Cryoprobe plus forceps biopsy help early diagnosis and treatment in a case of endobronchial sarcomatoid carcinoma

Sarcomatoid carcinomas (SARCs) of lung are a group of rare but aggressive tumors. They usually present as large peripheral masses on chest roentgenograms, and less present as endobronchial tumors. Although surgical exploration can be proceeded in endobronchial tumors without a definite diagnosis, some special occasions preclude this option. Until now, preoperative diagnosis of SARC when it is endobronchial has been scarcely reported. Herein, we describe a case of endobronchial SARC diagnosed by cryoprobe plus forceps biopsy preoperatively, followed by a timely surgical treatment and a good result.
