Inflammatory conditions of the skin caused by allergy, infection, poor circulation, or exposure to chemical or environmental factors

(a)  

Chronic skin disease characterized by thicker than normal epidermal layer (stratum corneum) that sloughs to produce large, silvery scales; bleeding may occur if the scales are scraped away

(a)  

Development of patches of white skin where melanocytes are destroyed, apparently by an autoimmune response

(a)  

BACTERIAL INFECTION:

Small blisters containing pus; easily rupture to form a thick, yellowish crust; usually affects children

(a)  

BACTERIAL INFECTIONS:

Swollen patches in the skin caused by bacterium Streptococcus pyogenes

(a)  

BACTERIAL INFECTIONS:

Develop in people who are bedridden or confined to a wheelchair; compression of tissue and reduced circulation result in destruction of the skin and subcutaneous tissue, which later become infected by a bacteria, forming ulcers

(bedsores, pressure sores)

(a)  

BACTERIAL INFECTIONS:

Disorder of sebaceous glands and hair follicles that occurs when sloughed cells block the hair follicle, resulting in the formation of a lesion; the lesion may become infected and result in scarring

(a)  

BACTERIAL INFECTIONS:

appears to be affected by hormones, sebum, abnormal keratinization within hair follicles, and the bacterium Propionibacterium acnes

(a)  

VIRAL INFECTIONS:

Skin lesions; caused by a virus contracted through the respiratory tract; may develop into pneumonia or infect the brain, causing damage

(a)  

VIRAL INFECTIONS:

Skin lesions; usually mild viral disease contracted through the respiratory tract; may be dangerous if contracted during pregnancy because the virus can cross the placenta and damage the fetus

(a)  

VIRAL INFECTIONS:

Skin lesions; usually mild viral disease contracted through the respiratory tract

(a)  

VIRAL INFECTIONS:

Painful skin lesions; caused by the chickenpox virus after childhood infection; can recur when the dormant virus is activated by trauma, stress, or another illness

(a)  

VIRAL INFECTIONS:

Skin lesions; caused by herpes simplex I virus; transmitted by oral or respiratory routes; lesions recur

(a)  

VIRAL INFECTIONS:

Genital lesions; caused by herpes simplex II virus; transmitted by sexual contact

(a)  

Congenital disorder of the dermal capillaries
