(A) Wound at 24 h (100×) remains open and an inflammatory cell infiltrate is present (open arrow). (B) Magnified view (200×) of the same incompletely healed wound at 24 h. (C) Wound at 72 h (100×) has no epidermal appendages, consistent with adult-type repair and scar formation. (D) Magnified view (200×) of the wound shown in the (C) demonstrating an inflammatory cell infiltrate and lack of dermal appendages.
