Targetoid spongiotic reaction pattern: A case series of seven paediatric patients

We present seven cases of a targetoid eruption, clinically mimicking erythema multiforme, occurring in paediatric patients aged 12 months to 14 years. All patients presented with a pruritic targetoid eruption on body and acral sites which spared mucosal areas. All patients demonstrated a spongiotic reaction pattern on histology without lichenoid change and demonstrated excellent responses to either oral prednisolone or topical corticosteroids. We propose the term 'targetoid spongiotic reaction pattern (TSRP)' for our subset of paediatric patients. We review the literature regarding targetoid eruptions in the paediatric population.
