Distinguished by its characteristic annular or 'sunflower-like' arrangement of pustules and confirmation with direct immunofluorescence, unlike the sheet-like erythema of the others.
Identified by the presence of classic honey-colored crusts and a positive bacterial culture, distinguishing it from the sterile pustules of the other conditions.
Suspect this in a patient with a known history of psoriasis, often presenting with more widespread, confluent 'lakes' of pus and systemic symptoms like fever.
Characterized by chronic, relapsing crops of flaccid pustules primarily in the flexures that lack the fever and acute onset of AGEP or pustular psoriasis.
