Li-Fraumeni syndrome is a disease with autosominal dominant heredity, characterized by the appearance of multiple tumors in young patients, first described in 1969 by Frederick P. Li and Joseph F Fraumeni. The cause for the disease is generally a mutation in the p53 gene on chromosome 17. We report a 46-year-old female patient. In February 2008 she presented at our clinic with a cardiac tumor. CT imaging showed a tumor obstructing the right ventricular outflow tract (RVOT) and infiltrated the pulmonary artery. Intraoperatively, the tumor reached the bifurcation of the pulmonary artery with infiltration of the pericardium. To remove the tumor, the pulmonary artery had to be resected. The RVOT was reconstructed with a Contegra漏 graft. Due to the medical history we performed a genetic analysis, which confirmed Li-Fraumeni syndrome. Histology showed a low differentiated pleomorphic sarcoma. After 9 months of follow-up the patient has fully recovered with no tumor recurrence of the heart.
