Pyogenic granulomas are benign lesions commonly found on the skin and mucosal surfaces. Although the etiology of pyogenic granuloma is not well understood, some reports have suggested that PG may be caused by impaired wound healing following tissue injury. Rare cases of pyogenic granulomas in the setting of local foreign body have been reported in the literature. Although foreign body reactions have not been identified as a cause of pyogenic granuloma, these reports evidence the need to further investigate this association. We present a 33-year-old man who presented with a pyogenic granuloma on the scalp six years after a contralateral skull-penetrating gunshot wound that resulted in retained bullet fragments.
化脓性肉芽肿是一种常见于皮肤和黏膜表面的良性病变。虽然化脓性肉芽肿的病因尚不清楚，但有一些报道表明 PG 可能是由于组织损伤后伤口愈合受损引起的。文献中有少数化脓性肉芽肿在局部异物的情况下的报道。虽然异物反应尚未被确定为化脓性肉芽肿的原因，但这些报告表明需要进一步研究这种关联。我们报告了一名 33 岁男性的病例，他在对侧颅骨穿透性枪伤后六年出现头皮化脓性肉芽肿，导致遗留弹片。
