skin
percutaneous
pertaining to through the skin
abscess
localized collection of pus
cellulitis
inflammation of the skin and subcutaneous tissue caused by infection; characterized by redness, pain, heat, and swelling
impetigo
superficial skin infection characterized by pustules and caused by either staphylococci or streptococci
MRSA
invasion of body tissue by methicillin-resistant Staphylococcus aureus, a strain of common bacteria that has developed resistance to methicillin and other antibiotics. It can produce skin and soft tissue infections and sometimes bloodstream infections and pneumonia, which can be fatal if not treated. MRSA is quite common in hospitals and long-term care facilities but is increasingly emerging as an important infection in the general population.
rosacea
chronic disorder of the skin that produces erythema, papules, pustules, and abnormal dilation of tiny blood vessels, usually occurring in the central area of the face in people older than 30 years
squamous cell carcinoma (SCC)
malignant growth developing from scale like epithelial tissue of the surface layer of the epidermis; it invades local tissue and may metastasize. While most commonly appearing on the skin, SCC can occur in other parts of the body including the mouth, lips, and genitals. The most frequent cause is exposure to sunlight.
systemic lupus erythematosus (SLE)
chronic inflammatory disease involving the skin, joints, kidneys, and nervous system. This autoimmune disease is characterized by periods of remission and exacerbations. It also may affect other organs.
actinic keratosis
precancerous skin condition of horny tissue formation that results from excessive exposure to sunlight. It may evolve into a squamous cell carcinoma.
scleroderma
disease characterized by chronic hardening (induration) of the connective tissue of the skin and other body organs
biopsy
view of life (the removal of living tissue from the body to be viewed under the microscope)
leukoderma
white skin (white patches caused by depigmentation)
necrosis
abnormal condition of death (cells and tissue die because of disease)
alopecia
loss of hair
cyst
closed sac containing fluid or semisolid material
cytomegalovirus (CMV)
herpes-type virus that usually causes disease when the immune system is compromised
edema
puffy swelling of tissue from the accumulation of fluid
pallor
paleness
diaphoresis
sweating
ulcer
erosion of the skin or mucous membrane
vesicle
small elevation of the epidermis containing liquid (also called blister)
verruca
circumscribed cutaneous elevation caused by a virus (also called wart)
cauterization
destruction of tissue with a hot or cold instrument, electric current, or caustic substance (also called cautery)
urticaria
itchy skin eruption composed of wheals of varying sizes and shapes. Urticaria is sometimes associated
with infections and with allergic reactions to food, medicine, or other agents. Other causes include
internal disease, physical stimuli, and genetic disorders. (also called hives)
laceration
torn, ragged-edged wound
Kaposi sarcoma
cancerous condition starting as purple or brown papules on the lower extremities that spreads through
the skin to the lymph nodes and internal organs; frequently seen with AIDS
contusion
injury with no break in the skin, characterized by pain, swelling, and discoloration (also called a bruise)
basal cell carcinoma (BCC)
malignant epithelial tumor arising from the bottom layer of the epidermis called the basal layer; it
seldom metastasizes, but invades local tissue and may recur in the same location. Common in
individuals who have had excessive sun exposure.
-ectomy
excision or surgical removal
-rrhea
flow, discharge
