ABSTRACT
Chondrogenic tumors are typically well recognized on radiographs, but differentiation between benign and malignant cartilaginous lesions can be difficult both for the radiologist and for the pathologist. Diagnosis is based on a combination of clinical, radiological and histological findings. While treatment of benign lesions does not require surgery, the only curative treatment for chondrosarcoma is resection. This article (1) emphasizes the update of the WHO classification and its diagnostic and clinical effects; (2) describes the imaging features of the various types of cartilaginous tumors, highlighting findings that can help differentiate benign from malignant lesions; (3) presents differential diagnoses; and (4) provides pathologic correlation. We attempt to offer valuable clues in the approach to this vast entity.

Los mixomas intramusculares son tumores benignos y poco frecuentes, que se presentan predominantemente en los miembros inferiores. Más infrecuente es la asociación de mixomas y de displasia fibrosa, generalmente poliostótica. Esta asociación se conoce como síndrome de Mazabraud, de la que se han descrito aproximadamente 81 casos en la literatura. Presentamos un nuevo caso de esta rara asociación, para enfatizar la importancia de reconocer este síndrome en el diagnóstico y manejo adecuado del paciente (AU)
Intramuscular myxomas are benign and rare tumors that affects predominantly the lower limbs. The association of myxomas and fibrous dysplasia, usually polyostotic, is rarer. This association is known as Mazabraud's syndrome, of which about 81 cases have been described in the literature. We present a new case of this uncommon association to emphasise the importance of recognizing this syndrome in the diagnosis and appropriate management of the patient (AU)
