The common sites are the feet and the hands. The type of callus that develops a hard core which   is a whitish, corn-like central kernel is called a corn. 2. Keloid: - Hypertrophied, thickened scar after trauma or surgical incision. These occur from excessive collagen formation in the corium during connective tissue repair. Here kelis means a blemish which comes from the Greek word. 3. Keratosis: - Area of the epidermis which is thickened. Due to excessive exposure to light or actinic keratosis, some keratosis appear red. Seborrhcic keratoses look yellow or brown and are also called senile warts. These both types occur in middle age and old age. 4. Leukoplakia: - On mucous membrane tissue of the tongue or cheek, there appears white, thickened patches. This is a precancerous lesion.

Scabies is often spread through commonly affected and sexual contact, areas are the penis, groin, nipples and skin between the fingers. The treatment for this is topical medicated cream to destroy the scabies mites (tiny parasites). 9. Scleroderma: - A chronic progressive disease of the skin with hardening and shrinking of connective tissue. Fibrous scar tissue infiltrates the skin and heart, lungs, kidney, and esophagus may be affected as well. Skin is thickened, hard, and rigid, and pigmented patches may occur. Etiology is not known so much; palliative treatment consists of drugs, such as immunosuppressives and anti-inflammatory agents, and physical therapy. 10.

The examples are dry heat (fire), moist heat (steam or liquid), chemicals, electricity, radiation or lightning. These burns are classified into three types. First-degree burns: - These burns are superficial epidermal lesions, erythema, blisters, and hyperesthesis are the first-degree burns examples. Sunburn is an example of this type of burns. Second-degree burns: - These burns are epidermal and dermal lesions, erythema, blisters and hyperesthesia. Third-degree burns: - These burns of which epidermis and dermis are destroyed (necrosis of skin), and subcutaneous layer is damaged leaving charged while tissue. 3.

Pruritus: - This means itching. Pruritus is associated with most forms of dermatitis and with other conditions as well. It arises as a result of stimulation of nerves in the skin by enzymes released in allergic reactions or by irritation caused by substances from the blood or from foreign bodies. 14.
