Annular pustules in Kawasaki disease: a further case indicating the association with psoriasis?

We report the case of a 4-year-old girl with Kawasaki disease (KD), or mucocutaneous lymph node syndrome, who presented with an annular pustular eruption. Targetlike erythematous and scaly patches were observed after resolution of the pustules. A biopsy of the skin was performed, and results showed spongy pustules not associated with the intraepidermal eccrine duct. Generalized pustular eruption, including pustular psoriatic lesions, has been described in KD. However, to our knowledge, this is the first report of annular pustular eruption mimicking annular pustular psoriasis in KD.
