Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.
Calluses and corns may heal by themselves eventually, once the irritation is consistently avoided. They may also be dissolved with keratolytic agents containing salicylic acid , sanded down with a pumice stone or silicon carbide sandpaper or filed down with a callus shaver , or pared down by a professional such as a podiatrist .
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
However, this white skin should not be confused with the pale, whitish appearance of the new epithelial tissue in a healing wound. Although most maceration clears up quickly once the skin is exposed to fresh air and allowed to dry, sometimes skin that experiences long periods of maceration is vulnerable to fungal and bacterial infection .
In the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
Chronic ulcer symptoms usually include increasing pain, friable granulation tissue, foul odour, and wound breakdown instead of healing. [3] Symptoms tend to worsen once the wound has become infected. Venous skin ulcers that may appear on the lower leg, above the calf or on the lower ankle usually cause achy and swollen legs.

Clavus papillari – a painful corn surrounded by a white border, which is either bruised or gelatinous tissue Clavus neurofibrosus (or fibrosus ) – an old, deep scarred corn (in a crater with a white, sometimes macerated border) that is traversed by nerves and connective tissue, thought to be scar tissue caused by chronic low-grade inflammation.
