apocrine sweat gland
One of the large dermal exocrine glands located in the axilla and genital areas. It secretes sweat that, in action with bacteria, is responsible for human body odor.

Middle layer of skin
eccrine sweat gland
Most numerous sweat-producing exocrine gland in the skin.
outermost layer of skin
Layer of skin cells forming the outer and inner surfaces of the body
Sac within which each hair grows.
the skin and its accessory structures such as hair and nails.
Hard protein material found in the epidermis, hair, and nails.
A fat cell
Half-moon-shaped, whitish area at the base of a nail.
Major skin pigment. It is formed by melanocytes in the epidermis.
Soft tissue surrounding the nail border
Tiny opening on the surface of the skin
Oil-secreting gland in the dermis that is associated with hair follicles
oily substance secreted by the sebaceous glands
Flat, scale-like cells composing the epidermis.
Arranged in layers
a layer of cells
Outermost layer of the epidermis, which consists of flattened, keratinized (horny) cells.
The innermost layer of the skin, containing fat tissue
Collection of dried serum and cellular debris.
Thick-walled, closed sac or pouch containing fluid or semisolid material.
Wearing away or loss of the epidermis.
Groove or crack-like sore
Discolored (often reddened) flat lesion.
Solid round or oval elevated lesion more then 1 cm in diameter.
Small (less than 1 cm in diameter), solid elevation of the skin (pimples).
Benign growth extending from the surface of mucous membrane
Small elevation of the skin containing pus.
Open sore on the skin or mucous membranes within the body.
Small collection of clear fluid (serum); blister.
Smooth, slightly elevated, edematous (swollen) area that is redder or paler than the surrounding skin.
Absence of hair from areas where it normally grows.
Bluish-black mark (bruise) on the skin.
Small, pinpoint hemorrhages
acute allergic reaction in which red, round wheals develop on the skin
Chronic papular and pustular eruption of the skin with increased production of sebum.
Buildup of sebum and keratin in pores of the skin.
Sebum plug partially blocking the pore.
Pore becomes completely blocked.
Injury to tissues caused by heat contact.
first degree burn
superficial epidermal lesions, erythema, hyperesthesia, and no blisters. Sunburn is an example.
second degree burn
Epidermal and dermal lesions, erythema, blisters and hyperesthesia.
third degree burn
Epidermis and dermis are destroyed (necrosis of skin) and subcutaneous layer is damaged, leaving charred white tissue.
Diffuse acute infection of the skin marked by local redness pain and swelling.
Inflammatory skin disease with erythematous, papulovesicular lesions.
exanthematous viral disease
Rash (exanthema) of the skin due to a viral infection. E.g. are rubella (German measles), rubeola (measles), and varicella (chickenpox).
death of tissue associated with loss of blood supply
Bacterial inflammatory skin disease characterized by vesicles, pustules, and crusted-over lesions.
chronic, recurrent dermatosis marked by itchy, scaly, red plaques covered by silvery gray scales
a contagious, parasitic infection of the skin with intense pruritus
a chronic progressive disease of the skin with hardening and shrinking of connective tissue
systemic lupus erythematosus
chronic autoimmune inflammatory disease of collagen in the skin, of joints, and of internal organs
infection of the skin caused by a fungus
fungal infection of the scalp
Affects the skin under the beard
A fungus of the nails.
Loss of pigment (depigmentation) in areas of the skin. (Milky white patches)
Increase growth of cells in the keratin layer of the epidermis caused by pressure or friction.
hypertrophied, thickened scar that occurs after trauma or surgical incision
Thickened and reddened area of the epidermis, usually associated with aging or skin damage.
White, thickened patches on mucous membrane tissue of the tongue or cheek.
pigmented lesion of the skin
epidermal growth caused by a virus, such as plantar warts, juvenile warts and venereal warts.
squamous cell carcinoma
Malignant tumor of the squamous epithelial cells of the epidermis.
cancerous growth composed of melanocytes
Malignant vascular neoplastic growth caracterized by cutaneous nodules.
basal cell carcinoma
a malignant tumor of the basal layer of the epidermis
use of subfreezing temperature via liquid nitrogren appication to destroy tissue
use of a sharp dermal curette to scrape away a skin lesion
Tissue is destroyed by burning with an electric spark.
thin layers of a malignant growth are removed, and each is examined under a microscope
suspected malignant skin lesions are removed and sent to the pathology laboratory for microscopic examination
Reaction of the body to a substance by observing the results of injecting the substance intradermally (within the dermis) or applying it topically to the skin.
samples of skin are sent to a laboratory to detect presence of microoganisms
Scrapings from skin lesions, hair specimens, or nail clippings are sent to a laboratory for culture and microscopic examination.
Infection caused by a yeast that typically affects the moucous membranes, vaginal mucosa and skin.
