Picture of Psoriasis 3
This figure shows the erythema, scaling, and thickening of portions of the thumb and soles that are very common in both children and adults with psoriasis. Therapy of psoriasis is based on the skillful use, either alone or in combination, of a number of therapeutic agents. The most effective are topical steroids, tars, keratolytics, ultraviolet light, and topical calcipotriol and tazarotene in older patients. Children with simple plaque psoriasis can often be managed with short-contact anthralin preparations. When topical steroids are used, it is important to employ the least potent preparation that is effective and to avoid the use of fluorinated steroids on the face and in intertriginous areas. Finally, careful exposure to sunlight during the summer months and artificial ultraviolet light at other times is enormously beneficial in selected patients with extensive involvement.
