Which lesion type is described as a plateau-like lesion greater than 10 mm?

Explanation:
The concept here is how skin lesions are classified by elevation and size. A plaque is a raised lesion with a broad, flat top (plateau-like) and a size greater than 1 cm (10 mm). That combination—flat-topped, plateau-like surface and a size over 1 cm—matches the description given. Other lesion types don’t fit as well: a vesicle or pustule is smaller and fluid-filled, not a broad flat top. A nodule is a solid lesion that extends more deeply and tends to be dome- or rounded-backed rather than flat-topped. A papule is raised but typically under 1 cm, not large enough to be a plaque. A macule or patch is flat and not elevated at all.
