Comprehensive Coverage of ALL Dermatology Topics: Category Key Topics Covered Skin Cancers Basal cell carcinoma (most common skin cancer, pearly papules, cheeks/nose/face), squamous cell carcinoma (actinic keratosis precursor, chronic red scaly lesion, lips/ears/hands), melanoma (ABCDE – asymmetry, border, color, diameter 6mm, evolving; acral lentiginous melanoma in dark-skinned individuals),

papules/pustules/telangiectasias around nose/mouth – Metro gel, avoid triggers), seborrheic dermatitis (foam vehicle for hairline) Parasitic & Viral Skin Infections Scabies (interdigital webs, worse at night, never on scalp – permethrin 8-14 hours, treat everyone), pityriasis rosea (herald patch, Christmas tree pattern – self-limiting 4-6 weeks), molluscum contagiosum (white plug, dome-shaped with central umbilication – poxvirus, watchful waiting, cryotherapy), herpes zoster/shingles (unilateral dermatome, painful vesicles – antivirals within 72 hours), varicella/chickenpox (macules → papules → vesicles → crusts – supportive, acyclovir within 24 hours), herpetic whitlow (HSV on finger/thumb – self-limiting, acyclovir if recurrent), lichen planus (flat-topped purple bumps with Wickham's striae – topical steroids) Dermatologic Emergencies Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (target/bull's-eye rash, mucosal involvement, sloughing – SANA(p): Sulfonamides, Anticonvulsants, NSAIDs, Allopurinol, PCN), cellulitis with red streaks (lymphangitis – treat promptly), necrotizing fasciitis (surgical emergency), Rocky Mountain spotted fever (petechial rash on forearms/ankles/wrists spreading inward – doxycycline, fatal if not treated within 5 days), Brown recluse spider bite (painless bite, necrotic center, blisters – ice packs, treat like cellulitis), anthrax (papule → necrosis → ulceration – doxycycline, cipro, treat 60 days if bioterrorism) Ocular Disorders Blepharitis (bilateral red swollen eyelids, fine scales – scrub with warm water and baby shampoo), pterygium (surfer's eye – triangular white/yellow growth on nasal side, surgical removal), pinguecula (white/yellowish small round lesion – prevention with sunglasses), chalazion (small painless nodule – hot compresses), hordeolum/stye (painful red warm abscess – hot compresses, erythromycin if preseptal cellulitis), senile arcus (white-gray ring on cornea in elderly, check lipids if age 50), xanthelasma (soft yellow flat plaques – check fasting lipid profile), allergic conjunctivitis (bilateral itchy, stringy discharge – oral antihistamines, olopatadine drops), bacterial conjunctivitis (yellow-green crusting – topical fluoroquinolones), viral conjunctivitis (pink eye – supportive, highly contagious), herpes keratitis (fern-like lesion on fluorescein – ophthalmologist STAT), corneal abrasion (severe pain, foreign body sensation – erythromycin ointment, DO NOT PATCH), acute angle-closure glaucoma (severe eye pain, cloudy cornea, fixed mid-dilated pupil – ER STAT), papilledema (swollen optic disc due to increased ICP – ER), primary open-angle glaucoma (gradual peripheral vision loss – beta-blockers or prostaglandin drops, avoid beta-blockers in asthma/COPD), cataracts (night vision issues, glare, halos – red reflex test), age-related macular degeneration (painless central vision loss, straight lines appear curved – Amsler grid), retinal detachment (sudden floaters, flashes, curtain – ER STAT), dacryocystitis (lacrimal sac infection – massage + systemic antibiotics) ENT/Ear Disorders Meniere's disease (VAST – Vertigo, Aural fullness, Sensorineural hearing loss, Tinnitus – meclizine, antiemetics), acoustic neuroma (gradual unilateral sensorineural hearing loss, tinnitus, CN VIII – MRI, surgery), cholesteatoma (cauliflower, foul smell, hearing loss – SURGERY), Battle sign (bruising behind ear – basilar skull fracture – ER), BPPV (vertigo 1 minute with head movement – Dix-Hallpike, Epley maneuver), vestibular neuritis/labyrinthitis (sudden
