Transient swelling of the costochondral and sternal region in infants.

ABSTRACT

Four children aged 9 months, 11 months, 1 year, and 1 year 4 months, respectively, presented to the emergency room with an acute tender swelling of the sternum or sternocostal cartilage. Three of these resolved spontaneously within a few weeks of presentation, and in one curettage was carried out. We were unable to find any other references in the literature of this condition occurring in infants. Acute swelling of the chest wall frequently is due to neoplastic or infectious disease, and culture of aspirated material and possibly biopsy has been recommended in all cases. Our experience suggests that this may not always be necessary.
