Individual Lesions

at008g14.jpg

Fig. 8-14

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


at008g15.jpg

Fig. 8-15

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


at008g16.jpg

Fig. 8-16

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


at008g17.jpg

Fig. 8-17

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


at008g18.jpg

Fig. 8-18

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


at008g19.jpg

Fig. 8-19

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


at008g20.jpg

Fig. 8-20

Lichenification covered by scales and associated with erosions and ulcerations.


at008g21.jpg

Fig. 8-21

Lichenification surmounted by scales and traversed by fissures.


at008g22.jpg

Fig. 8-22

Erythematous scaly plaques with indistinct borders.


at008g23.jpg

Fig. 8-23

Reticulated hyperpigmentation and lichenification (“dirtyneck”).


at008g24.jpg

Fig. 8-24

Hyperpigmentation and lichenification.


at008g25.jpg

Fig. 8-25

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


at008g26.jpg

Fig. 8-26

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


at008g27.jpg

Fig. 8-27

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


at008g28.jpg

Fig. 8-28

Shiny nails result from buffing them by longstanding intense rubbing.


at008g29.jpg

Fig. 8-29

Accentuation of palmar creases (hyperlinearity of palms).


at008g30.jpg

Fig. 8-30

Lichenification of the scrotum.


at008g31.jpg

Fig. 8-31

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


at008g32.jpg

Fig. 8-32

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


at008g33.jpg

Fig. 8-33

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


at008g34.jpg

Fig. 8-34

Hypopigmented scaly patches of pityriasis alba in an atopic child.


at008g35.jpg

Fig. 8-35

Monomorphous nonkeratotic follicular papules.
