Aim: The purpose of the study was to evaluate the expression of stathmin in different histological grades and tumor, node, metastasis (TNM) staging of Oral carcinoma and various grades of oral dysplasia. The study also aims at observing the stathmin expression with respect to lymph node metastasis.

Materials And Methods: A total of 90 histopathologically confirmed tissue sections were acquired, of which 30 sections of oral dysplasia, 30 oral squamous cell carcinoma (OSCC) and 30 normal tissue sections were stained immunohistochemically with stathmin.

Background And Objectives: Stathmin is a phosphoprotein, which in its phosphorylated/unphosphorylated states plays a major role in polymerization/depolymerization of microtubules, respectively. Assembly of microtubules is an important aspect of cell division called mitosis. Hinderance in the function of stathmin could lead to damage in the mitotic process resulting in aneuploidy which is common manifestation of malignancies.

Background: Stathmin is an intracellular phosphoprotein that controls the microtubule dynamics by further regulating proper attachment and alignment of chromosomes in a dividing cell. Thus, any mutation or aberrantly expressed protein that reduces the fidelity of spindle assembly will enhance chromosomal instability contributing to aneuploidy. Oral Squamous Cell Carcinoma is an extensively studied malignancy that occurs due to accumulated genetic changes due to carcinogens.

Introduction: Histological stains are dyes that bind to a variety of tissues. Modified Gallego's (MG) stain is a modification of Lille's stain that can be used as a differential stain for identification of hard tissues in oral pathological lesions.

Objectives: The objective of this study was to identify the presence of hard tissues such as enamel, dentin and cementum in normal extracted teeth and odontogenic tumors using MG stain and to compare the efficacy of MG stain with hematoxylin and eosin (H&E) stain.

Polymorphous adenocarcinoma (PAC) is a distinctive salivary gland neoplasm that predominantly occurs in the minor salivary glands. The tumor is characterized by cytological uniformity, morphological diversity, an infiltrative growth pattern and low metastatic potential. It presents as an asymptomatic, slow- growing mass within the oral cavity.
