Brown tumors are rare focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone (PTH) on bone tissue in some patients with hyperparathyroidism. Browns tumor is a syndrome associated with an increase in PTH levels by parathyroid glands resulting in hypercalcemia. In the present case report, a 44-year-old female patient presented with a rare case of brown tumor with multiple lesions in the head-and-neck region.

Odontogenic carcinosarcoma (OCS) is a rare malignant odontogenic tumor (OT) with only a few cases reported in the literature. Its synonyms are ameloblastic carcinosarcoma, malignant mixed OT. It is characterized by a true mixed tumor showing malignant cytology of both epithelial and mesenchymal components.

The term cholesteatoma refers to "chole": cholesterol, "steat": fat and "oma,": "tumor". This tumor has been reported to be the most common in the middle ear. The occurrence of such a tumor in the maxillary sinus is deemed to be very rare and hardly 4 cases were reported in India and 26 cases described worldwide.

Background: The Immunomorphological patterns of Lymph Nodes indirectly assess the host immune response facing a malignant tumor. These patterns also help us predict the susceptibility of the patient to Lymph Node Metastasis.
Aims And Objectives: To evaluate the Immunomorphological patterns of Lymph Nodes in Oral Squamous Cell Carcinoma and to correlate them with the histopathological subtype of Oral Squamous Cell Carcinoma, TNM staging and the degree of tumor involvement within the Lymph Nodes.
Introduction: Heat shock proteins are biomarkers regulating the degree of differention and aggressiveness in oral carcinogenesis. The study was carried out to evaluate the expression of HSP 70 in histological grades of epithelial dysplasia and oral squamous cell carcinoma using immunohistochemistry.
Methodology: A sample of 40, which included 10 (Normal), 15 (epithelial dysplasia) and 15 (oral squamous cell carcinoma) were selected.

Introduction: Oral cancer ranks third among all cancers in the Indian population with approximately 45% of call cancer cases in India being diagnosed as oral cancer, among which 20%-50% of the cases are observed to be associated with human papillomavirus (HPV) infection.
Aim: This study aims to detect and evaluate the presence of p16 in oropharyngeal squamous cell carcinoma (OPSCC) patients using immunohistochemistry (IHC).
Materials And Methods: This study was based on samples collected from 21 patients with primary OPSCC who were diagnosed and treated during the period of December 2017-March 2018.
Background: Oral cancer is the 12 most common cancer in women and the 6 in men. Of all oral malignancies, more than 92-95% is Oral Squamous Cell Carcinoma (OSCC). The high risk was due to Lifestyle-related habits such as smoking, alcohol consumption, chewing of areca nut related products which are considered as the major risk factors in OSCC.

The aim of presenting this case of NHL is to highlight the suspicion of its occurrence in the region of unhealed extraction sockets and the significance of its awareness. NHL can be presented in various forms; therefore, a thorough knowledge regarding this malignancy is essential for arriving at the earliest possible diagnosis and therapy for the patient.

These cysts all though do not show similar behavior, they all have the potentiality to recur. Silver nitrate staining of the nucleolar organizer regions (AgNORs) of the benign and malignant lesions is becoming very useful as a diagnostic indicator.

As per previous studies, most patients who develop oral cancer are elderly males who are heavy users of tobacco and alcohol; however, the incidence is increasing in younger individuals and in those who neither smoke nor drink. Many of the genes that code for the detoxification enzymes are polymorphic with abnormal activity profiles.

Most commonly deleterious oral habits such as tobacco smoking and viral etiologies mainly human papillomavirus (HPV) play an important role. p53 polymorphisms mostly homozygous Arginine (Arg) allele has a greater risk of degradation by HPV.

Ameloblastic carcinoma is a rare odontogenic tumour, which is aggressive in nature with extensive local bone destruction that has retained the features of ameloblastic differentiation and also exhibits cytological features of malignancy. It occurs primarily in the mandible in a wide range of age groups.

They are distinct tumors arising in unicentric or multicentric locations from both skeletal and extraskeletal tissues. The most affected region is the facial skeleton, especially the jaws.

Mandibular MPNST may either arise from a preexisting neurofibroma or develop de novo. Because of the greater variability from case to case in overall appearance both clinically and histologically, a case of MPNST of the mandible in a 25-year-old female patient is reported.

It has a propensity for locally aggressive behavior and local recurrence. An occurrence of intra-osseous lesion other than that of odontogenic origin is rare in the jaws.

Background: Saliva, "Mirror of body's health" has long been of particular interest as a substitute for blood for disease diagnosis and monitoring. The radiation effects on salivary glands are of particular interest in which salivary amylase is a good indicator of salivary glands function. Thus, estimation of these parameters represents a reasonable approach in evaluation of patient's risk for disease occurrence, intensity and prognosis.

This suggests that HPV plays a role in the early stages of carcinogenesis but is not a requisite for the maintenance and progression of malignant state. p53 is a tumor suppressor gene that checks the cell and promotes apoptosis and cell repair that can be deactivated by mutations and a viral interaction leading to cancer and individuals with particular polymorphic variant of p53 is more susceptible to HPV-induced carcinogenesis.
