Abstract

Pencil core granulomas are still infrequently reported in the literature. A 67-year-old woman presented with a 4mm hard blue subcutaneous nodule on the forehead. She remembered being injured with a pencil tip about 60 years before. The subcutaneous nodule was excised, which microscopically revealed a foreign body reaction with histiocytes containing fragmented coarse black particles. We diagnosed pencil-core granuloma based on the patient's history of pencil tip injury and histological examination findings.

摘要

铅笔芯肉芽肿在文献中仍鲜有报道。一名67岁女性前额出现一个4毫米的坚硬蓝色皮下结节。她记得大约60年前曾被铅笔尖刺伤。切除该皮下结节，显微镜检查显示有异物反应，组织细胞内含有破碎的粗大黑色颗粒。根据患者铅笔尖损伤史及组织学检查结果，我们诊断为铅笔芯肉芽肿。
