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.

Zwitterionic Polymer

The superhydrophilic and ultralow biofouling properties as well as the resistance to foreign-body reaction make zwitterionic polymer promising in biomedical applications.

Inflammatory Changes

A young dog was presented to the veterinary ophthalmology service with marked unilateral anterior uveitis and blindness, extreme pain, anorexia and weight loss. Porcupine quill migration into the orbital and ocular tissues was suspected due to an encounter with a porcupine three weeks previously. Surgical orbital extenteration and exploration revealed two porcupine quill segments penetrating the oculus bulbi and extending into the orbital tissues. The location and movement of the quills within the globe and orbital muscle cone during mastication accounted for the deep pain, anorexia and weight loss. The quills incited a sterile foreign body reaction with fibroplasia and granulation tissue formation in the sclera and ciliary body. The eye was avisual due to the anterior segment structural and inflammatory changes.

Pencil Lead

Pencil core granuloma is characterized by a delayed foreign-body reaction against retained fragments of pencil lead. Previous case reports presented pencil core granuloma resembling malignant melanoma, haemangioma, or soft tissue sarcoma. We present a case of pencil core granuloma arising from the palm 25 years after the initial injury. The patient presented a bluish nodule that had been present over 25 years before. The nodule initially measured 5 mm in diameter. However, five years before presentation, it suddenly enlarged to the size of 30 mm during six months. Computed tomography (CT) of the lesion revealed a linear radiopaque structure of 8 mm long with a mass on its distal end. Surgical resection revealed a bluish muddy mass and pencil lead. Histological examination revealed degenerative tissue with calcification surrounded by massive amounts of black granular material in the middle and lower dermis.
