Which of the following is not considered a benign skin lesion?

1. Seborrheic keratosis

2. Lentigo

3. Actinic keratosis

4. Rosacea

The correct answer is: Actinic keratosis

Actinic keratosis is not considered a benign skin lesion; rather, it is classified as a precancerous condition. It arises due to long-term sun exposure, leading to changes in the skin cells. These lesions appear as rough, scaly patches and indicate a risk of progression to squamous cell carcinoma if left untreated. On the other hand, seborrheic keratosis, lentigo, and rosacea are typically regarded as benign. Seborrheic keratosis consists of non-cancerous, wart-like growths that can vary in color and texture. Lentigo, often referred to as liver spots or age spots, are flat brown spots resulting from UV exposure but are benign in nature. Rosacea, characterized by facial redness and visible blood vessels, is a chronic and benign skin condition that does not imply the presence of malignancy. Understanding the distinctions between these skin lesions is crucial for appropriate diagnosis and management in clinical practice.
