Rash: Breaking out (eruption) of the skin. A rash can be caused by an underlying medical condition, hormonal cycles, allergies, or contact with irritating substances. Treatment depends on the underlying cause of the rash. Medically, a rash is referred to as an exanthem. Some common skin rashes are:

Shingles: Shingles (herpes zoster) occurs when the dormant chickenpox virus (varicella-zoster) is reactivated in your nerve tissues. Early signs of shingles include tingling and localized pain. Most, but not all, people with shingles develop a blistering rash. Typically, the shingles rash lasts two to four weeks, and most people make a complete recovery.

Mouth Ulcers: Canker sores or mouth ulcers are normally small lesions that develop in your mouth or at the base of your gums. They are annoying and can make eating, drinking, and talking uncomfortable. Factors that can put you at risk for developing mouth ulcers are being a woman or having a family history of mouth ulcers.
Mouth ulcers are not contagious and usually go away within a week. However, if you get a canker sore that is large or extremely painful or if it lasts for a long time without healing, you should seek the care of a physician.

Pemphigoid: Pemphigoid is a rare autoimmune disorder that can develop at any age, but that most often affects the elderly. Pemphigoid is caused by a malfunction of the immune system and results in skin rashes and blistering on the legs, arms, and abdomen. Pemphigoid can also cause blistering on the mucous membranes of the eyes, nose, mouth, and vagina, and can occur during pregnancy in some women. There is no cure for pemphigoid, but there are many treatment options.

Tinea Versicolor: The fungus Pityrosporum ovale is a nonharmful type of yeast that is found on the surface of the skin. It normally does not cause any health problems. However, sometimes this yeast begins to grow out of control, affecting the pigmentation (natural color) of your skin. When this happens, you may develop patches of skin that are lighter or darker. This condition is known as tinea versicolor or pityriasis versicolor.

Eczema: Eczema is a common skin condition marked itchy and inflamed patches of skin. It is also known as atopic dermatitis. It is more common in babies and young children. It occurs on the faces of infants, as well as inside the elbows and behind the knees of children, teenagers, and adults. It is caused by an overactive immune system. Up to 20 percent of children and one to three percent of adults develop atopic dermatitis, according to the American Academy of Dermatology. In rare cases, atopic dermatitis can first appear during puberty or adulthood. It affects males and females equally.

Corns and Calluses: Corns and calluses are the terms given to patches of hard, thickened skin. These can be located anywhere on your body, but they are typically found on your feet.
Corns are small, round circles of thick skin. They can develop on any area of your foot, but they are most commonly found on the tops and sides of your toes and on the sole of your foot. They occur more frequently on bony feet that lack cushioning.
Calluses are rough, very hard patches of skin. They are usually found on the heel or the ball of your foot, but they can also be found on your hands and knuckles. Calluses are usually bigger than corns and have a yellow color. They lack well-defined edges and may lack sensitivity compared to the rest of the foot.

Stasis Dermatitis And Ulcers: Stasis dermatitis is skin inflammation caused by blood pooling in the veins in your legs. Pooling of blood in the veins of the legs is called venous insufficiency or venous stasis.
Venous pooling causes the pressure inside the veins to be higher than normal (venous hypertension). This elevated pressure in the veins causes damage to your capillaries. When capillaries are damaged, a protein called fibrinogen leaks out into your tissues. Your body converts fibrinogen to fibrin. The buildup of fibrin (fibrin cuffs) is thought to cause a decrease in oxygen supply to the skin, resulting in cell death. This inflammatory process causes your skin to change in its appearance.
Stasis dermatitis is a chronic condition that can cause considerable discomfort. This condition is most likely to occur in people over the age of 50. About six to seven percent of people in that age group have stasis dermatitis. Incidence of this condition may be as high as 20 percent in those over age 70. Women are slightly more likely than men to have stasis dermatitis. This is thought to be due to increased stress on leg veins caused by pregnancy.

Actinic Keratosis: If you’ve spent a lot of time outside under the sun, you’ll probably start to notice brown spots appearing on your hands and arms as you get older. Sometimes called sun spots or age spots, the correct term for this condition is actinic keratosis. The spots themselves are called actinic keratoses.

Actinic keratosis (AK) is a very common skin condition. It occurs when skin cells called keratinocytes start to grow abnormally, forming scaly discolored spots. The skin patches may be brown, tan, grey, or pink. They tend to appear on the parts of the body that get the most sun exposure such as the hands, arms, face, scalp, and neck.
AK may actually be in situ stage squamous cell carcinoma (SCC) lesions. “In situ” means the lesions are confined to one location and not invading other tissue. In most cases, AK lesions are relatively benign. However, each lesion has about a 10 percent chance of progressing into an invasive form of SCC. Because of this risk, the spots should be monitored regularly for any suspicious changes.

Lichen Planus: Lichen planus is a fairly common skin rash that is thought to be triggered by the immune system. Exactly why the immune response occurs is not known. There may be several contributing factors, and each case is different. Potential causes include viral infections, an allergen, or even stress or genetics. Sometimes lichen planus occurs along with autoimmune disorders.
While it may be uncomfortable, in most cases lichen planus is not a serious condition. It is not contagious. There are some rare variations of the condition that are more serious and painful. It can be treated by using topical and oral medications to reduce symptoms, or by using drugs that suppress the immune system.

Keloids: When skin is injured, fibrous tissue (called scar tissue) forms over the wound to repair and protect the injury. In some cases, scar tissue grows excessively, forming smooth, hard growths called keloids. Keloids can be much larger than the original wound, and are most commonly found on the upper chest and shoulders. However, keloids can affect any part of the body.
