In identifying a benign skin lesion that appears as "stuck on," which diagnosis is most appropriate?

Seborrheic keratosis is most appropriate to identify as a benign skin lesion that appears "stuck on." This characteristic appearance is typical for seborrheic keratoses, which are common, non-cancerous growths on the skin, often resembling a wart or a piece of wax that has been applied to the skin.

These lesions can vary in color from light tan to black and are generally raised with a rough, scaly surface, contributing to the "stuck on" look that differentiates them from other lesions. They typically occur in older adults and can be found on various body parts, including the chest, back, and face.

In contrast, basal cell carcinoma is a type of skin cancer that usually presents as a pearly or waxy bump rather than appearing "stuck on." Hemangiomas are benign vascular tumors that have a distinct red or purple color and do not share the same texture or appearance. Achrocordons, or skin tags, are small, soft, benign growths that often hang off the skin, also not exhibiting the "stuck on" appearance typical of seborrheic keratosis.
