A recent update published in Journal of the American Academy of Dermatology stated the Joint American Academy of Dermatology-National Psoriasis Foundation Guidelines of care for the management and treatment of psoriasis in pediatric patients. The recommendations suggested that:

• Topical corticosteroids can be used for the treatment of pediatric psoriasis—as an off-label therapy.
• Calcipotriene/calcipotriol is recommended as a treatment option for childhood plaque psoriasis; monitoring of vitamin D metabolites may be considered during calcipotriene/calcipotriol therapy when applied to a large body surface area.
• The combination of calcipotriol/betamethasone dipropionate ointment applied once daily for up to 4 weeks at a time, is a safe and effective treatment modality for children aged 12 years and older, with mild to moderate plaque psoriasis.
• The combination of calcipotriol/betamethasone dipropionate suspension applied once daily for up to 8 weeks at a time, is a safe and effective treatment option for children aged 12 years and older, with mild to moderate plaque psoriasis of the scalp.
• The use of coal tar preparations in conjunction with phototherapy is effective for the treatment of psoriasis in children but may be limited by the theoretical long-term risk of carcinogenesis.
• Methotrexate is recommended as an effective systemic therapy for moderate to severe plaque psoriasis and other psoriasis subtypes in children.
• Folic acid supplementation daily or 6 times weekly during treatment with methotrexate is recommended; routine clinical and laboratory monitoring is recommended before and during treatment with methotrexate.
