title: Neutrophilic figurate erythema of infancy.
abstract: We describe a transient figurate erythema in an 11-month-old female infant with a 2-month history of arcuate and annular erythematous lesions localized on the face, trunk, and limbs. Constitutional symptoms were absent. Previous medical history was unremarkable. Full blood examination, erythrocyte sedimentation rate, antistreptolysin-O titer, anti-Ro, and anti-La antibodies were within normal limits or negative. Histologic examination revealed a superficial and deep perivascular and interstitial dermatitis constituted mostly of neutrophils and abundant nuclear dust. The lesions resolved spontaneously within a few months without scarring or atrophy. Recurrence has not occurred. This case suggests that figurate erythemas in infants rarely may disclose a neutrophilic histologic pattern, which must be differentiated from that of other neutrophilic dermatoses.
