Pencil-tip injuries, although usually insignificant, have the potential to provoke granulomatous reactions. Other undesirable consequences of such injuries include pigmentation and abscess formation. Despite the rarity of such outcomes, it is important that clinicians are aware of the varying presentations of pencil-tip injury, as this can cause diagnostic uncertainty. Here, we present a case of graphite foreign body granuloma, originally thought to be a blue naevus-like localised argyria. The diagnostic work-up was complicated by the absence of a history of injury with a pencil-tip.
铅笔尖损伤虽然通常不太严重，但有可能引发肉芽肿反应。此类损伤的其他不良后果包括色素沉着和脓肿形成。尽管这些结果很罕见，但临床医生了解铅笔尖损伤的不同表现很重要，因为这可能导致诊断不确定性。在此，我们报告一例石墨异物肉芽肿病例，最初被认为是蓝痣样局限性银质沉着病。由于缺乏铅笔尖损伤史，诊断检查变得复杂。
