Psoriasis is characterized by well-demarcated erythematous papules and plaques with overlying scale. Scalp and face may be common sites in children.
Guttate psoriasis can follow a streptococcal infection; consider a throat and perianal swab for streptococci to assist in diagnosis and treatment.
Medium- to high-potency topical steroids with or without calcipotriol (Dovonex) or calcipotriene are first-line therapy.
Refer to dermatology specialist if persistent or widespread disease for consideration of systemic or light therapy.
