Nodular presentation of eosinophilic cellulitis (Wells' syndrome).

Eosinophilic cellulitis is a rare condition of unknown aetiology. The classical presentation is of a tender or mildly pruritic cellulitis-like eruption, that has typical histology characterized by tissue eosinophilia, oedema and "flame" figures. Other reported clinical presentations include papular and nodular eruptions. It may be recurrent, and preceded at a variable time by a pruritic papular eruption. We describe a patient with the rare nodular variant of eosinophilic cellulitis affecting the palms of the hands, which occurred 2 years after a nonspecific pruritic papular eruption, without an obvious precipitant and in the absence of the more typical cellulitis-like plaques.
