Eccrine sweat gland
Most numerous sweat-producing exocrine gland in the skin.
Outermost layer of the skin.
Layer of the skin cells forming the outer and inner surfaces of the body.
Sac within which the hair grows.
The skin and its accessory structures such as hair and nails.
Hard protein material found in the epidermis, hair, and nails. Keratin means horn and commonly is found in the horns of animals.
The half-moon-shaped, whitish area at the base of a nail.
Skin pigment. It is formed by melanocytes in the epidermis. Eumelanin is brown-black pigment, while pheomelanin is red-yellow.
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 sebaceous glands.
Flat, scale-like cells composing the epidermis.
Arranged in layers
Stratum (plural: Strata)
A layer (of cells).
Outermost layer of the epidermis, which consists of flattened, keratinized cells.
Innermost layer of the skin, containing fat tissue.
dry, scaly (fish-like)
fungus(fungi including yeasts, molds, and mushrooms)
hair, hair follicle
sebum (oily secretion from sebaceous glands)
an area of abnormal tissue anywhere on or in the body.
Collection o dried serum and cellular debris
Thick-walled, closed sac or pouch containing fluid or semisolid material.
Wearing away or loss of epidermis.
Groove or crack-like sore.
Flat lesion measuring less than 1 cm in diameter.
Solid, round or oval elevated lesion 1 cm or more in diameter.
Small ((less than 1 cm in diameter), solid elevation of the skin.
Growth extending from the surface of mucous membrane.
Papule containing pus.
Open sore on the skin or mucous membranes (deeper than an erosion).
Small collection (papule) of clear Fluid (serum); blister.
Smooth, edematous (swollen) papule or plaque that is redder or paler than the surrounding skin.
black (as coal)
Chronic papular and pustular eruption of the skin with increased production of sebum.
Injury to tissue caused by heat contact.
diffuse, acute infection of the skin marked by local heat, redness, pain, and swelling.
Eczema (atopic dermatitis)
Inflammatory skin disease with erythematous, papulovesicular, or papalosquamous lesions.
Exanthematous viral diseases
Rash (exanthem) of the skin due to a viral infection.
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.
Contagious, parasitic infection of the skin with intense pruritus.
Chronic progressive disease of the skin and internal organs with hardening and shrinking of connective tissue.
Systemic lupus erythematosus (SLE)
Chronic autoimmune inflammatory disease of collagen in skin, joints, and internal organs.
Infection of the skin caused by a fungus.
Acute allergic reaction in which red, round wheals develop on the skin.
Loss of pigment (depigmentation) in areas of the skin (milk-white patches). Michael Jackson disease...
Basal cell carcinoma
Malignant tumor of the basal cell layer of the epidermis.
Squamous cell carcinoma
Malignant tumor of the squamous epithelial cell in the epidermis.
Cancerous growth composed of melanocytes.
