In a 62-year-old female, non-smoker, what kind of lesion is most likely to progress to SCC?

A white patch on the lateral border of the tongue
A smooth red patch of the mid posterior dorsal tongue
A hard lump on the floor of the mouth
Ulceration on the lips

The correct answer is: A smooth red patch of the mid posterior dorsal tongue

In a 62-year-old female non-smoker, a smooth red patch on the mid posterior dorsal tongue is most likely to progress to SCC (squamous cell carcinoma) over other lesions such as a white patch on the lateral border of the tongue, a hard lump on the floor of the mouth, or an ulceration on the lips. This is because red patches on the tongue are commonly associated with oral leukoplakia, a precancerous lesion that may develop into SCC. While other lesions may also potentially progress to SCC, they are less likely in this specific demographic and without a history of smoking. It is important for patients to closely monitor any changes in their oral mucosa and consult with a medical professional for proper diagnosis and treatment.
