[Synchronous primary double: condrosarcoma and sarcoma high grade fusocelular associated with Maffucci syndrome]

Maffucci syndrome is characterized by the presence of multiple enchondromes and hemangiomas that can affect soft tissues and other organs. The risk of malignant transformation of lesions is 100% during the life of the individual, with chondrosarcoma being the most frequently associated malignant tumor. We present the case of a 44-year-old man diagnosed with Maffucci syndrome who developed a synchronous double primary: chondrosarcoma and high-grade multicenter fusocellular sarcoma of scapular and tricipital region, was treated with disarticulation interscapule-thoracic, presented accelerated progression and lung disease. There are other neoplasms associated with Maffucci syndrome, such as pancreatic adenocarcinoma, mesenchymal ovarian tumors, gliomas, astrocytomas and pituitary tumors. It is therefore very interesting to report the uncommon association between fusocellular sarcoma and secondary chondrosarcoma in patients with Maffucci syndrome. Follow-up in this group of patients is complex and is based on the intentional search for accelerated growing lesions, paying attention to progressive growth injuries, clinical symptoms or radiological malignancy data.
