Rare myxoid liposarcoma metastasis to the interventricular septum of the heart

We present a case of a 36-year-old man with a history of recurrent myxoid liposarcoma. Primary location was in the left popliteal area. After extirpation of the tumor, metastatic tumor was subsequently revealed in the right axilla. Each surgical extirpation was followed by radiation therapy and brachytherapy. Cardiac metastasis was accidentally diagnosed with PET/CT during the staging process. The patient was asymptomatic and was admitted to our institution for further diagnostics and treatment. After confirmation of its location, the tumor was excised. Histological examination revealed myxoid liposarcoma.
