A novel histological grading system for minor salivary gland involvement in oral submucous fibrosis patients with clinico-pathological validation.

Background: The involvement of minor salivary glands (MSGs) with fibrosis in oral submucous fibrosis (OSMF) pathology is a quite conceivable fact. However, very little attention has been given to the status of MSGs in OSMF.

Methodology: Total 53 cases of OSMF were recruited and demographic details, mouth opening, clinical oral dryness score (CODS), and buccal mucosal MSG flow rate were determined.

Elevated tissue nitric oxide in oral squamous cell carcinoma.

Context: Nitric oxide (NO) is a diatomic molecule that has been implicated in tumor progression of oral squamous cell carcinoma (OSCC). However, the mechanism of NO affecting tumor growth and progression remains unknown. Tumor progression has been recently received considerable attention, and there is increasing evidence of correlation of tumor biology and behavior.

Solitary Non Syndromic Oral Plexiform Neurofibroma: a Case Report and Review of Literature.

In oral cavity neurogenic tumors are rare, especially if they are malignant. Neurofibromas are the benign tumors of nerve sheath origin involving multiple nerve fascicles of the smaller branches of peripheral nerves. They may present as solitary lesions or as a part of generalized syndrome of neurofibromatosis also known as von Recklinghausen's disease (VRD) or very rarely as multiple neurofibromas without VRD.

Myoepithelial cell carcinoma of the oral cavity: A case report and review of literature.

Myoepithelial carcinoma (MC) is a malignant salivary gland neoplasm whose tumor cells demonstrate cytologic differentiation toward myoepithelial cells and lack ductal or acinar differentiation. It is a relatively rare tumor and many a times remains undiagnosed because of histopathological heterogeneity. It represents about 0.

Orthokeratinizing odontogenic cyst of maxilla with complex odontoma.

The orthokeratinized odontogenic cyst (OOC) and odontoma are the odontogenic cyst and tumor respectively that are minimally invasive neoplasms of head and neck region. OOC is a rare variant of odontogenic cyst characterized by the presence of excessive orthokeratin covering the cystic lining. Odontoma is a benign neoplasm/hamartoma often discovered accidently on panoramic radiographs.
