Annular pustular psoriasis is a unique variant of pustular psoriasis with a relatively good prognosis. It has been classified in four forms: von zumbusch, annular, exanthematous and localized (except for palmoplantar). The APP variant has also been referred to as “erythema circine recidivants”, Lapiere-type psoriasis, and erythema annulare centrifugum-type psoriasis.
Five year old male child came with pus filled lesions over the body since 1 month. He had similar complaints 7 months back which were pus filled lesions. He presented with fever associated with chills. Lesions were in form of well-defined annular erythematous plaques surrounded by a rim of few mm size pustules present over trunk and extremities both in extensor and flexor area. Histopathological examination showed sub corneal pustule, club shaped rete ridges and suprapapillary thinning with dilated blood vessels. A diagnosis of annular pustular psoriasis was made.
We report this case for the rarity of the condition with chronic and relapsing course but with a good prognosis.
