Fig. 72-20

Pityriasis rosea: Pink ellipsoid papules are characteristic of the eruption.

Fig. 72-21

Pityriasis rosea: Elongated papules.


at072eg003.jpg

Fig. 72-22

Pityriasis rosea: A somewhat annular herald patch lateral to the sacrum and oval papules scattered on the back. The pigmented lesions are Clark’s nevi.


at072eg004.jpg

Fig. 72-23

Pityriasis rosea: The somewhat annular plaque is a herald patch that was joined by discrete papules and plaques which formed consequent to confluence of papules.


at072eg005.jpg

Fig. 72-24

Pityriasis rosea: Pink, elongated papules are aligned along lines of cleavage.


at072eg006.jpg

Fig. 72-25

Pityriasis rosea: There seem to be two herald patches, along with numerous red papules, some of the latter being aligned along lines of cleavage.


at072eg007.jpg

Fig. 72-26

Pityriasis rosea: Extensive involvement of the trunk by numerous collarettes of scale in company with dull-pink papules and plaques. At times the eruption may assume nearly erythrodermic proportion.

Pityriasis rosea: Scaly oval and round papules, some of the lesions being annular, in an African.
