Sarcomatoid Carcinoma: A Clinicopathological Dichotomy.

Spindle cell carcinoma (SpCC) or sarcomatoid carcinoma is an uncommon biphasic malignant neoplasm occurring mainly in the upper aerodigestive tract. It has spindled or pleomorphic tumor cells simulating a true sarcoma with epithelial origin. WHO recognized this tumor as an aggressive variant of squamous cell carcinoma and further designated it as spindle cell carcinoma. This neoplasm is known for its propensity of recurrence and metastasis reinforcing the importance of its proper diagnosis. In our case report, we talk about sarcomatoid carcinoma involving the oral cavity having a high metastasizing rate according to histopathological and immunohistochemical features.
