GENERAL HISTOLOGY

Detailed explanation-1: -Second-degree (partial-thickness) burns-Second-degree burns (also called partial-thickness burns) involve the top two layers of skin. These burns form blisters, are very painful, may seep fluid, and blanch when pressed (picture 2). Second-degree burns typically heal within 7 to 21 days.

Detailed explanation-2: -Partial-thickness burns (was second degree) involve the epidermis and portions of the dermis. They are characterized as either superficial or deep. Full-thickness burns (was third degree) extend through and destroy all layers of the dermis and often injure the underlying subcutaneous tissue.

Detailed explanation-3: -2nd-degree burn. This type of burn affects both the epidermis and the second layer of skin (dermis). It may cause swelling and red, white or splotchy skin. Blisters may develop, and pain can be severe. Deep second-degree burns can cause scarring.

Detailed explanation-4: -Depending on the depth of the wound, second degree burns can take anywhere from one week to several months to heal. Superficial second degree burn wounds can take from 7-21 days to form the first layer of fragile new skin. This new skin can then take another one to two months to mature back to usual thickness.
