Treatment
The patient underwent an incisional biopsy with intra-operative findings demonstrating tumor burden extending through the chamber wall to the external surface of heart, including invasion into septum. Frozen section demonstrated a low-grade neoplasm suspicious for myxoid liposarcoma. Cytopathology later confirmed a low-grade myxoid neoplasm which was consistent with metastatic liposarcoma (Figure 4).
