| Erythema | Redness or inflammation of the skin. |
| Excoriation | surface layer injury caused by scratching or abrasion. |
| Furuncle | boil. Benign tumor of the skin raised, hard and shiny |
| Keloid. | Papillomatous growth occurring in many forms – worst Verruca. Pigmented congenital skin blemish that is usually benign but may become cancerous - Nevi. |
| Necrosis | dead tissue. |
| Nodule | An elevated, firm, solid circumscribed lesion; deeper in dermis than a papule; 1 to 2 cm in diameter. |
| Macule | a flat area that is a change in the color of the skin (freckles). |
| Papule - | elevated, firm area less than 1 cm in diameter. |

| Pustule | Elevated superficial lesion; similar to a vesicle but filled with purulent fluid. |
| Tinea pedis | athlete's foot. |
| Tumor | outgrowth of skin cells. |
| Layers of skin: | Epidermis, Dermis: Subcutaneous Layer |
| 1. Epidermis composed of three layers: | Stratum corneum,avascular,filled with keratin,makes the cells dry, tough and waterproof:Pigment layer, (Melanin):Stratum germinativum, New cells reproduced here replace cells of the stratum corneum |
| 2. Dermis | just below the epidermis layer: (a) Contains blood vessels, nerves, glands and hair follicles. (b) Cells are composed of connective tissue and elastic fibers. (c) Cells are bathed in interstitial fluid. |
| 3. Subcutaneous Layer | (a) adipose and loose connective tissue. (b)shape and contour to the body. (c) Primary functions include;Store water and fat,Insulation,Protection of the body organs,Provides a pathway for nerves and blood vessels |
| Malignant Melanoma | is a cancerous neoplasm in which pigment cells (melanocytes) invade the epidermis, dermis, sometimes the subcutaneous tissue. |
| The ABCD’s of Melanomas | A, Asymmetry (one half unlike the other). B, Border (irregularly scalloped or poorly circumscribed border). C, Color varied from one area to another; shades of tan and brown, black, and sometimes white, red or blue; change in shape, size, or color of mole |
| Vesicle: | circumscribed elevation of skin filled with serous fluid; smaller than 0.5 cm (chicken pox, herpes simplex, and herpes zoster). |
| Herpes simplex (Type I and II) | type I is characterized by a vesicle at the corner of the mouth, on the lips, or on the nose. type II is characterized as below the waist. |
| Chicken pox | is also characterized by vesicles on the body. |

| Pediculosis Corporis | caused by the body louse (found around the neck, waist, and thighs or the seams of the clothes); |
| Pediculosis Pubis | caused by the pubic louse (attached to the pubic hair, look like a crab). |
| Nits or lice can be seen on the body. | Pinpoint raised red macules, pinpoint hemorrhages, severe pruritus and excoriation confirm the diagnosis. |
| Topical application of a pediculicide | lindane (Kwell) or pyrethrins (RID) is used in the area of contamination to treat pediculosis. |

| Dermatitis Medicamentosa | occurs when a person is given a medication to which he is hypersensitive. |
| Contact Dermatitis | contact with agents in a person is hypersensitive. Common causes of contact dermatitis are: detergents, soap, industrial chemicals, plants such as poison ivy, poison oak. To avoid contact dermatitis causing agents, use gloves, protective gears, etc. In se |
| Paronychia | a disorder of the nails. The nails get soft or brittle, and the shape can change as they grow into the soft tissue (ingrown nails). |
| Impetigo | caused by Staphylococcus aureus, streptococcus, or a mixed bacterial invasion of the skin. The result is a highly contagious inflammatory disorders. |
| Impetigo | common in children. The lesions start as macules that develop into pustulant vesicles. Affected areas are the face, hands, arms, and legs. Honey colored dried exudate form from the pustulant lesions ranges in size from pinpoint to the size of a nickel. |

| (1) Sudoriferous (sweat) glands: | (a) Tube-like structures located in the dermis and subcutaneous layers. (b) Excretion of sweat helps cool the body surface and. (c) Rid the body of waste products such as uric acid, ammonia and other products. |
| (2) Ceruminous glands: | (a) Secrete a waxlike substance called cerumen. (b) Located in the external ear canal. |
| (3) Sebaceous (oil) glands: | (a) Secrete sebum through the hair follicles. (b) Function is to lubricate the skin and hair. (c) Sebum also inhibits bacterial growth. |
| (4) Hair: | composed of modified dead epidermal tissue (keratin). |
| (5) Nails: | composed of tightly packed keratin. |
| In Paronychia, | an infection of the nail develops and spreads around the nail, thus giving it the nickname “runaround.” Application of wet dressings or topical antibiotics may be used. Sometimes a surgical incision and drainage of the infected area are performed. |

| Nursing intervention should be | the application of the medication to rid the pt of the lice. |
| Basal Cell Carcinoma | occurs thru the contact with certain chemicals, overexposure to the sun, and radiation treatment. |
| Basal Cell Carcinomas arise in the basal cell layer of | the epidermis. |
| Basal Cell Carcinomas arise in the basal cell layer | Often found on the face and upper trunk, usually scaly in appearance, and metastasis is rare. |
| Fair people are more susceptible, because they have less melanin on the skin surface. | Basal Cell Carcinomas |
| Squamous Cell Carcinoma | occurs on the sun-exposed areas of head, neck, and lower lip, and arises in the epidermis layer. |
| This cancerous neoplasm is a firm, nodular lesion topped with a crust or a central area of ulceration. | Squamous Cell Carcinoma |
| Squamous Cell Carcinoma | can metastasize quickly comparing to Basal Cell Carcinoma via the lymphatic system. |
| Herpes simplex virus as well as chickenpox is characterized by these lesions | Vesicles. The same virus Herpesvirus hominis causes herpes 1, 2. |
| This virus nicknamed as “cold sore” is usually passed with direct contact to face | Herpes Simplex 1. Herpes |
| Simplex type 2 | also called genital herpes occurs through sexual contact. |
| Herpes zoster (shingles) is caused by | same virus that causes chickenpox (varicella) (Herpes varicellae). |
| Herpes 1, 2 and herpes zoster (shingles) is treated by | Zovirax (Acyclovir) as an antivirus agent. |
| The lesions are located along the nerve fibers of spinal ganglia. | Herpes 1, 2 and herpes zoster (shingles) |
