Abstract: A case of cutaneous undifferentiated pleomorphic sarcoma(UPS) is reported. A 74-year-old female presented with nodules on the both elbows and the left forearm for more than 10 months. Histopathological examination of lesion from the left elbow showed the pleomorphic tumor cells arranged in a storiform pattern in the dermis. Tumor cells were fibroblasts-like or histiocyte-like with bizarre multinucleated giant cells and increased mitosis. Immunohistochemical staining revealed that the tumor cells were positive for CD68, CD99, CD163, Ki-67(75%) and vimentin. The histopathological changes and immunohistochemical staining supported the diagnosis of cutaneous UPS.
