Pediatric Dermatology Cheatsheet

Key Concept: Distinguish conditions by skinfold involvement and satellite lesions (candidal vs irritant), proliferating vs flat vascular lesion (hemangioma vs port-wine stain), and distribution by age (atopic: face/extensors in infants, flexors in older children).

Diagnosis	Key Features
Infantile Hemangioma	Bright red, raised plaque appearing days-weeks after birth Proliferates age 0-12 mo; involutes after age 1-5 yr Periorbital → visual impairment risk (amblyopia) Facial/segmental → PHACE workup Beard distribution → laryngoscopy High-risk: oral propranolol (vasoconstriction → regression) Pulsed dye laser = port-wine stains (NOT hemangiomas)
Irritant Diaper Dermatitis	Erythema confined to diaper contact area Spares skin folds No satellite lesions Caused by moisture + friction First-line: barrier ointment (petrolatum/zinc oxide)
Candidal Diaper Dermatitis	Beefy-red, confluent plaques Involves skin folds Satellite lesions present Risk: recent antibiotics, prior thrush Treatment: topical nystatin
Atopic Dermatitis	Face, trunk, extensor surfaces (infants) Flexural creases (older children/adults) Diaper area classically spared Filaggrin mutation → skin barrier dysfunction Topical emollients + topical corticosteroids Eczema herpeticum: HSV superinfection
