title: Desmoplastic small round cell tumor of the lung.
abstract: We report a rare case of desmoplastic small round cell tumor, which arose from the left lung. A 25-year-old man was found to have an abnormal shadow during a routine physical examination and was admitted to our hospital. A thoracoscopic tumor biopsy was performed under general anesthesia. According to the histopathologic findings of permanent sections, the tumor was composed of sharply outlined nests, clusters, and trabeculae of small round to oval cells separated by a spindle-shaped desmoplastic stroma. A gene analysis revealed chimera genes of Ewing's sarcoma and Wilms' tumor by reverse transcription polymerase chain reaction.
