The integumentary system is made up of the hair, nails, and the largest organ in the human body, the skin. It has many functions such as protect other organs, obtain water, and excrete toxins, thus the diseases may be very harmful. The integumentary system has five very common diseases. They include, Alopecia Areata, Psoriasis, Warts, Dermatitis or Eczema, and Athlete’s Foot. Only two out of the five are contagious, but all are or can become severe if not treated immediately or properly.
Alopecia Areata, also called spot baldness, is an autoimmune disorder. In this case, the immune system attacks the hair follicles all over the body and can lead to baldness. It typically starts in the early childhood stages or the adolescent years. However, it can appear at any age during any part of one’s lifetime. Only about 0.1%-0.2% of all males and females have this disease and it is not contagious.

Psoriasis is a non-contagious chronic autoimmune disease. People who have been diagnosed will frequently have red and scaly lesions on parts of his or her skin. These lesions are called psoriatic plaques. They show areas of inflammation and increased skin production. Excessive production of skin cells results in the accumulation of silvery-white cells, which are the plaques. Most of the time, the plaques are found on the elbows and knees, but can affect the scalp and genitals.

Warts come from the Human Papilloma Virus, thus resulting in many different forms of warts. They appear usually on the hands and feet and can be described as tiny, round, rough tumors that are a solid blister. Some different types of warts are the common wart, flat wart, plantar wart, genital wart, and mosaic wart. Warts are very contagious because of how it is spread; via direct contact. They usually disappear after a couple of months and if not they can be easily and safely removed.

Dermatitis is a disease in which inflammation of the skin occurs. There are many types of Dermatitis including, seborrheic dermatitis and atopic dermatitis, also known as Eczema. Effects of this disease come in various forms. It may start out as an itchy rash and then spread and increase in redness or swelling. This disease is not threatening or contagious but can make one feel uncomfortable and feel self-conscious about one’s self.

Athlete’s Foot, or tinea pedis, is a fungal infection that causes scaling, flaking, and itching in different areas of the skin. This disease is contagious, mostly in moist areas where people would walk barefoot such as in a public bath house or shower room. It usually starts out on the feet because of how it’s transmitted, but can spread to areas such as the groin. By maintaining good hygiene, one could easily avoid this disease.
