TL;DR: D diagnosis of sarcomatoid squamous carcinoma is challenging because of overlapping histopathological features with other spindle cell tumors, and understanding their clinicopathologic characteristics facilitates their diagnosis and appropriate clinical management.

TL;DR: The significance of positive margins emphasizes the need for adequate surgical resection in patients with oral verrucous carcinoma treated surgically and the presence of either leukoplakia or SMF and tumor location in the upper alveolar-palatal complex is associated with worse outcomes.

TL;DR: NACT led to successful resection and improved overall survival in a significant proportion of technically unresectable oral-cancer patients.

TL;DR: Tobacco, alcohol, areca nut, and human papillomavirus are the common etiologic factors and each follows a unique model of carcinogenesis that leads to a certain distinct presentation and behavior.

TL;DR: Possible role of vimentin in early events of tobacco/areca nut-associated oral tumorigenesis is suggested, which may prove useful to predict the malignant potential of high-risk oral lesions.
