Impetigo
superficial skin infection, honey crusting, highly contagious
SA, GAS
Dermatitis
a group of inflammatory pruritic skin disorders; allergy (IV HS), chemical injury of infection
Atopic dermatitis (eczema)
pruritic eruption, commonly on flexor surfaces, often associated with other atopic disease (asthma, allergic rhinitis)
Allergic contact dermatitis
type IV HS reaction that follows exposure to allergen (poison ivy, poison oak, nickel, rubber, chemicals)
lesions occur at site of contact
psoriasis
epidermal hyperplasia (acanthosis) with parakeratotic scaling (nuclei still stratum corneum), esp on knees on elbows
increased stratum spinosum, decreased stratum granulosum; aspitz sigh
silvery scale
Dermatitis herpetiformis
pruritic papules and vesicles; deposits of IgA at tips of dermal papillae. Associated with celiac disease
lichen planus
pruritic, purple, polygonal papules; infiltrate of lymphocytes at dermoepidermal junction.
Steven Johnson syndrome
caused by sulfa and anticonvulsant drugs- major form of erythema multiforme. Characterized by high fever, bulla formation, and necrosis, ulceration of skin and high mortality rate
Erythema multiforme
Associated with infections, drugs, cancers and AI disease. Presents with multiple types of lesions, including macules, papules and vesicles and target lesions (red papules with a pale central area)
seborrheic keratosis
flat, pigmented squamous epithelial proliferation with keratin-filled cysts (horn cysts) benign
actinic keratosis
caused by sun expsoure; small rough erythematous or brown papules. Premalignant lesion. Risk of carcinoma is proportional to epithelial dysplasia
keloid
tumor of connective tissue elements of dermis that causes raised, thickened scars. Follows trauma to skin, especially in AA
tx: intralesional steroids to thin the skin
Bullous pemphigoid
AI disorder with IgG antibody against epidermal basement membrane hemidesmosomes (linear IF). Similar to but less severe than pemphigous vulgaris- affects skin but spares oral mucosa
Pemphigus vulgaris
potental fatal AI skin disorder. Intraepidermal bullae involving oral mucosa and skin. Findings: acatholysis (breakdown of epithelial cell to cell junctions), IgG antibody against epidermal cell surface desmosomes (IF throughout epidermis)
Verrucae (warts)
soft tan colored cauliflower like lesions. epidermal hyperplasia, hyperkeratosis, kiolocytes
verruca vulgaris on hands, condyloma acuminatum on gentials
sq cell carcinoma
very common; associated with excessive sun exps and arsenic. commonly appear on hands and face. locally invasive but rare mets. see keratin pearls
precusor: actinic keratosis
basal cell carcinoma
most common in sun exps areas. locally invasive but rare mets. see pearly papules
shiny dome
telangiectasias, palisading nuclei
melanoma
common tumor with significant risk of mets; associated with sunlight expsoure; fair skinned persons at increased risk. incidence high. depth of tumor correlates with risk of mets
acne
hyperkeratosis, sebum overproduction, proprionibacterium acnes proliferation, inflammation
tx: topical vit A, estrogens, steroids, isotrenitoin (accutane), benzoyl peroxide, topical/oral AB
