title: Sarcomatoid carcinoma in the trachea: A case report and literature review.
abstract: Tracheal sarcomatoid carcinoma is an extremely infrequent neoplasm with unclear pathogenesis and clinical outcomes. To date, only two cases have been described in English literature. We report a case of a 37-year-old patient complaining of hemoptysis, dyspnea, and cough. An intraluminal polypoid mass in the trachea was found and ultimately diagnosed as tracheal sarcomatoid carcinoma in the cervical trachea with both carcinomatous and sarcomatoid morphology. The patient is alive without recurrence after segmental resection of the trachea. We also present a comparative analysis of our case with a prior tracheal sarcomatoid carcinoma case.
