The authors present a case of a gradually enlarging pigmented mass of the upper eyelid and anterior orbit that was discovered to be the graphite tip of a pencil surrounded by macrophages bearing graphite and fibrous tissue. A 25-year-old woman with no medical history presented with a gradually enlarging pigmented lesion of her left upper eyelid. She denied any history of previous skin cancer, trauma, or previous surgery. A biopsy was performed. This revealed an encapsulated grayish, pigmented mass within the medial portion of the left upper eyelid and anterior orbit. Within the pigmented cocoon, the graphite core of a pencil ("pencil lead") was identified. Histopathology demonstrated granulomatous inflammation with fibrosis and macrophages.
作者报告了一例上睑和眶前部逐渐增大的色素性肿物病例，该肿物被发现是铅笔的石墨芯，周围有含石墨的巨噬细胞和纤维组织。一名无病史的25岁女性因左上睑逐渐增大的色素性病变就诊。她否认既往有皮肤癌、外伤或手术史。进行了活检。结果显示左上睑内侧和眶前部有一个包膜完整的灰白色色素性肿物。在色素性包囊中，发现了铅笔的石墨芯（“铅笔芯”）。组织病理学显示伴有纤维化的肉芽肿性炎症及巨噬细胞。
