It is often difficult to visually distinguish basal-cell cancer from acne scar, actinic elastosis, and recent cryodestruction inflammation. [14]
In all types, some increased fragility occurs, but the degree varies depending on the underlying subtype. The skin may tear and bruise easily, and may heal with abnormal atrophic scars; [45] atrophic scars that look like cigarette paper are a sign seen including in those whose skin might appear otherwise normal.
Mature scars are usually thick, collagenous bundles arranged horizontally with paucicellularity, vertical blood vessels, and no appendages. [3] This is distinguished from desmoplasia in the organization of the tissue, the appendages, and orientation of blood vessels. Immature scars are more difficult to distinguish due to their neoplastic ...
