Boils | also called furuncles, are local infections of the skin, often at hair shafts. typi- cally occur one at a time, a group connected by channels under the skin is called a carbuncle. |
Methicillin-resistant Staphylococcus aureus (MRSA) | a group of infection-causing staph bacteria that have been recognized in hospital settings since the 1950s and are now common outside of healthcare facilities |
Hidradenitis suppurativa | deep boils that occur where hair follicles and apocrine weat glands are numberous, typically the axilla and groin |
Pilonidal cysts | a large encysted infection at the sacrococcygeal region |
Necrotizing fasciitis | "flesh-eating bateria" cause circulatory shock and death. Moves quickly along fascial planes and can progress from a minor skin would to a limb-threatening or life-threatening infection in a matter of hours |
Impetigo | highly infections; causes many seeping blisters that itch and crust over. Seen in young children often but can affect adults |
Herpes simplex | type 1 (HSV-1) has traditionally been associated with lesions that appear around the mouth, while type 2 (HSV-2) is associated with genitals |
Warts | known as verruca vulgaris, are small, benign growths caused by varieties of human papillomavirus (HPV) that invade keratinocytes deep in the stratum basale of skin and some mucous membranes |
Acne rosacea | an idiopathic chronic skin condition. It affects the face, especially the middle third (the nose and cheeks) |
Acne vulgaris | a condition in which a person developsmany small, localized skin lesions in the pilosebaceousunits (sebaceous glands and the hair follicles that they lubricate) |
Eczema | itching, redness, and scalling skin connected to immune dysfunction and hypersensitivity reactions |
Seborrheic keratosis | a benign skin growth in which epithelial cells proliferate in isolated areas |
Skin cancer | the uncontrolled replication of cells of the skin that damage nearby tissues |
Melanoma | cancer in melanocyte cells deep in the epidermis |
Burns | tissue damage from heat, cold, electricity, chemicals, friction, and radiation. Measured in as 1st, 2nd, and 3rd degree |
Pressure injuries | inadequate blood flow to skin that is compressed for prolonged periods. includes decubitus ulcers, bedsores, pressure sores, and trophic ulcers |

Tinea manuum | fungal infection of the hands |
Basal Cell Carcinoma | the most common type of skin cancer, accounting for about 80% of all nonmelanoma skin cancer diagnoses. It is a slow-growing tumor of basal cells in the epidermis |
Squamous Cell Carcinoma | cancer of skin cells that arises in keratinocytessuperficial to the basal layer. |
