vesicle
vesicle >1cm

elevated superficial similiar to vesicle but full of purulent fluid
postule
elevated circumscribed encapsulated lesion w/ fluid or semi solid
cyst
fine irregular red line by capillary dilation
telangiectasia
keratinized cell, flaky, dry, oily, thick
scale
irregular shaped elevated progressive scar grows beyond wound
cause by excess collagen upon healing

loss of epi/dermis concave in size
ulcer
plug of sebaceous and keratin lodged in opening of hair follicle
comedome

burrow
itching of skin disorder
pruritis
delayed cell mediated hypersensitivity

burn complication
pediculosis fungal infection bacterial infection acne viral infection
dermatological infection
head,body,pubic itch
comfort itch
pinpoint erythema, raised macule
cause- crowded places, hygiene
pediculosis
assess allergy
remove stinger
puncture wound
stings
identify spider if possible,
appear as macule or papule unless toxic
spider bite
hard to distinguish
usually still attached
dont transfer if <24 hours
risk: rocky mountain fever, spotted disease

poor hygiene/contaminated barber tool.
hair/lash, brow/
Tinea Capitis
general location
round, scaling
tinea corpitis
most common
cause by moisture/ ahtletes foot
tinea pedis

golden crust
secondary infection
Risk: suburn/large open area
highly contageous
impetigo
infection of hair follicle inclean or chemical irritation, red bump
folliculitis
Deep infected folliculitis-boil
involves many follicles
risk: obese poor nourished immune suppressed. can recur due to core
can rupture and keep drainage from spreading
furuncles and carbuncles
tissue inflammation and infection
hot/red
staph.strep
cellulitis
enlarged lymp nodes
potential sepsis
lymphadenopathy.lymphangitis
sebaceous gland stimulate by androgen
meds cause sun sensitivity
acne vulgaris
20-50 year olds
follicular eruption
sun exposure
acne rosacea
warts HPV herpes zorelzester smallpox rubella
viral infections
virus cause overgrowth of cells
HPV
viral infection
1: pass by kissing, oral fluid
2; genital contact
Type 1; oral tranmission- cold sore, encephalitis
type 2; genital herpes-cagina/penis/birth
Herpes simplex 1& 2
open lesions leads to chicken pox

bullous disease (blistering)
light skin, sun exposed, pink to tan
local invasion bleeding and hemmorhage

indurated with inflammed base
may come from keratosis
squamous cell carcinoma
nevi moles light skin, sun burn history increase death rate early metastasis recurring
