ABSTRACT
@#Annular pustular psoriasis (APP) is a rare variant of pustular psoriasis occurring only in about 1-5.4% of children with psoriasis. Pustular psoriasis is triggered by endogenous and exogenous factors. Exogenous factors include stress, upper respiratory tract infection and withdrawal of systemic corticosteroids. This condition usually requires systemic treatment. However, there are still no randomized controlled trials or standardized guidelines proving the advantage of any specific treatment modality over the other. We report a case of a 6-year-old male who presented with diarrhea followed by appearance of erythematous annular plaques with pustules and nail changes. Punch biopsy showed pustular psoriasis. Patient was treated with topical betamethasone valerate and calcipotriol, and there was noted to have no recurrence of skin lesions for 4 months.
