Some authors also use the term synonymously with pleomorphic carcinomas of the lung, while the WHO 1999 classification system places the latter as a separate entity.
Tumors usually shows a concurrent presence of malignant epithelial and homologous sarcomatoid spindle cell components by co-expressing cytokeratin and vimentin in various degrees.
