Evaluation of Safe Margins Using Immunohistochemistry in Oral Squamous Cell Carcinoma.

Background: Hematoxylin & Eosin (H & E) stains have been conventionally used to establish the status of safe margins following resection of primary Oral Squamous Cell Carcinoma. Due to non-specificity of this stain, there is a possibility of false negative results. In this study, we have assessed the role of Immunohistochemistry (IHC) in establishing the status of safe margins.

Lugol's iodine identifies dysplastic tissue in precancerous lesions: A clinical trial.

Introduction: Intraepithelial dysplasia, or "invisible" precancerous lesions, provides a challenge for visualization to the surgical team. The prognostic relevance of dysplasia and carcinoma at surgical margins is well documented.

Materials And Methods: We evaluated the use of Lugol's iodine in visualizing the surgical margins of dysplastic tissue by an observational study of 100 patients having oral precancerous lesions between June 2013 and March 2016.

Parotid angiofibroma.

Angiofibromas are rare, benign, locally invasive vascular tumors, which represent 0.05-0.5% of all head and neck tumors.
