Graphite Foreign Body of the Conjunctiva Simulating Melanoma

Orbital foreign body masquerading as conjunctival melanoma 60 years after injury

“…In our case, the appearance of the pigmented lesion 60 years after the initial trauma raised concerns for an acquired melanoma. Conjunctival melanomas are potentially lethal neoplasms often arising from de nova , nevi or primary acquired melanosis on the conjunctiva and previous reports have described occult foreign bodies simulating a choroidal and conjunctival melanoma 3,4 . Although the pigmented lesion appeared suspicious for a conjunctival melanoma, it represented a retained orbital foreign body that surfaced many years after the initial orbital trauma.…”

A Worrisome Subcutaneous Tumor on the Forehead of a Young Woman

“…[1][2][3][4][5][6][7][8] The diagnosis may not be suspected clinically and be a surprise on the histology results because the initial trauma has been totally forgotten by the patient. However, persistence of foreign material in the dermis may lead to the development of a delayed foreign body reaction against retained fragments of pencil lead (PCG, also called pencil lead granuloma or graphite granuloma).…”

A Case of Graphite Foreign Body Misdiagnosed as Blue Nevus

“…However, several reports indicate that stab injuries caused by pencils can result in undesirable reactions, such as pigmentation, abscess formation, and soft tissue reaction [1][2][3][4][5] . There are only a few previous case reports in literature of pencil core granuloma presenting to dermatologists, plastic surgeons, ophthalmologists, and neurosurgeons as a suspected melanoma, soft tissue sarcoma, hemangioma or abscess [1][2][3][4][5][6][7][8][9][10] . Here we report a 19-year-old woman with a foreign body, the lead of a pencil, misdiagnosed as a blue nevus.…”
