna C.S.; WAGENER, Georg W.W.  e  ZAHARIE, Dan. Secondary chondrosarcoma: Malignant transformation of pre-existing hereditary and non-hereditary cartilaginous lesions. S. Afr. J. radiol. (Online) [online]. 2014, vol.18, n.2, pp.1-5. ISSN 2078-6778.  http://dx.doi.org/10.4102/sajr.v18i2.703.

Secondary chondrosarcoma is a malignant hyaline cartilage tumour originating from a cartilaginous precursor, either osteochondroma or enchondroma. We contrast two different cases of biopsy-proven secondary chondrosarcomas resulting from benign, pre-existing cartilaginous lesions - our aim is to contrast and compare these two benign conditions consisting of multiple cartilaginous lesions - one hereditary and the other non-hereditary - and emphasise their potential for malignant transformation.
