Scar

• Loss of normal papillary dermis and reticular dermis contrast

• Single homogenous hyperreflective texture corresponding to densely packed collagen bundles minimal fluid

• Fine vessels may be evident in healing scars

• Can occur with a hyporeflective area underneath scar indicating perivascular lymphocytic infiltrate (*)

• Similar to scar tissue healed biopsy sites have increased dermal collagen hyperreflectivity and a more homogenous texture

• Typical skin structures: hair follicles, glands and vessels are typically absent, however fine vessel structures may occur

• Biopsy scars typically appear as hyperreflective wedges in the dermis further indicated by the change in collagen texture
