ABSTRACT

OBJECTIVE@#To study the clinicopathological characteristics, diagnosis and differential diagnosis of hypopharyngeal carcinosarcoma.@*METHOD@#Clinical data of one case with hypopharyngeal carcinosarcoma proved by pathology were analyzed retrospectively. The related literatures were reviewed.@*RESULT@#The masses were surgically removed,and the postoperative diagnosis was confirmed to be carcinosarcoma by histopathological examination. After radiotherapy and chemotherapy, the patient recovered well postoperatively without recurrence during 18-month follow-up.@*CONCLUSION@#Carcinosarcoma of the hypopharynx is an extremely rare malignant tumor with distinctive histological, clinical and immunohistochemical features. The final diagnosis depends on histopathology. This tumor should be differentiated from other tumors such as sarcomatoid carcinoma and the reaction of radiotherapy of carcinoma. Surgery is the proper treatment strategy for carcinosarcoma of the hypopharynx. The patients with locally advanced, postoperative residual tumor or tumor without clear safe surgical margin should undergo radiotherapy, and the postoperative follow up should be in time.
