Oral Squamous Cell Carcinoma of the Right Buccal Mucosa: A Case Report

Abstract

Oral squamous cell carcinoma (OSCC) is indeed one of the most common types of oral cancer, typically affecting individuals over the age of 50. It primarily originates from the squamous epithelial cells lining the oral cavity. While it is relatively rare in individuals under 40 years old, it can still occur, albeit less frequently in that age group. Risk factors for developing OSCC include tobacco use (smoking or chewing), excessive alcohol consumption, chronic irritation (such as from poorly fitting dentures), human papillomavirus (HPV), infection, and certain dietary foods. Early detection and treatment are crucial for improving outcomes and reducing the mortality associated with this type of cancer. This report describes a case of OSCC, staged T2 N0 M0, involving the right buccal mucosa of a 51-year-old male patient. The patient reported intense pain in an ulcer on the right side of his cheek. This report focuses on the etiological factors and a brief literature review of squamous cell carcinoma.

Figure 1. a) Diffused grayish-white area seen with small nodular excrescences having small central red spots all over the palate suggestive of smoker's palate; b) Greyish white patch with interspersed erythematous area seen in the left buccal mucosa; c) A single grayish-white diffused patch is seen with a single irregular erythematous large ulcer in the center. The edges appear to be raised, and the floor contains yellowish-white slough; d) Areas of dark blue indicate the uptake of toluidine staining in nuclei containing RNA and DNA.
