What type of skin lesion is characterized as a benign, pigmented epidermal tumor with a stuck-on appearance?

The correct answer is characterized by a benign nature and a distinctive appearance that resembles being "stuck on" the skin. This description fits seborrheic keratosis, which typically presents as a raised, wart-like lesion that may vary in color from light tan to black.

These lesions are common in older adults and are not precancerous, distinguishing them from other types of skin lesions that may indicate more serious conditions. The "stuck-on" look is due to the thick, scaly surface that often results from the accumulation of keratin. In contrast, other options like basal cell carcinoma are malignant and can present with ulceration or crusting, while a mole (nevus) typically does not have the same appearance and is often more uniformly colored. Actinic keratosis, although also a benign lesion, usually presents with a rough, scaly patch and has the potential to progress to squamous cell carcinoma, making it different from seborrheic keratosis.
