dc.description.abstractIn sarcomatoid renal cell carcinoma (RCC), it is generally accepted that the sarcomatoid portion is derived from metaplastic transformation of carcinoma. Sarcomatoid RCCs account for about 1-8% of all renal tumors. Macroscopically, tumors generally form encapsulated masses and show invasive growth. Sarcomatoid RCCs originate from all subtypes of RCCs, including conventional, papillary, chromophobe, and collecting duct carcinomas. With regard to the growth pattern of the sarcomatoid component, malignant fibrous histiocytomatous, fibrosarcomatous and unclassified sarcomatous patterns are frequently seen. Immunohistochemically, sarcomatoid RCCs are generally positive for AE1/AE3, epithelial membrane antigen (EMA) and vimentin and negative for desmin, actin and S-100. Little is know about genetic alterations in sarcomatoid RCCs. Further studies are therefore needed to identify the key gene involved in sarcomatoid transformation of
