Erythroplakia is best described as which of the following?

• A. White plaque that cannot be rubbed off
• B. Red patch in the oral mucosa
• C. Non-infectious itchy rash
• D. A salivary gland disorder

Answer: (B)

The main idea is recognizing how erythroplakia presents in the mouth. It shows up as a red patch on the oral mucosa, often described as a velvety, flat area. The red color comes from thinning of the surface epithelium with more visible underlying blood vessels, which sets it apart from white-appearing lesions. This is important because erythroplakia carries a higher risk of dysplasia or malignant change than white patches, so it typically requires prompt biopsy and close monitoring. It’s not a white plaque (that would point to leukoplakia), nor is it a non-infectious itchy rash or a salivary gland disorder.
