title: [Giant tumoral lesion in the left atrium: an uncommon case of undifferentiated cardiac sarcoma].
abstract: Primary cardiac tumors are rare, with an incidence ranging from 0.0001% to 0.030%; 80% are benign, while sarcomas account for 95% of malignant tumors. The authors report the case of a 75-year-old patient with a giant mass in the left atrium. The final diagnosis was of an undifferentiated cardiac sarcoma. This tumor represents a real challenge not only for timely diagnosis, but especially the therapeutic approach to adopt.
