Atopic Dermatitis and Its Analogues (lichen simplex chronicus, prurigo nodularis, picker’s nodules, and erosions and ulcerations secondary to excoriation) | Chondrodermatitis Nodularis Helicis

Individual Lesions

Fig. 8-14

Scale-crusts interrupted by fissures on cheeks (“eczemacraquelé”) and yellow crusts on scalp (“crusta lactea”).


Fig. 8-15

Excoriations covered by crusts in company with lichenification, erythema, and scaling.


Fig. 8-16

Erythematous scaly plaques. The paranasal folds are largely spared because they are indented.


Fig. 8-17

Erosions and hemorrhagic crusts atop lichenified plaques. Signs of scratching are the excoriations.


Fig. 8-18

Erythroderma, erosions covered by hemorrhagic crusts, and lichenification in an obviously atopic person.


Fig. 8-19

Diffuse erythema traversed by linear excoriations and covered by subtle scale-crusts.


Fig. 8-20

Lichenification covered by scales and associated with erosions and ulcerations.


Fig. 8-21

Lichenification surmounted by scales and traversed by fissures.


Fig. 8-22

Erythematous scaly plaques with indistinct borders.


Fig. 8-23

Reticulated hyperpigmentation and lichenification (“dirtyneck”).


Fig. 8-24

Hyperpigmentation and lichenification.


Fig. 8-25

Lichenification and fissures at the angles of the mouth and lichenification of the upper lip.


Fig. 8-26

Erythema, scales, and a fissure of the tip of a toe whose nail is dystrophic.


Fig. 8-27

Dusky erythema, lichenification, and scales on wrinkled skin (juvenile plantar dermatosis). Arches are spared.


Fig. 8-28

Shiny nails result from buffing them by longstanding intense rubbing.


Fig. 8-29

Accentuation of palmar creases (hyperlinearity of palms).


Fig. 8-30

Lichenification of the scrotum.


Fig. 8-31

Linear zones of pallor after a recent scratch of erythematous skin (“white dermographism”).


Fig. 8-32

“White dermographism” induced artifactually by strokes of a blunt-tipped object against erythematous skin.


Fig. 8-33

Hypopigmented scaly patches in an atopic child (“pityriasis alba”).


Fig. 8-34

Hypopigmented scaly patches of pityriasis alba in an atopic child.


Fig. 8-35

Monomorphous nonkeratotic follicular papules.
