Primary vs Secondary Skin Lesion: Definition
Primary: Uncomplicated lzn representing initial pathologic change, uninfluenced by secondary alterations such as infection, trauma, or therapy

Secondary: lesion in which a change has occurred as consequence of progression of disease
List and define categories of skin lesions (macule, vesicle, etc)
Macule: flat, <1cm
Patch: Macule >1cm

Papule: solid, raised lesion, <1cm
Plaque: papule >1cm

Vesicle: lesion <1cm filled with clear fluid
Bulla; Fluid-filled lesion >1cm in diameter
Where does psoriasis appear?
Extensor surfaces
Where does atopic eczema appear?
Flexor surfaces
Behind ears
What does it mean when a lesion is an iris lesion?
Annular lesion with a second ring "bull's eye"
Annual skin cancer screening if a category ___ recommendation.
Category I
What lesion diameter is a risk for malignancy?
6mm+
What DRE findings raise suspicion for malignancy?
Prostate firm, nodular, asymmetric, or indurated

(BPH = symmetrically firm and enlarged)
What is the most common form of skin cancer?
Basal Cell Carcinom
Basal Cell Carcinoma vs Squamous Cell Carcinoma:
Appearance
Basal: plaque-like with waxy, translucent appearance, often with ulceration and telangiectasia. No itching or change in skin color.

SCC: Scaly, pink macular to papular area with erythematous RAISED BASE. Sometimes scale or ulcerated. Borders often irregular and bleed easily. UNLIKE BASAL CELL, heaped-up edges of lesions are FLESHY rather than CLEAR in appearance.
When is shave biopsy indicated?
When lesion is elevated above surface of skin
Under what circumstances should PSA be obtained in setting of BPH?
If life expectancy > 10 years
If PSA level will influence BPH treatment (e.g., patient considering treatment with 5-alpha reductase inhibitor)
What is the most widely used treatment for cutaneous squamous cell carcinoma?
Surgical Incision
When is Mohs microscopic surgery indicated?
Patients with any non-melanoma skin cancer greater than 2 cms, lesions with indistinct margins, and those close to important structures (eyes, nose, mouth)
When is topical 5-FU indicated?
SUperficial SCCs and SCC in situ
What is the downfall to cryotherapy?
Does not permit histologic confirmation of adequacy of treatment margins.

Useful for small, well-defined, low-risk, invasive SCCs and Bowen's dz.
BPH:
Medical Management
Medical: alpha-antagonists (tamsuolosin, terazosin) decrease syx of LUTS

5-alpha-reductase inhibitors (finasteride) more effective in men w/larger prostates

If severe enough, combine above classes

Sx:
If bladder outlet obstruction creating risk for UTI or lower UTI, consider surgery
Tinea capitis:
Treatment
ORAL THERAPY (topical tx unable to penetrate hair shaft)

Griseofulvin
Tinea unguium:
Treatment
Terbinafine 250 mg qd x 12 weeks for toenails, 6 weeks for fingernails
How does the composition of a cream differ from an ointment? Lotion?
Cream: organic chemicals (oils) and water; can be used in any area, drying effect with continuous use

Ointments: Limited organic compounds consisting of grease (petroleum jelly), with little or no water; desirable for dryer skin. Greater penetration than cream and thus enhanced potency

Lotions/gels: Contain EtOH; most useful in scalp because penetreate easily, leave little residue. Drying effect.
What are the strongest steroid creams?
Weakest?
Strongest: Betamethasone, Halobetasol

Weakest: Hydrocortisone
What are the side effects of steroid creams?
Skin atrophy (most common)
Hypopigmentation (more apparent with darker skin tones)
HPA suppression...
Where are fractures likely to occur in those with osteoporosis?

Which fractures carries the greatest mortality?
Vertebrae
Hip
Distal radius
Proximal humerus

Hip fracture has mortality rate of 20-25%
What are the risk factors of osteoporosis?
Previous fragility fracture (low impact)
Smoking
Heavy EtOH
Corticosteroid use
Caucasian race
Lower body weight
What is the FRAX tool?
Tool developed by WHO to calculate risk of fractures; adjusts for gender, ethnicity, and locale
How would you interpret the T scores provided on a DEXA scan?
0 to -1: Normal
-1 to -2.5: Decreased bone density, or osteopenia
Less than -2.5: Osteoporosis

Note T = standard deviation of average peak bone mass density in a young healthy person
What are the USPSTF guidelines for breast cancer screening?
Mammogram every 2 years for 50-74

If wish to initiate prior to 50, should be individualized decision
What are the ACOD guidelines for Pap smears?
Every 2 years from 21-30
Every 3 years from 30-64
Is CA-125 level indicated as a screening tool for ovarian cancer?
No
What are the risk factors for endometrial cancer?
Any inc'd exposure to unopposed estrogen:
Unopposed estrogen therapy
Tamoxifen
Obesity
Anovulatory cycles
Estrogen-secreting neoplasms
Early menarche (before 12)
Late menopause (after 52)
Nulliparity

Other factors include:
-HTN
-DM
-Hx breast or colon ca
-Menstrual irregularities
-Age
What cancer is smoking protective against?
Endometrial
What factors are protective against endometrial cancer?
Smoking (decreases estrogen exposure)
Oral Contraceptive Use (increases progestin levels, thus providing protection)
What is the differential for abnormal uterine bleeding in a postmenopausal woman?
Cervical polyps (common in postpartum and perimenopausal women; r/o via pelvic exam)

Endometrial hyperplasia (progresses to cancer in <5% pts)

Endometrial cancer (90% pts with Endometrial Ca have abnl vaginal bleeding)

Proliferative Endometrium: seen in high estrogen states

Iatrogenic causes: anticoags, SSRIs, antipsychotics, steroids, hormones

Genital Tract Pathology
What tests/labs should be ordered in a postmenopausal woman with abnormal vaginal bleeding?
Transvaginal Ultrasound: most cost-effective test if low risk for endometrial cancer; highly sensitive for detection of endometrial cancer and abnlty

Endometrial biopsy: Gold standard for evaluation of pt with high risk for endometrial cancer. Widely done in outpt setting.

CBC, LFTs: anemia, low PLT, liver abnlts

Thyroid Function Tests: can interfere with HP/Gonadal axis

FSH, LH; Elevated FSH confirms menopause (less inhibin around), elevated LH too
How can osteoporosis be prevented?
Adults 50 and over should consume 800 IU vitamin D daily
Most adults should consume 1000mg calcium, if over 50, consume 1200 mg

Life-long weight-bearing exercise and muscle strengthening (walking, jogging, Tai-Chi, stair climbing, dancing, tennis)

Limit smoking and excess EtOH
What is the treatment of osteoporosis?
Bisphosphanates: inhibit bone resorption and reduce bone turnover, increas ebone mineral density. Ex: ALENDRONATE

Parathyroid hormone: Forteo; only if high risk for fracture, given SQ, $$$

Estrogen Replacement Tx: short-term only

Calcitonin: reduces vertebral fractures, but not hip or other fractures
What is the benefit of menopause hormone therapy? Concerns?
Use for short-term relief of bothersome syx of menopause; improves vasomotor and atrophic symptoms, prevents osteoporosis

Concerns: If given for more than 3 years, risk of breast cancer; unopposed estrogen risks endometrial cancer; beginning after age 60 increases risk of CAD; inc'd risk of stroke after first 1-2 years of use

Use lowest effective dose for shortest possible time
