Accuracy of palpation, ultrasonography, and computed tomography in the evaluation of metastatic cervical lymph nodes in head and neck cancer.

Introduction: India accounts for the majority of oral cancer cases occurring worldwide. The metastasis of oral cancer to the regional lymph nodes and distant sites determines the prognosis and the survival rate of this disease.

Objectives: The aim and objectives of this study were to evaluate the accuracy of preoperative clinical methods such as palpation, ultrasonography (USG), and computed tomography (CT) in comparison with postoperative histopathological findings in determination of metastatic cervical lymph nodes and also to assess whether combining these techniques increases the specificity and sensitivity of lymph node metastasis in oral squamous cell carcinoma (SCC).

Peripheral calcifying epithelial odontogenic tumor - Case report.

The calcifying epithelial odontogenic tumor (CEOT), Pindborg tumor is a benign, slow growing, but locally invasive neoplasm. It is known to have a common intraosseous variant and a very rare extraosseous variant. We report an unusual case of an extraosseous variant of CEOT of unusual large size and maxillary anterior location, the treatment was planned considering the clinical, radiological and histological features.

Epidermal inclusion cyst of the mandible after extraction of a third molar: case report.

Epidermal inclusion cysts of the head and neck are rare. We report the case of a non-traumatic epidermal inclusion cyst in the submandibular region, with both intraosseous and extraosseous components, which communicated with the socket of a third molar extracted 12 years previously.

Histological significance of p53 gene expression in squamous cell carcinoma of the buccal mucosa.

Introduction: Oral Squamous Cell Carcinoma (SCC) results from genetic mutations which activate the oncogenes and inactivate the tumor suppressor gene namely TP53. Despite the use of multimodality treatments the prognosis of oral SCC has not changed significantly.

Purpose: To evaluate 1) if there is any correlation between the two prognostic indicators i.
