Intertrigo describes a rash in the flexures or body folds, such as behind the ears, in the folds of the neck, under the arms (axillae), under a protruding abdomen, in the groin, between the buttocks, in the finger webs or toe spaces. Although intertrigo may affect one skin fold, it is common for it to involve multiple sites.*
Leg ulcers refer to full thickness skin loss on the leg or foot due to any cause. They occur in association with a range of disease processes, most commonly with blood circulation diseases.

A mole is a common benign skin lesion due to a local proliferation of pigment cells (melanocytes). It is more correctly called a melanocytic nevus and is sometimes also called a naevocytic nevus. A brown or black mole contains the pigment melanin, so may also be called a pigmented nevus.*
People who get this skin problem often see distinct, coin-shaped (nummular) or oval sores on their skin. They are usually itchy and can be cause by dry skin or an allergy.

Squamous cell carcinoma (SCC) is common form of keratinocytic skin cancer, usually related to exposure to ultraviolet radiation from sunlight.*
Vitiligo is an autoimmune skin disease where there is loss of pigment
An actinic keratosis is a scaly spot found on sun-damaged skin. It is also known as solar keratosis. It is considered precancerous.*
The term alopecia means hair loss. In alopecia areata, one or more round bald patches appear suddenly, most often on the scalp. Alopecia areata is also called autoimmune alopecia.*
Autoimmune disease is a wide variety of diseases caused by your own immune system turning on itself leading to many different health issues. Examples include lupus, scleroderma, thyroid problems, diabetes, alopecia, and more.
A benign tumor is a growth that is not cancerous. Depending on location and type of growth it may or may not need to be removed.
Infection of the soft tissue of the skin
Dry skin refers to skin that feels dry to touch. Dry skin is lacking moisture in the outer horny cell layer (stratum corneum) and this results in cracks in the skin surface. Dry skin is also called xerosis, xeroderma or asteatosis (lack of fat).*
Genital warts are caused by the HPV virus and can be considered a sexually transmitted disease. It can be treated by several different destruction modalities.

Lice are small insects that live on the human body. They are wingless and have six legs on which are attached strong claws that they use to grasp on tightly to hair shafts or clothing fibers. With their piercing mouthparts they puncture the skin to feed on human blood. They also inject saliva which causes itching. Lice can survive for up to 10 days without feeding if they become detached from their human host.
There are three types of lice that infest humans.
Pediculus humanus var. capitis – head lice
Pediculus humanus var. corporis – body lice
Phthirus pubis – pubic lice*
Melanoma is a potentially serious type of skin cancer, in which there is uncontrolled growth of melanocytes (pigment cells). Melanoma is sometimes called malignant melanoma.*

It is generally mild; very inflamed athlete’s foot is generally due to secondary bacterial infection.*
Basal cell carcinoma (BCC) is a common, locally invasive, keratinocytic, or non-melanoma, skin cancer. It is also known as rodent ulcer and basalioma. Patients with BCC often develop multiple primary tumors over time.*
Congenital nevi or birthmarks are essentially colored skin markings that develop before or shortly after birth. Nevi are sometimes called hamartomas, which are disordered proliferations of cells within the tissue of origin, and are due to developmental error.*

Keloid scars are firm, smooth, hard growths due to spontaneous scar formation. They can arise soon after an injury, or develop months later. Keloids may be uncomfortable or itchy, and may be much larger than the original wound. Keloids may form on any part of the body, although the upper chest and shoulders are especially prone to them. The precise reason that wound healing sometimes leads to keloid formation is under investigation but is not yet clear. While most people never form keloids, others develop them after minor injuries, burns, insect bites and acne spots. Dark skinned people form keloids more easily than Caucasians. Keloids are harmless to general health and do not change into skin cancers.*

A skin cancer is a tumor in which there is uncontrolled proliferation of any of the skin cells, whereas the normal process of regeneration of skin involves replication of the cells in a controlled fashion.
