What skin condition is noted for having a "stuck-on" appearance?

Seborrheic keratosis is characterized by its "stuck-on" appearance, which refers to the way the lesions appear to be adherent to the skin surface, resembling coins or plaques that have been stuck onto the skin. These benign tumors of the epidermis often have a rough, scaly texture and can vary in color from light tan to dark brown or black. They are commonly found in older adults and typically appear on the trunk, face, scalp, and other areas of the body.

The term "stuck-on" captures the essence of these lesions, as they do not peel off easily and give the impression that they are deposited onto the skin rather than being an integral part of it. Recognizing this appearance is important for differentiation from other skin conditions that may present with similar contexts but have distinct features and implications.

In contrast, actinic keratosis presents as rough, scaly patches often associated with sun damage, while psoriasis leads to well-demarcated red plaques covered with silvery scales. Eczema, on the other hand, is typically characterized by inflamed, itchy, and sometimes oozy areas, lacking the smooth, wart-like appearance of seborrheic keratosis.
