Brown tumor of hyperparathyroidism with multiple lesions.

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 - A rare case report with review of literature.

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.

Evaluation of immunomorphological patterns of cervical lymph nodes in oral squamous cell carcinoma.

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.

Expression of Heat Shock Protein 70 in Oral Epithelial Dysplasia and Oral Squamous Cell Carcinoma: An Immunohistochemical Study.

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.

Evaluation of genotoxicity by micronucleus assay in oral leukoplakia and oral squamous cell carcinoma with deleterious habits.

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.

Lymphoma in an extraction socket.

Non-Hodgkin's lymphoma (NHL) is a lymphoproliferative malignancy that can involve both lymph node and lymphoid organs as well as extranodal organs and tissues. 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.

The "TROJAN HORSE" of a Dental Visit - Synovial Sarcoma.

The term "synovial sarcoma (SS)" is a histological error, a misnomer as it neither arises from nor differentiates toward synovium. Head and neck region is the most commonly affected region after extremities, representing 5% of all cases. This case report focuses to discuss a case of a SS that was diagnosed after an inadvertent root canal therapy.

Evaluation of Genetic Polymorphisms in Glutathione S-Transferase Theta1, Glutathione S-Transferase Mu1, and Glutathione S-Transferase Mu3 in Oral Leukoplakia and Oral Squamous Cell Carcinoma with Deleterious Habits using Polymerase Chain Reaction.

Context: Oral squamous cell carcinoma (OSCC) is the sixth most common cancer in the world. 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.

Malignant Peripheral Nerve Sheath Tumor -A Rare Malignancy in Mandible.

Malignant Peripheral Nerve Sheath Tumor (MPNST) is biologically an aggressive tumor that is usually found in the extremities, trunk and infrequently found in the head and neck area particularly in the jaws, arising from the cells allied with nerve sheath. 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.

Desmoplastic ameloblastoma.

Desmoplastic ameloblastoma is a relatively rare variety of ameloblastoma and only very few cases have been reported so far. The present case is an elderly man who had reported with a swelling in the anterior mandible which turned up to be desmoplastic ameloblastoma. Proper diagnosis is necessary to report such a case, so that the actual incidence can be noted.

Photodynamic therapy: the imminent milieu for treating oral lesions.

Photodynamic therapy (PDT) is used in curative and palliative treatment of head and neck squamous cell carcinoma (HNSCC) and other oral lesions. Oral infections (such as mucosal and endodontic infections, periodontal diseases, caries, and peri-implantitis) are among the specific targets where PDT can be applied Photodynamic therapy (PDT) efficacy depends on the local dose deposited in the lesion as well as oxygen availability in the lesion. Further long-term clinical studies are necessary in establishing a more specific place of the technique in the field of dentistry.
