Sarcomatoid carcinoma: A rare biphasic variant of OSCC: A case report

Abstract

Sarcomatoid carcinoma is a type of spindle cell neoplasm. These varieties of neoplasms comprise of a diverse collection of benign and malignant neoplasms. Sarcomatoid carcinoma, also known by various other names such as Spindle cell carcinoma, Lane's tumor, to name a few, is an exceedingly rare and aggressive variant of squamous cell carcinoma [3,7,8] The variation in its nomenclature reflects the divergent interpretation of the sarcomatoid component as reactive or neoplastic, mesenchymal or epithelial [8] . It accounts for <1% of total tumors occurring in the jaw. Role of imaging in diagnosis of such lesions is irreplaceable considering the location and nature of the lesion. In the present case of a 44 year old female patient with inability to open the mouth since over 6 months; the diagnosis was especially challenging due to location of the lesion and clinical symptoms. We aim to highlight significance of thorough clinical examination and appropriate imaging modalities for an unusual presentation of a rare neoplasm which can leave clinicians baffled.
