This presents as large, depressed, "cliff-drop" bordered patches of atrophy without the characteristic herniation or "buttonhole" sign of anetoderma.
This condition results in diffuse, fine wrinkling of the skin, particularly on the trunk, rather than the discrete, sac-like protrusions of anetoderma.
These are multiple, small, non-herniating, whitish papules, unlike the larger, reducible, outpouching lesions of anetoderma.
A scar is typically firm and fibrotic, often from a known injury, whereas an anetoderma lesion is a soft, flaccid protrusion of skin due to a loss of elastic tissue.
