title: Fifty-Three Years after a Pencil Puncture Wound.
abstract: A pencil core with an intact pencil tip was excised from the thigh of a 60-year-old male 53 years after a puncture wound. Histologic examination of the excised pencil core and the surrounding tissue revealed a foreign body reaction with abundant entrapped dark black pigment and chronic reparative changes, including dense sclerosis and focal granulation tissue formation.
