Despite the combined (surgery, chemotherapy, radiotherapy, and immunotherapy) modalities of treatment, the prognosis remains poor, mostly because of recurrence and distant metastasis. Cancer stem cells (CSC) are thought to be responsible for the development and spread of tumors.

Methodology: This cross-sectional study included 48 patients of OSCC who underwent surgical resection. All the histopathological adverse features such as DOI, LVI, PNI, ENE, margin status were noted.

Crystalloids may be seen in a variety of salivary gland lesions, but their presence is not common. Among various types of crystalloids, amylase crystalloids are usually found in benign lesions of the salivary gland. Here, we report a case of a 76-year-old male with swelling on the angle of the mandible left side for 15 days.

Although ultrasonography-guided fine-needle aspiration cytology (USG-FNAC) has emerged as an effective diagnostic the tool for the precise diagnosis of gallbladder lesions, data on its diagnostic utility and cytomorphological categorization of gallbladder lesions are lacking.
Aims: To study the diagnostic utility of USG-FNAC in gallbladder lesions.
