Localized gingival lesions in young febrile, irritable infants have recently been described, often in association with occult pneumococcal bacteremia. A review of the literature discloses eight such reported cases, many of which had concomitant ipsilateral buccal cellulitis.1-3 This constellation of symptoms has been so typical that Yeager3 suggested the presence of a cystic gingival lesion in a febrile infant with leukocytosis (1) should alert the clinician to the distinct possibility of concomitant pneumococcal bacteremia and (2) seems to be pathognomonic for this bacteremia. Recently, we cared for a febrile infant who had a cystic gingival lesion, mimicking a hemorrhagic preeruption dentigerous cyst, from which a pure growth of group A β-hemolytic streptococcus was obtained. The purpose of this report is to alert the pediatrician to the entity of a pyogenic gingival cyst of infancy and to stress the importance of aggressive diagnosis and antimicrobial therapy. We emphasize the
