Liposarcoma cells in pleural fluid from two patients with metastatic pleomorphic liposarcoma are described. The major diagnostic feature of such specimens, perceivable by light microscopy, is the presence of solitary, pleomorphic giant cells with cytoplasmic vacuoles. In some cells, transmission electron microscopy revealed numerous cytoplasmic lipidic droplets. With scanning electron microscopy, the cellular surfaces were markedly pleomorphic, with ruffles, blebs and long, thin processes.
