Pyogenic granuloma (PG) is a common benign vascular proliferation which often occurs on the head, neck, hands, and feet. Among the various treatment options for PG, surgical excision is the most effective treatment which offers the lowest overall recurrence rates and also provides the exact diagnosis. However, it could have difficulties to do the surgery when lesions are located on the fingers and toes, especially very near to the nails, so laser may be a very good alternative choice. In this article, we evaluated the clinical efficacy and safety of neodymium-yttrium aluminum garnet (Nd:YAG) laser for treatment of PG located on the fingers and toes. Twenty-one patients with 21 PGs located on the fingers and toes were treated by multispot Nd-YAG laser. We chose monopulse (pulse width 10.5-13.5 ms; energy 100-125 J/cm); treatment interval was 3-4 weeks. All lesions disappeared after one or two treatments. There was no apparent scar formation, no impact on the function of the fingers and toes, no damage to nail growth, and no recurrence in more than 12-month follow-up. Nd-YAG is an effective and safety treatment option for treatment of PG located on the fingers and toes.
化脓性肉芽肿（PG）是一种常见的良性血管增生，常发生于头、颈、手和足部。在PG的各种治疗选择中，手术切除是最有效的治疗方法，其总体复发率最低，还能提供确切的诊断。然而，当病变位于手指和脚趾，尤其是非常靠近指甲的部位时，手术可能会有困难，因此激光可能是一个很好的替代选择。在本文中，我们评估了钕钇铝石榴石（Nd:YAG）激光治疗位于手指和脚趾的PG的临床疗效和安全性。21例手指和脚趾患有21处PG的患者接受了多点Nd-YAG激光治疗。我们选择单脉冲（脉冲宽度10.5 - 13.5毫秒；能量100 - 125焦/平方厘米）；治疗间隔为3 - 4周。所有病变在一两次治疗后均消失。随访超过12个月，未出现明显瘢痕形成，未影响手指和脚趾功能，未损害指甲生长，也未复发。Nd-YAG激光是治疗位于手指和脚趾的PG的一种有效且安全的治疗选择。
