An obstetrics fellow performed a circumcision using a Plastibell ® Circumcision Device on a healthy, term newborn male without incident several hours before discharge. The parents returned with the infant to the hospital emergency department because of a “bubble at the end of his penis the size of a grape.” The child was visibly distressed and crying, but this stopped when the “bubble” burst. An emergency medicine attending and a family medicine resident covering OB/GYN and pediatrics examined the newborn. Several diagnoses were entertained including an allergic reaction. Both physicians thought that the findings were not serious, and the child was discharged home with follow up the next day in the pediatric clinic.
