Unusual sequela from a pencil stab wound reveals a retained graphite foreign body.

Penetrating pencil-tip injuries are common among children and usually resolve without long-term sequelae. However, failure to detect and remove embedded pencil fragments can result in increased morbidity or misdiagnoses of other, more serious, conditions. We report on the case of a 10-year-old boy stabbed with a pencil on his right chin. Initial treatment in the emergency department included irrigation and closure of the laceration. Following suture removal, the patient returned to the emergency department (with bright-purple drainage from the wound site). Radiographic evaluation led to the discovery of an embedded foreign body requiring surgical removal.
