放射線照射後に発生した陰茎癌肉腫の1例

A CASE OF CARCINOSARCOMA ARISING IN IRRADIATED PENILE GLANS

　放射線照射後に癌または肉腫が発生することは，よく知られた事実であり，また少なからざる症例も報告されている。われわれは陰茎癌の放射線治療後に，癌の局所再発とともに肉腫を併発した症例を経験し，癌肉腫として学会などにその概要を報告したが^1,2），泌尿器科領域における放射線照射後の悪性腫瘍発生は極めて稀であるので，この観点からの考察を行うことにした。

A 46-year-old man, who had received the radiotherapy on his penile cancer about 8 years ago, suffered again from the tumor of his penile glans, which was thought to consist of recurrent cancer and postirradiation sarcoma. The patient underwent a radical amputation of penis combined with a post-operative chemotherapy, and is still alive wthout the recurrence of his tumor. Although more than 20 cases of penile sarcoma were reported in Japan, no case arising after radiotherapy was found.
