Sarcomatoid carcinoma is a biphasic neoplasm composed of highly complex, intimately admixed malignant epithelial and mesenchymal elements. We herein report a rare case of cutaneous metastasis of pulmonary sarcomatoid carcinoma that contains liposarcomatous, rhabdosarcomatous and chondrosarcomatous heterologous differentiation, and review relevant literatures to lead to a better understanding of this rare but highly aggressive tumor.
