Abstract :
Desmoplastic small round cell tumor is a rare malignant tumor that occurs primarily in young males. Here, a case of small round cell tumor in an adult male successfully treated with a curative concurrent chemoradiotherapy is presented. A 58-year-old man had an intrapelvic tumor. Surgical resection was attempted, but the tumor was unresectable. Needle biopsy was performed and the diagnosis was suggested to be desmoplastic small round cell tumor. Concurrent chemoradiotherapy was performed, and a complete response was obtained. This patient has been alive for 8 years after treatment with no evidence of disease. Concurrent chemoradiotherapy appears to be a useful treatment choice for unresectable desmoplastic small round cell tumor.
