Atopic Dermatitis and Its Analogues (lichen simplex chronicus, prurigo nodularis, picker’s nodules, and erosions and ulcerations secondary to excoriation) | Chondrodermatitis Nodularis Helicis
Scale-crusts interrupted by fissures on cheeks (“eczemacraquelé”) and yellow crusts on scalp (“crusta lactea”).
Erythematous scaly plaques. The paranasal folds are largely spared because they are indented.
Erosions and hemorrhagic crusts atop lichenified plaques. Signs of scratching are the excoriations.
Erythroderma, erosions covered by hemorrhagic crusts, and lichenification in an obviously atopic person.
Lichenification and fissures at the angles of the mouth and lichenification of the upper lip.
Dusky erythema, lichenification, and scales on wrinkled skin (juvenile plantar dermatosis). Arches are spared.
Linear zones of pallor after a recent scratch of erythematous skin (“white dermographism”).
“White dermographism” induced artifactually by strokes of a blunt-tipped object against erythematous skin.
