Disorders of the Integumentary System

Infection caused by bacteria

Impetigo

The highly contagious bacterial infection known as impetigo is most frequently brought on by the staphylococcus aureus bacteria.

It begins with small pustules on the skin's surface, most often found around the mouth and nose. It is common in children and people whose immune systems are compromised, as it is transmitted through direct contact.

Cellulitis Cellulitis is an infection that spreads through the body that is caused by anaerobic bacteria such as streptococcus pyogenes and clostridium perfringens. These bacteria enter the body through cuts in the skin.

The production of enzymes that degrade the connective tissue that, in most cases, serves to separate an area of inflammation from the rest of the body helps facilitate their spread.

If treatment is not administered, the bacteria could enter the bloodstream and cause septicemia.

Infection Caused by Fungi

Tinea and ringworm of the foot

These are infections that only affect the top layer of the skin.

An infection known as ringworm causes an inflammatory ring to spread outward in all directions. This condition, which most

commonly affects the scalp, feet, and groin area, is also very contagious.

Tinea pedis (athlete’s foot) affects the skin.

Viral Infection

Human papillomavirus (HPV)

HPV is the virus that produces warts and verrucas, which are contagious and spread through direct contact. This results in an increase in the number of epidermal cells and the creation of a tiny, hard growth, which is almost never harmful.

Herpesviruses

The herpes zoster virus is responsible for the rash that appears in both chickenpox and shingles.

Herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) are the viruses responsible for cold sores and genital herpes, respectively.

Inflammatory diseases

Eczema (Dermatitis)

Eczema is a common skin condition that is characterized by inflammation and can either be acute or persistent.

The symptoms of acute dermatitis include redness, swelling, and the exudation of serous fluid. These symptoms are typically accompanied by pruritus (itching), and they ultimately lead to crusting and scaling of the skin.

Malignant melanoma

A malignant melanoma is a cancer that is caused by the uncontrolled growth of melanocyte cells. It typically begins in a mole that becomes larger and may have an uneven border.

Ulceration and bleeding of the melanocytes is most typically seen in young and middle-aged adults but can occur in people of any age.

This tumor develops as a result of repetitive periods of intense exposure to sunlight, including numerous episodes of sunburn, particularly during childhood. The sunburns are a particularly important factor in the development of this tumor.
