Embedded cactus spines may cause immediate pain due to mechanical damage, be a source of infection, or result in foreign body granulomas. The cholla cacti are particularly tenacious in the manner in which the spines stay embedded in the skin. Pulling away from the cactus may result in a portion breaking away from the main plant and embedding other spines. Granuloma formation has been seen with plant material embedded in the dermis. Onset is generally within a few days, and duration may be as long as 9 mo. Treatment is generally best accomplished with a topical corticosteroid. We present a case of granuloma caused by the cactus Opuntia acanthocarpa which persisted for 8 w despite topical treatment with 0.05% fluocinonide.
嵌入的仙人掌刺可能因机械损伤而立即引起疼痛，成为感染源，或导致异物肉芽肿。刺梨仙人掌的刺嵌入皮肤的方式特别顽固。从仙人掌上拉扯可能会导致一部分刺从主体植物上断裂并嵌入其他刺。在真皮中嵌入植物材料时可见肉芽肿形成。通常在几天内发病，持续时间可能长达9个月。一般用外用皮质类固醇治疗效果最佳。我们报告一例由仙人掌Opuntia acanthocarpa引起的肉芽肿病例，尽管外用0.05%氟轻松治疗，但仍持续了8周。
