“Dermatology 101”
If it’s dry: WET it
If it’s wet: DRY it
If it’s red and itchy: Use steroids
MORE COMPLEX!!
Medicine is a calling, not a business.
You are in this profession as a calling, not as a business; as a calling which exacts from
you at every turn self-sacrifice, devotion, love and tenderness to your fellow-men. Once
you get down to a purely business level, your influence is gone and the true light of your
life is dimmed. You must work in the missionary spirit, with a breadth of charity that
raises you far above the petty jealousies of life.
Sir William Osler
Clinical pearls
Dry skin
Topical corticosteroids

Worsens almost any skin condition
Seasonal
Moisturizers
Tips
Types
Avoid long, hot showers
Towel dry (get big drops off)
Apply to damp skin
Ointment > cream > lotion

Topical Corticosteroids
Treat the erythema, not the itch

Incidence
Lifetime risk (2006)
1930: 1 in 1500
1960: 1 in 600
2001: 1 in 71
Caucasians: 1 in 60 (slightly higher in males)
Non-caucasians: 1 in 1176
75% of skin cancer deaths
Melanoma
4 main types of malignant melanoma
Clinical prediction rules
ABCDE criteria (ACS)
7 point checklist (UK)
Types of melanomas
Superficial spreading
50% of cases
More frequent in
younger adults
Types of melanomas
Nodular
20 to 25% of cases
Also in younger adults
Types of melanomas
Lentigo maligna
15% of cases
Older adults
Types of melanomas
Acral-lentiginous
10% of cases
Palms, soles, around first
toenail
Risk factors for malignant
melanoma
Atypical nevus syndrome with personal and
family hx of melanoma (500)
Changing mole (>400)
Atypical nevus syndrome with family hx of
melanoma (148)
Age > 15
Dysplastic moles (7-70)
Risk factors con’t
Large congenital nevus (> 15 cm) (17)
Caucasian race (12)
Atypical nevi (7-27)
Regular tanning bed use before age 30 (7.7)
Multiple nevi (5-12)
Personal hx of melanoma (5-9)
Family hx (first degree) of melanoma (3-8)
Sun sensitivity/tendency to burn (2-3)
Clinical prediction rules
ABCDE Criteria (American Cancer Society)
7 point checklist (United Kingdom)
ABCDE Criteria
Asymmetry
Border
Color
Diameter
Evolving (Elevation or Enlargement)
Asymmetry
Border
Color
Diameter
Evolving (elevation/enlargement)
7 point checklist (Glasgow)
Major signs (1 or more):
Minor signs:
Change in size
Inflammation
Change in shape
Crusting or bleeding
Change in color
Sensory change
Diameter > 7 mm
A2BCD3EFG’s of Melanoma
2005 Additions:
Angularity
Dysplastic
Different (from patient’s other nevi)
EVOLVING
Family history
Great numbers of nevi
Clinical Assessment
Apply the ABCD+ criteria
Excisional (full thickness) biopsy if either test
has positive criteria or if you or your patient
has any doubt
Guidelines are developed from large studies
and tell you nothing about the patient in front
of you
The Bottom Line Re: Melanomas
When educating patients, if one were to stress
only one characteristic of melanoma, it would
be CHANGE.
However, only 25% of melanomas arise from a
preexisting lesion. 75% of the time they arise
de novo!
CA-MRSA
Acquisition
Treatment
Contact, skin breakdown, hygiene
Physician-directed medication, drainage, care
Prevention
Wash hands often, use alcohol-based hand rubs
Keep cuts/scrapes clean and covered
Do not touch other people’s cuts or bandages
Do not share personal items, such as towels or razors
Diagnostic Tools
Experienced clinician/proper environment
KOH
Culture
Biopsy
Bacterial (+/- sensitivity)
Viral
Fungal
Punch
Specialty referral is not needed in most cases
Live neither in the past nor in the future,
but let each day’s work absorb your
entire energies, and satisfy your widest
ambition
