A rare malignant periurethral carcinosarcoma with aggressive behavior: A case treated with a multimodal treatment approach

초록

Carcinosarcoma is an aggressive tumor that can develop in any organ but is rarely observed in the urinary tract. Given the radioresistant nature of carcinosarcoma and the rapidly regrowing tumor after primary surgery, carcinosarcomas that developed in the body showed poor outcomes regardless of aggressive management. However, the specific optimal treatment for periurethral carcinosarcoma remains unknown. The present study reports a rare case of periurethral carcinosarcoma with metastasis of the skull after receiving surgery for primary tumors with adjuvant concurrent chemoradiation therapy. © 2021 The Authors
